Magnesium · Product form
Magnesium 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.

Distributors and stockists 1
Companies that hold inventory for resale. Faster and available in small quantities, at a markup. Ask what mill the material came from if traceability matters.
-
OMI Specialty Products Reported
Distributor stock. Establish grade and mill certification per heat rather than from the catalog listing.

Production methods
The same form, purchased as tolling on your own material.
Sand Casting 4
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.

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.
