Aluminum Castings
Who pours castings in this alloy, and can they hold my geometry and pour weight?
What it is
Parts produced by pouring molten metal into a mold. For reactive metals this requires vacuum or inert atmosphere melting and specialized mold systems, which is why the qualified supplier list is short.
- Typical dimensions
- Grams to several hundred pounds; envelope limited by furnace and mold capacity.
- Also known as
- cast parts, investment castings, precision castings, cast components
Suppliers
Grouped by what they actually are. A mill and a distributor answer different needs.

Production methods
The same form, purchased as tolling on your own material.
Investment Casting 2
Building a ceramic shell around a wax pattern, melting the wax out and pouring metal into the resulting cavity. For reactive metals the pour is done under vacuum or inert atmosphere against specially formulated shells.

Howmet Aerospace Reported
Confirm which US plant carries aluminum scope.

Signicast VerifiedA356
Investment casting in A356, A355 and 201.0-T6 aluminium for weight-sensitive aircraft and satellite equipment. NADCAP accredited at Hartford, ITAR and AS9100.

Sand Casting 3
Pouring metal into a mold formed in bonded sand. The lowest tooling cost route to a casting and the only practical one for very large parts, at the cost of surface finish and dimensional tolerance.
-
Chicago Magnesium Casting Co. VerifiedAS9100A356
Aerospace sand casting with up to 80 internal cores, under AS9100 and NADCAP.

Lincoln Foundry VerifiedFinished weights 0.01 lb to 100 lb
Sand casting of aluminium at small part weights.
source -
Thompson Aluminum Casting VerifiedAS9100NADCAP Materials Testing Laboratories
Sand casting in a 60,000 sq ft aerospace-approved foundry.

Die Casting 1
Injecting molten metal under high pressure into a reusable steel die. High volume and excellent dimensional repeatability, with tooling cost that only amortizes over large quantities. The dominant route for magnesium components.

Twin City Die Castings Verified
600 ton Colosio machines. A380 is the general purpose alloy; A360 gives higher corrosion resistance and better strength at temperature.
