1100 nhôm lá cuộn lớn

Aging:

This material will not age, but can oxidize when left in an extremely damp environment and/or when Exposed to extreme temperatures in both hot and cold environments.

Annealing:

Annealing, which may be necessary after cold working. The material is heated to 650°F and then air cooled.

Applications:

Commonly used as tapes, fin stock, heat exchanger fins, tags, and name plates, commercial filters, decorative applications, giftware, and reflectors, and in sheet metal work.

ASTM Standards:

B479

Cold Working:

This is a excellent alloy for cold working because of the good malleability in the annealed temper. It can easily be bent, drawn, or spun into a variety of applications.

Finish:

Standard Finishes

Forging - Hot Working:

Hot working can be conducted when needed. The alloy can be hot forged.

Forming - Welding:

Forming either hot or cold is readily accomplished with this alloy. In the annealed condition this alloy can be cold worked extensively without an intermediate anneal. Easily welded by all conventional methods.

Hardening:

Hardens during cold working only.

Heat Treatment:

This alloy does not respond to heat treatment other than to anneal the material into a soft or O Temper material.

Other Physical Properties:

Electrical conductivity is 53% of copper.

Principal Design Features:

This alloy is 99.0% min pure aluminum with excellent ability to be formed and worked.
