UNS A91100

1100 is a non-heat-treatable aluminum alloy. It soft and ductile with excellent workability as the most weldable aluminum alloy. Cold working increases its strength. 1100 exhibits excellent resistance under severely corrosive conditions. Great for use when electrical conductivity is required. This aluminum is often used for decorative architectural trim, screens, grills, cold-headed and cold-threaded parts.
