1100 Aluminum

This grade is commercially pure aluminum. It is soft and ductile and has excellent
workability. It is ideal for applications involving intricate forming because it workhardens
more slowly than other alloys. It is the most weldable of aluminum alloys,
by any method. It is non-heat treatable.
It has excellent resistance to corrosion, and is widely used in the chemical and
food processing industries. It responds well to decorative finishes, which makes it
suitable for giftware and applications where eye appeal is a factor.
It has the highest thermal conductivity of any aluminum alloy, and its electrical
conductivity is second only to the E C (electrical conductor) grade.
