Aluminum alloy forging is mainly used for forging aluminum alloy. Die casting aluminum alloy belongs to casting aluminum alloy, but mainly adopts die casting aluminum alloy.
Aluminum alloy forging includes A1 Si Mg Cu alloy and A1 Cu Ni Fe alloy. Common forged aluminum alloys include LD2.LD5.LDL0, etc. They contain a variety of alloy elements, but the content is small. They have good thermoplasticity, so they have good forging properties and good mechanical properties. This alloy is mainly used for bearing die forgings and some forgings with complex shapes.
Cast aluminum alloys can be divided into four categories: A1 Si system, A1 Cu system, Al Mg system and Al Zn system. For cast aluminum alloy, in addition to necessary mechanical properties and corrosion resistance, it shall also have good casting properties. Among the cast aluminum alloys, A1 Si alloy is also known as Ming, which has good casting and mechanical properties.
