First, we must look at the chemical composition of aluminum hardness, hardness with alloy has a direct relationship. Second, the various states have a greater impact. From the highest possible hardness of view, the 7 Series, 2 lines, 4 lines, 5 Series, 3 Series, 1 Series, in descending order. Second, the strength depends on the aluminum, strength is an important factor that must be considered in product design, especially aluminum alloy component as members, should be based on the pressure, select the appropriate alloy. Minimum strength aluminum, and 2 and 7 Series heat-type alloy the highest intensity. Hardness and strength had a positive relationship considerably. Third, look at the processing performance, including forming properties and cutting and so on. Because with the state of formability, the choice of alloy grades, the need to consider the strength of the scope of the various states, usually forming high strength materials is not easy. If you want to be on the aluminum bending, stretching, deep drawing and other forming process, fully annealed state of the material forming the best, on the contrary, the material forming heat treatment of the worst. Cutting aluminum alloy composition and have a great relationship, usually high-strength aluminum alloy cutting of better contrast, low intensity were poor machinability. For the mold, then write the parts and other necessary cutting products, aluminum
