Aluminum alloy
319 aluminum castings
Weldable, machines well, and reaches full strength without heat treatment.
319 is a self-aging aluminum-silicon-copper alloy: it reaches its maximum strength about two weeks after casting, with no heat treatment. It resists corrosion, is weldable and machines well.
It suits high-stress parts where heat treatment would add cost or lead time.
We cast 319 in green sand, no-bake and permanent mold, and machine and heat treat it in-house.
- Composition
- About 6% silicon and 3.5% copper, with iron at 1.0% maximum; the balance is aluminum.
