The main raw materials for die casting include aluminum alloy, zinc alloy, copper alloy, magnesium alloy, etc. These materials show different characteristics and application fields in the die casting process.
Aluminum alloy
Aluminum alloy is one of the most commonly used materials in die casting, especially in the fields of automobiles, motorcycles, aerospace, etc. Aluminum alloy has low density, high specific strength and specific stiffness, good electrical and thermal conductivity, and strong resistance to oxidation and corrosion. In die casting, aluminum alloy shows excellent process performance, including simple forming and cutting, as well as high mechanical properties and corrosion resistance.
Zinc alloy
Zinc alloy has excellent casting performance, mechanical properties and toughness, and is widely used in traditional mechanical parts, hardware, locks, toys and other industries. Zinc alloy has a low melting point of only 385℃ and is easy to form. In addition, zinc alloy has good electrical and thermal conductivity, vibration damping characteristics and electromagnetic shielding performance. Although zinc alloy has poor corrosion resistance, its surface treatment is convenient and can be directly polished, electroplated and sprayed.
Copper alloys and magnesium alloys
Copper alloys and magnesium alloys are also used in specific applications. Copper alloys have good electrical conductivity and corrosion resistance and are suitable for parts that require high electrical conductivity. Magnesium alloys are often used in products that need to reduce weight due to their lightweight properties.
