Centrifugally Formed Foundry Castings
A turnkey Castings Foundry: Superior product integrity at a lower cost
JCT’s foundry castings are produced using advanced centrifugal technology that undergoes the most rigorous, final quality inspection. Our sophisticated castings foundry can convert cast and forge designs to centrifugal castings, working with the full family of copper based, stainless steel, aluminum, and custom nickel and copper alloys.
No one style of manufacturing method is right for every application, and centrifugal castings are no different. Here is where JCT excels:
- When centerline shrink is an issue
- Part can rotate on an axis that is round
- Static casting material properties are inadequate
- Limited ID features
- Net shape when finishing is expensive, and tooling is justifiable
- When quality is causing production flow stoppages due to product defects
ALLOYS
JCT is the only facility in the US to offer vertical centrifugal castings in Bronze/Brass, Steels, and Aluminum! JCT can custom blend any alloy to meet specific customer needs and to tighter tolerances than industry standards, increasing the performance of the metal component
- All Copper based cast alloys (except silicon bronze and beryllium copper) from pure and chrome modified pure copper, through all bronze and brass grades.
- All Aluminum-based cast and wrought equivalent alloys such as 6061, 7075 and 5052, to cast grades such as A356 and A771. Custom alloys available in small lot sizes.
- Cast stainless steels contained in ASTM A743, A297, and A351, and in the 18-8 and martensitic families as well as specialized heat and wear resistant alloys.
- Many custom Nickel and Copper-Nickel alloys
