What materials are commonly used in zinc alloy die casting?

　　Traditional zinc alloy die-casting includes alloys 2, 3, 4, and 5/7, with the most widely used being zinc alloy 3. In the 1970s, high aluminum based alloys ZA-8, ZA-12, and ZA-27 were developed.

　　Zamak3: Good fluidity and mechanical properties. Applied to castings with low mechanical strength requirements, such as toys, lighting fixtures, decorations, and some electrical appliances. Zamak5: Good fluidity and mechanical properties, suitable for castings with certain requirements for mechanical strength, such as automotive parts, electromechanical parts, mechanical parts, and electrical components.

　　Zamak2: Used for mechanical parts with special requirements for mechanical performance, high hardness requirements, good wear resistance, and general dimensional accuracy requirements.

　　ZA8: It has good impact strength and dimensional stability, but poor fluidity. Applied to die-casting workpieces with small dimensions, high precision and mechanical strength requirements, such as electrical components.

　　Superloya: With the best fluidity, it is suitable for die-casting thin-walled, large-sized, high-precision, and complex shaped workpieces, such as electrical components and their boxes.
