Aluminum alloys in type 6xxx are (6061, 6063) composed of silicon And magnesium.
In the amount of magnesium silicide (Mg2Si), which makes it possible to heat the process. It has the same hardness as Type 2xxx and 7xxx. This type of 6xxx can be made well, easy to weld, easy to process and resistant to corrosion. With moderate strength. Aluminum grades in the type can be made. heat-treatable This can be molded in the T4 temper (solved the problem of heat. It can not accelerate the heat treatment) and increase the hardness after forming the T6 properties by accelerating the heat treatment.
