Copper 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.

Badger Alloys, Inc. Reported10 lb to 4,000 lb
Bronze sand castings from 10 to 4,000 lb. Useful where a marine bronze casting and a steel casting can come from one pattern shop. Badger publishes its moulding method, which most foundries do not: airset NO-BAKE, giving closer dimensional tolerance and a cleaner surface than green sand at higher cost per mould. Casting weight range 10 to 4,000 lb. No AS9100, NADCAP or military specification qualification is claimed. Defense is one of several markets served.

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.

Badger Alloys, Inc. Reported10 lb to 4,000 lb
Airset no-bake sand casting of bronzes, alongside the steel and stainless range. Badger publishes its moulding method, which most foundries do not: airset NO-BAKE, giving closer dimensional tolerance and a cleaner surface than green sand at higher cost per mould. Casting weight range 10 to 4,000 lb. No AS9100, NADCAP or military specification qualification is claimed. Defense is one of several markets served.

Centrifugal Casting 2
Pouring metal into a rotating mold so centrifugal force drives it against the wall, producing dense cylindrical castings with impurities concentrated at the bore where they are machined away. The standard route for bushings, sleeves and large rings.
