How Many Kinds Of Aluminum Are There?

According to whether heat treatment strengthening, aluminum alloy is divided into non - heat treatment strengthening aluminum and heat treatment strengthening aluminum. Aluminum has no isomer, so it is impossible to improve the strength of pure aluminum, Al-Mn alloy and Al-Mg alloy by heat treatment phase transformation. However, aluminium-copper and aluminium-magnesium-silicon alloys can improve their strength by precipitation of strengthened phase through solution aging, which is called heat-treatable strengthened aluminum. It is called unheat-treatable strengthened aluminum that can not improve its strength by precipitating strengthened phase through solution aging.
