Aluminum 5086

Aging Procedure

Not applicable to this alloy.

Annealing Procedure

Anneal at 650 F for long enough to insure thorough heating. Air cool.

Applications

Commonly used in the manufacture of unfired, welded pressure vessels, marine, auto aircraft cryogenics, drilling rigs, tanks, TV towers, transportation equipment, and in missile components.

Cold Workability

Excellent cold working characteristics in the O temper and somewhat less good in H36 and H38 tempers.

Forgeability

No specific data as to hot working range. However the alloy is forgeable.

Formability

Forming characteristics are best with the alloy in the O temper -- less good in the H36 or H38 tempers.

Hardening Procedure

Hardens by cold working only.

Heat Treatability

The alloy is non-heat treatable.

Hot Workability

No data in regard to hot forming. Cold forming characteristics are excellent and usually would not necessitate hot working.

Machinability

Machinability in the strain hardened tempers (H34, H36, H38) is relatively good. In the annealed (O temper) machining is difficult, but still can be accomplished. Use of lubricants is advised.

Other Mechanical Properties

Shear strength for O temper is 23 ksi, for H34 it is 27 ksi

Other Physical Properties

Electrical conductivity 30% of copper.

Principle Design Features

This is a high strength structural alloy. It is not heat treatable.

Tempering Procedure

Not applicable.

Weldability

This alloy is readily weldable by conventional methods. Use of electric arc welding in particular produces excellent results.
