Heat Treatment of Aluminum 1100
- Anneal
- Strain harden
- Temper
- Heat treating will not harden
Applications of Aluminum 1100
- Food and chemical handling equipment
- Heat exchangers
- Sheet metal
- Plumbing
- Lighting
Machinability of Aluminum 1100
- Grind high-speed steel lathe turning tools to:
- 45-52° top rake
- 12-18° side rake
- 8-10° clearance
- 30-35° cutting edge angle
- Same for carbide tools
- Heavy feeds, deep cuts recommended
- Dry cutting appropriate
- Lard oil and lard oil/kerosene oil blends improve heavy cutting
Workability of Aluminum 1100
- Easily cold or hot rolled, stamped, forged, spun and drawn
- Intermediate annealing unnecessary for consecutive drawing and spinning
- Re-annealing recommended when additional cold work follows substantial cold working
