Bronze is an excellent alloy for precision parts casting. Its composition typically includes copper, tin, zinc, phosphorus and in some
While investment casting can be a viable option with significant advantages for modest runs, it becomes increasingly attractive as production quantities get larger. The key reasons are cost related. First, the tooling costs of investment casting, which can be significant, are spread across more parts, making the per-casting cost lower. Second, it reduces or eliminates expensive machining in many cases. The savings add up as runs increase.
