Die-casting is a type of pressure-casting part. It is a die-casting mechanical die-casting machine equipped with a casting mold. The heated liquid metal is poured into the inlet of the die-casting machine. Size parts, such parts are often called die castings. So what materials are usually available for die casting? Bengbu Longhua Die Casting Machine takes you to find out.

The main alloy materials for die casting are tin, lead, zinc, aluminum, magnesium, and copper. Zinc and aluminum alloys are the most widely used, by magnesium and copper alloys. At present, zinc, aluminum and magnesium alloys are mainly used in the electronics industry.

Die-cast zinc alloy

The molten state of the zinc alloy is very good, with a low melting point of only 365 degrees. Various post-processing can be performed, such as plating. Therefore, it has a wide range of uses. It was also used a lot in the mobile phone industry before, but because of the large ratio, the poor corrosion resistance was gradually eliminated by aluminum alloys. Currently the most used is the bathroom industry. Alloys 2, 3, 4, 5, and 7 are commonly used, and currently the most widely used is alloy 3.

Die-cast aluminum alloy

Aluminum alloy has low density but high strength. It is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . The specific weight of aluminum alloy is only about 1/3 of that of iron, so it is very important in various industries at present, especially in the indispensable role in the lightweight process of aircraft, ships, automobiles, and electronic equipment.

Commonly used are Al-Si-Cu series, and ADC12 (A383), ADC10 (A380) are common. There are also Al-Si-based, Al-Si-Mg-based, and Al-Mg-based. What is currently called aluminum-titanium alloy is modified by adding titanium metal to the above materials. Adding titanium metal can significantly improve the mechanical properties of the product.

Die-cast magnesium alloy

Magnesium alloy is an alloy composed of magnesium and other elements. Its characteristics are: low density, high specific strength, large specific modulus of elasticity, good heat dissipation, good shock absorption, greater shock load capacity than aluminum alloy, and good resistance to organic and alkali corrosion. The specific gravity of magnesium is about 2/3 of aluminum and 1/4 of iron. Therefore, it is widely used in mobile phones, communication equipment and other electronic equipment, auto parts, and medical equipment.

At present, the most widely used are magnesium aluminum alloys, by magnesium manganese alloys and magnesium zinc zirconium alloys. Commonly used grades are AZ91D, AM60B, AM50A, AS41B and so on.

With the continuous improvement of the development level of the domestic manufacturing equipment industry, the equipment level of die-casting machines has also improved significantly, the types of parts that can be manufactured have also been continuously expanded, and the precision and complexity of parts produced by die-casting have also been greatly improved Bengbu Longhua Die Casting Machine believes that in the near future, die castings will better serve our production and life!
