Metal die casting is used to produce mass components from a number of raw materials like brass alloy, zinc alloy, aluminum, or magnesium alloy. Brass alloys are sourced in distinct configurations by die casters for making components such as coaxial cables, alloy wheels, and so on. Many types of alloys are used in brass die casting and they are listed below as per the constituents of brass and the applications of the end product.
Brass comprises of zinc, copper, and tin. They are predominantly used in applications wherein dezincification of brass is a must. Dezincification will remove zinc contaminants from admiralty brass and will produce a porous component having copper. To make pressing applications, die casters will use the Alpha brass, as they contain less than 35 percent zinc.
In general, brass alloys contains copper and zinc. However, aluminum brass alloy comprises of copper as well as raw aluminum. Foundries use aluminum brass to produce corrosion-free parts. Another type of brass alloy is duplex brass, which have α and β’ phase, and contain 35 to 45 percent zinc.
For a marine application, Aich’s alloy is predominantly preferred by foundries. Aich’s alloy contains copper, tin, zinc, as well as iron. When the client is high profile like jewels the rich low brass alloy is used in brass die casting since they contain 15 percent zinc only.
Besides, there are different alloys of brass as well which you can die cast to make components from a globally equipped foundry. The brass sourced from Arsenical brass is predominantly used by foundries to manufacture boiler fireboxes. For making ammunition cases, cartridge brass containing 30 percent zinc is used by foundries.
The color of brass popularly is brown. However, there is also the white brass containing more than 50 percent zinc. The greater the element of the zinc, the more brittle will be the brass alloy and hence the application of the end product will be in accordance with the brittleness of brass. For instance, white brass is ideal for manufacturing brass ornaments.
Overall, to make brass components, die casting companies will not only aid in product design but also help to choose the right raw material for the end purpose. Note that the properties of the alloy will determine raw material selection in brass die casting.
