1100 aluminum is an aluminum-based alloy in the commercially pure wrought family. With a minimum of 99.0% aluminum, it is the most heavily alloyed of the 1000 series and the mechanically strongest alloy in this series. It can not be strengthened by heat treatment and keeps the benefit of good ductility, formability, weldability and corrosion resistance. In addition, after anodizing, its corrosion resistance can be further improved and a beautiful surface is obtained.

Application

1100 aluminum alloy is commonly used for HVAC, heat shield, deep drawn applications, cosmetic bottle cap, heat exchanger fins, spun hollowware, dials and name plates, decorative parts, giftware, cooking utensils, rivets and reflectors, and sheet metal work.
