Which metals have the best effect on die casting?

Die casting is a metal forming process in which molten metal is injected into a mold under high pressure to form the desired shape. For the metal with the best die casting effect, it mainly depends on the specific application, performance requirements, and cost considerations of the required product. The following are some common die casting metals and their characteristics: Zinc: Zinc is one of the most easily die casting metals and is economical and practical for manufacturing small components. It has excellent die casting performance and can achieve products with complex shapes, thin walls, and high dimensional accuracy. Zinc alloy has good fluidity and low melting point in its molten state, and is commonly used in the manufacturing of telecommunications, household appliances, and other products. Aluminum: Aluminum is a lightweight metal with excellent corrosion resistance and mechanical properties. Aluminum alloy die castings play an important role in fields such as aircraft, ships, automobiles, and electronic instruments. Its high thermal conductivity and conductivity also give aluminum alloys advantages in specific applications. Magnesium: Magnesium alloy is based on magnesium and composed of other elements. It has advantages such as low density, high specific elastic modulus, good heat dissipation, and good shock absorption. Magnesium alloy die casting parts have a greater ability to withstand impact loads than aluminum alloy, and have better corrosion resistance to materials and alkalis. Copper: Copper alloys have high hardness and corrosion resistance, good mechanical properties, wear resistance, and strength similar to steel. However, due to the relatively high price of copper, it may not be as cost effective as other metals in certain applications. Of course, other metals such as tin and lead are also used in die casting processes, but for public health reasons, lead and tin alloys cannot be used in food processing and storage equipment.
