Alloys We Die Cast
Aluminum, Yellow Brass, Red Brass, and other Special Brass Alloys
Rheocast specializes in cold chamber aluminum die casting and brass die casting. Aluminum and brass alloys produce highly repeatable, complex shapes and at very competitive prices. Each alloy category offers its own unique benefits. High-pressure die castings offer many advantages over other manufacturing processes. Die cast components are stronger, lighter in weight and require less machining than fabricated parts. Complex and intricate shapes can be die-cast in a single homogenous piece which eliminates assemblies and welding.
