Tool steel, hard alloy, and stainless steel
The commonly used materials for aluminum alloy casting molds include tool steel, hard alloys, and stainless steel. Tool steel is commonly used in mold manufacturing due to its high strength and hardness characteristics, such as grades Crl2, 3Cr2Mo, etc. Hard alloys such as tungsten cobalt alloy and tungsten titanium cobalt alloy are suitable for high-temperature and high-pressure environments due to their excellent high-temperature resistance and good cutting performance. Stainless steels such as SUS420J2 and SUS36 occupy a place in mold manufacturing due to their excellent wear resistance and corrosion resistance. ‌
In addition, the material selection for aluminum alloy casting molds also needs to be determined based on specific die-casting process requirements and usage environments. For example, die-casting aluminum alloy molds usually use materials with high heat resistance, high hardness, high toughness, and high thermal conductivity, such as LG mold steel, to reduce the occurrence of mold cracking.
In the process of aluminum alloy casting, commonly used die cast aluminum materials include ADC 2, which have high performance, high precision, and excellent physical properties, and are widely used in fields such as automotive, electronics, aerospace, etc.
