FAQ
What is the hardness of aluminium ADC12?
ADC12 is an aluminum alloy that is commonly used in die casting applications. The hardness of ADC12 can vary depending on the specific heat treatment and manufacturing process used. Typically, the hardness ranges from 80 to 95 Brinell hardness (HB) for the as-cast condition, and up to 140 HB when heat-treated to T6 temper. However, it’s important to note that the exact hardness may also be affected by other factors such as the thickness of the casting, cooling rate, and section size.
Is ADC12 heat treatable?
Yes, ADC12 (Aluminum alloy) is heat treatable. Heat treatment is a common method used to increase the strength and hardness of aluminum alloys like ADC12. The T6 temper, which involves solution heat treatment and artificial aging, is the most commonly used heat treatment for ADC12. This process improves mechanical properties such as tensile strength and hardness. However, it’s important to note that heat treatment may also affect other material properties such as ductility, toughness and dimensional stability, so careful consideration should be given before deciding on the appropriate heat treatment for ADC12.
