Die-casting: Hydraulic metal is quickly injected into the mold by a die-casting machine to obtain the corresponding castings, which are generally only used for non-ferrous alloys (mainly aluminum, zinc alloy and copper alloy).
Strength depends on the material first, and then on the process. Forging materials have the best internal fiber structure and comprehensive strength. Die casting is just a kind of casting. Because ordinary die castings cannot be heat treated, the strength after heat treatment is lower than that of similar castings. But the strength before heat treatment is higher than that of the castings without heat treatment.
