Steel 1060

Aging Procedure

Not applicable to this alloy.

Annealing Procedure

Annealing may be done at 650 F followed by air cooling.

Applications

Commonly used in the manufacture of chemical equipment and railroad tank cars.

Cold Workability

The cold working characteristics of AL 1060 are excellent. It can readily be cold worked by all conventional methods.

Forgeability

This alloy may be forged in the temperature range of 950 to 700 F.

Formability

This alloy has excellent forming capability by cold or hot working with commercial techniques.

Hardening Procedure

The alloy hardens only from cold working. Tempers H12, H14, H16, H18 are determined by the amount of cold working imparted into the alloy.

Heat Treatability

This alloy does not harden by heat treatment. It may be annealed after cold working. See "Annealing".

Hot Workability

Hot working, if required, may be done in the range of 900 to 500 F.

Machinability

The machinability of AL 1060 is fair to poor, especially in the soft temper conditions. In the harder (cold worked) tempers such as H16 and H18 the machining characteristics are improved. Either carbide or high-speed steel tooling may be used and use of lubricants is recommended, although some cutting may be done dry.

Other Mechanical Properties

Shear strength of annealed (O temper) is 7 ksi. For H14 temper it is 9 ksi and for H18 temper 11 ksi.

Other Physical Properties

Electrical conductivity 55% of copper.

Principle Design Features

This is a relatively low strength, essentially pure aluminum, alloy. It is noted for excellent welding characteristics and formability along with good corrosion resistance. It cannot be hardened by heat treatment.

Tempering Procedure

Not applicable.

Weldability

AL 1060 may be welded by standard commercial methods. If filler rod is required it should be of AL 1060. A precaution should be noted for the use of resistance welding as by this method some trial and error experimentation may be required to obtain good results.
