Что такое замак? Что это такое и почему он широко используется в производстве

Сплавы вносят значительный вклад в разработку как хрупких электронных деталей, так и тяжелых узлов, используемых в автомобилях. Например, металл zamak незаметно изменил работу многих отраслей промышленности. Этот металл известен тем, что он прочен, легко поддается формовке и универсален. Слово Zamak происходит из немецкого языка и означает цинк, алюминий, магний и медь. В начале XX века производство латунных сплавов было направлено на улучшение хрупкости предыдущих изделий на основе цинка.

Сегодня замак широко используется в производстве автомобилей, электронных устройств и аппаратуры. Он ценится как за прочную структуру, так и за гладкую отделку, требующую совсем немного усилий. Производство алюминия требует меньше энергии, чем производство других материалов, поскольку он легко плавится, а также привлекателен тем, что его можно перерабатывать. Каждый сорт замака соответствует различным требованиям, например, замак 3 мягче замака 5, который прочнее замака 12. Большинство бытовых и промышленных товаров, изготовленных из металла замак, отвечают растущим потребностям производства, поскольку они практичны и качественны.

Здесь мы расскажем о том, из чего делают металл замак, о его видах, таких как замак 3, замак 5 и замак 12, о его функциях, а также о положительных и отрицательных сторонах.

Замак - это разновидность цинкового сплава

Замак изготавливается из цинка, смешанного с небольшим количеством алюминия, магния и меди. Слово Zamak расшифровывается как Zink, Aluminum, Magnesium и Kupfer - немецкие названия металлов. Благодаря высококачественному литью и внешнему виду, металл zamak популярен в производстве автомобильной, электронной, мебельной промышленности и товаров народного потребления.

Процесс, называемый литьем под давлением, позволяет изготавливать из металла Zamak сложные, прочные и экономически эффективные детали. Сгибание замака в стальные формы, напоминающие готовые изделия, происходит под высоким давлением, что позволяет быстро получить множество сложных форм, требующих лишь минимальной механической обработки. Поскольку температура плавления цинка (около 385°C) ниже, он эффективнее поддается формовке в литейном производстве, чем такие металлы, как сталь или алюминий.

Что такое замак и как его делают?

Zamak - это название, образованное от немецких слов, обозначающих основные металлы: Zink (цинк), Aluminium (алюминий), Magnesium (магний) и Kupfer (медь). В 1920-х годах компания New Jersey Zinc Company создала замак, чтобы помочь преодолеть хрупкость, которой подвержены некоторые цинковые сплавы. Он рассматривается как высококачественный тип цинка, который обеспечивает лучшее литье под давлением, чем большинство других материалов.

Обычно в состав металла zamak входят такие элементы, как цинк 96%, алюминий 4%, немного магния и меди. В результате такого сочетания металлические изделия получаются очень прочными, долго служат и могут быть сформированы в точные формы с высокой точностью.

Ключевые моменты о Zamak Metal

Изюминкой металла zamak является то, что он очень легко поддается литью. Производители могут создавать из алюминия формы с тонкими стенками, которые обычно были бы дорогими или сложными для производства из других материалов. Кроме того, замак имеет полированную поверхность, что позволяет использовать его в деталях, которые нуждаются в покраске или покрытии.

Еще одно преимущество заключается в том, что сталь сохраняет свою форму. Поскольку сталь Zamak не так легко меняет форму, она широко используется в производстве автомобилей и электроники.

Материал прочен относительно своего веса, что делает его привлекательным. В отличие от алюминия, замак весит не так уж мало, но он обладает хорошим уровнем прочности, что делает его полезным для предметов, которые должны быть управляемыми.

Применение металла Zamak

Because it has great mechanical characteristics, zamak metal is applied in many products. In this industry, stainless steel is found in door handles, mirrors and several interior parts. A variety of electronic parts use Zamak because it is both precise and can resist heat.

The furniture sector uses zamak because it is so versatile, fitting into hinges, brackets, and other decorations. Many fancy pieces in fashion include zamak since it is shiny and does not get tarnished easily.

Процесс изготовления замакского металла путем литья

1. Подготовка сплава

To produce zamak metal, you need to combine zinc, aluminum, magnesium and copper in the right ratios. To extract metals from these ones, the raw materials are melted at moderate temperatures. The right ratios are necessary to ensure that zamak 3, zamak 5 and zamak 12 provide the desired qualities.

2. Плавление

The blend of materials is put into a furnace and brought up to the zamak melting point of 385°C (725°F). During this step, the alloy flows very well and is therefore excellent for high-pressure die casting.

3. Литье под давлением

The zamak is melted and then put into a die casting machine to be injected into a metal mold. Thanks to this process, items are shaped into very detailed and sturdy forms. Depending on how the casting will be used, manufacturers select from products classified as zamak 3, zamak 5, or zamak 12, since each is meant for a different purpose.

4. Впрыск и отток

As soon as the zamak is injected, cooling the mold causes the metal to harden fast. After removing the part from the mold, it may not need machining because the alloy has a clean finish.

5. Отделка и покрытие

When the model is cast, it might be polished, painted, or electroplated in materials such as nickel or chrome. The processes improve the look and resilience to corrosion of the manufactured product, mostly when used outside.

Different grades of zamak are available for use in different applications. The most popular cast metals in the industry are Zamak 3, Zamak 5, and Zamak 12. They are suited to specific tasks due to their particular traits.

