Aluminum Alloy 1100 (A91100)
Aluminum Alloy 1100 tubing is a commercially pure, non-heat-treatable aluminum alloy known for its excellent corrosion resistance, high thermal and electrical conductivity, and superior workability. It is widely used in chemical processing, food and beverage industries, and heat exchangers due to its purity and formability.
