Steel 1145

Aging Procedure

Not applicable to this alloy.

Annealing Procedure

Anneal at 650 F and air cool.

Cold Workability

This alloy is very easy to cold work in the softer tempers such as annealed, H12, 14, 16 tempers. It may also be cold worked successfully, but with more difficulty, in the harder tempers.

Forgeability

No data available - consult alloy supplier.

Formability

Forming characteristics of AL 1145 are very good. All conventional forming methods may be used successfully with this alloy.

Hardening Procedure

Hardens by cold working only.

Heat Treatability

AL 1145 is a non-heat treatable alloy. It is strengthened (hardened) by cold working.

Hot Workability

No data available - consult alloy supplier.

Machinability

This alloy is more difficult to machine than most of the aluminum alloys. It is somewhat easier to machine in the H16, 18 or 19 tempers than in the softer or annealed temper.

Other Mechanical Properties

Shear strength values are: Annealed (O temper) 8 ksi. H14 temper 10 ksi. H18 temper 12 ksi.

Other Physical Properties

Electrical conductivity 55% of copper.

Tempering Procedure

Not applicable.

Weldability

Weldability is very good by commercial methods, especially TIG or MIG welding.