Zamak 3: стандартный сплав

More of all zamak alloys are made with Zamak 3 than with any other type. It helps set the reference for rating other grades. Most (96%) of a galvanized steel rod is zinc, while the remaining 4% is aluminum, with almost no copper or magnesium. Zamak 3 is popular because it combines strength, flexibility and the ability to be cast well.

Zamak 3 is preferred by many manufacturers as it handles complex shapes and provides strength. Due to its ability to meet both mechanical and surface needs, it is often used for die-casting purposes.

Zamak 5: Обеспечивает большую прочность и жесткость

Compared to Zamak 3, Zamak 5 has a slightly higher concentration of copper. Zamak 5, therefore works well for parts that are required to be tough and have excellent performance.

Still, having a greater strength slightly reduces how ductile and suitable the metal is for casting. This is why Zamak 5 is suitably used for mechanical parts in items like industrial tools, gears, and car connectors.

Zamak 5 is popular with many manufacturers, who like having a stronger form of the base alloy.

Zamak 12: прочность и износостойкость

If the application is particularly tough, Zamak 12 is much stronger and more durable. Since it contains more aluminum and copper than Zamak 3 and zamak 5 alloys, zamak 7 has a more durable structure. When casting, zamak 12 may be less flexible, yet it is most suitable for heavy-duty use.

Many industries select Zamak 12 when parts are expected to be worn over a long period. For instance, they are found in pump housings and die-casts used in power tools that must handle continual wear.

Using Zamak 12 requires a bit more effort in production, but its toughness is very valuable for some appliances.

Чем Zamak лучше других сплавов?

Different materials for casting are compared by considering cost, their effectiveness, how easy they are to handle and their durability. All of these characteristics explain why zamak metal is favored.

It is simpler and less energy-consuming to cast zamak at lower temperatures which means the tools last longer. Since the surface is smooth, you need less time and work to finish it, saving on related costs.

Furthermore, each of zamak 3, zamak 5 and zamak 12 are created for particular applications. There is a zamak alloy for every need, including affordability, strength or durability.

Причины, по которым металл Zamak является предпочтительным?

1. Отличная литейная способность

What makes Zamak metal remarkable is that it can fill detailed molds with no problems. Since the metal melts at a relatively low temperature, it can be shaped into intricate objects for casting. As a result, manufacturers can output smaller parts that require minimal cleanup and cost less to make.

2. Гладкая отделка

The finish of Zamak after casting is even and clean. Because of this, applying a coat or polish is usually unnecessary. Therefore, Zamak is often selected for decorative parts, home items, and purposes where what something looks like matters just as much as what it does.

3. Мощь и долговечность

Zamak 5 and Zamak 12 have strong mechanical characteristics. They are suitable for parts that are used regularly because they are strong and moderately hard. They may not be as durable as steel, but they are effective for several uses.

4. Устойчивость к коррозии (после надлежащей обработки)

Even if they are subject to some corrosion, Zamak performs well where the environment can be managed. Upon coating the steel with nickel, chrome, or similar materials, the toughness of the material increases significantly. So, Zamak can be used inside and for simple outdoor uses.

5. Способность перерабатывать и экономить энергию

Using zamak for manufacturing is proven to be eco-friendly. You can fully recycle plastic, and it remains the same after it is melted and reused. Additionally, since aluminum melts at a low temperature, its casting process uses less energy, which benefits both the economy and the environment.

Проблемы, связанные с металлом Zamak

1. Плохо переносит жару

Zamak does not do well when exposed to very high temperatures. It slowly weakens as it is exposed to temperatures above 100–120°C (212–248°F). Thus, learners should know that ceramic is not useful for engine parts or machinery exposed to extreme heat.

2. Больше весит, чем алюминий

Zamak is slightly denser than aluminum. Products in the aerospace or portable electronics industries that require lightness are likely improved using different materials, as Zamak is heavy. Aluminum or composite material is generally the most common choice in such applications.

3. Должны быть защищены от грубых и суровых условий

Zamak exhibits only a little corrosion resistance. If not painted outside in humid conditions, it will form white rust or small pits on the surface. With this problem, Zamak components should be plated or painted to help safeguard the environment.

4. Некоторые сорта хрупкие

Zamak 12, along with others in this series, tends to be stronger but also more prone to breaking because there is more aluminum content. Consequently, the material isn’t suitable for objects that will experience many bends or flexes. Choosing the proper alloy for the design ensures the metal does not fracture or fall apart.

5. Прочность на разрыв меньше, чем у стали

Zamak doesn’t possess the same tensile strength as metals made from stainless steel or titanium. Appropriate materials can be chosen when the load or impact resistance needs to be at its highest.

Экологические соображения

These days, manufacturing companies need to place greater emphasis on sustainability. Recyclability means Zamak metal is an environmentally friendly material for companies to use. After die-casting, any extra materials are collected and then melted down, which helps save costs by reducing waste.

Due to its low melting point, zamak casting saves manufacturers on energy use. As a result, zamak is safe to use and at the same time, it benefits the environment.

Заключение

When it comes to engineered materials, Zamak metal is a popular choice for many reasons. Zamak 3, 5, and 12, the most common types, are all valuable to the manufacturing business and have their own qualities.

From cars to TVs, from clothing to chairs, zamak is valued for being both effective and economical. Because it can be reused and recycled, this material is seen as an important fit for the future of industry.

When you need an effective, flexible alloy, zamak metal is definitely worth considering, since it has been used in die casting for many years.
