Minghe - Copper Casting

High hardness, strong corrosion resistance, the best mechanical properties of commonly used die-casting metals, wear resistance, and strength close to steel. Conventional hot work die steels are available, such as H13, SKD61, DH-31S, 8407, W302. Due to the high temperature of the alloy liquid during the production of copper alloy die-casting, the thermal shock to the mold is greater, and the mold is more prone to thermal fatigue, cracks and cracks. Some heat shock-resistant materials are better now. For example, 8418 in Sweden and so on.
