Bronze is an excellent alloy for precision parts casting. Its composition typically includes copper, tin, zinc, phosphorus and in some
When steel alloys are required for pumps and valves, the investment casting process should be considered for producing the parts. This is especially true for longer runs, where tooling costs can be distributed over more parts. With investment casting, the excellent precision, surface quality, ability to produce complex parts and reduced need for machining all are attractive to manufacturers of pumps and valves using steel alloys.
