ALUMINUM 5086
PRINCIPAL DESIGN FEATURES
This is a high strength structural alloy. It is not heat treatable.
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.
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.
FORMING
Forming characteristics are best with the alloy in the O temper — less good in the H36 or H38 tempers.
WELDING
This alloy is readily weldable by conventional methods. Use of electric arc welding in particular prodsuces excellent results.
HEAT TREATMENT
The alloy is non-heat treatable.
FORGING
No specific data as to hot working range. However the alloy is forgeable.
HOT WORKING
No data in regard to hot forming. Cold forming characteristics are excellent and usually would not necessitate hot working.
COLD WORKING
Excellent cold working characteristics in the O temper and somewhat less good in H36 and H38 tempers.
ANNEALING
Anneal at 650 F for long enough to insure thorough heating. Air cool.
AGING
Not applicable to this alloy.
TEMPERING
Not applicable.
HARDENING
Hardens by cold working only.
