Tin, lead, zinc, aluminum, magnesium, copper, and other alloy materials are the most common materials used in die casting. The most popular alloys are made of zinc and aluminum, followed by copper and magnesium alloys. At this time, the electronics sector mostly uses alloys made of zinc, aluminum, and magnesium.
Zinc alloy die-casting
The melting point of zinc alloy is as low as 365 degrees, and it possesses excellent fluidity in the molten condition. There are many post-processing procedures that may be used, including electroplating. As a result, it has several applications. It was once heavily utilized in the mobile phone sector as well, but because of its high ratio and subpar corrosion resistance, aluminum alloys increasingly replaced it. The sanitary industry is now the one that uses it the most. Alloys 2, 3, 4, 5, and 7 are often employed, with alloy 3 being the most popular at the moment.
Aluminum alloy die-casting
Aluminum alloy has a low density but a strength that is comparable to or greater than premium steel. It can be processed into many different profiles and has high plasticity. It has good corrosion resistance, thermal conductivity, and electrical conductivity. It is second only to steel in terms of the amount of use in industry. Since aluminum alloy has a specific weight that is only around one-third that of iron, it is used extensively throughout society, particularly for lightening vehicles, electronic equipment, airplanes, and ships.
The Al-Si-Cu series is the most widely used, and examples include ADC12 (A383), ADC10 (A380), and others. Al-Si series, Al-Si-Mg series, and Al-Mg series are additional. In addition, by adding titanium metal to the aforementioned elements, what is now known as an aluminum-titanium alloy is enhanced. The mechanical qualities of the product can be greatly enhanced by the use of titanium metal.
Magnesium alloy die casting
An alloy made of magnesium and other elements is known as magnesium alloy. It has a lower density than aluminum alloy, a higher specific strength, a larger specific elastic modulus, good heat dissipation, strong shock absorption, a higher impact load capacity, and good resistance to organic matter and alkali corrosion. Magnesium has a specific gravity that is around two thirds that of aluminum and one fourth that of iron. As a result, it is frequently utilized in medical equipment, vehicle components, communication devices, and other electrical devices.
The most popular magnesium alloys right now are magnesium-aluminum alloys, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. Grades like AZ91D, AM60B, AM50A, AS41B, etc. are often utilized.
