Aluminum Bronze - The most generally accepted disc material used in butterfly valves, aluminum bronze is heat treatable and has the strength of steel. Formation of an aluminum oxide layer on uncovered surfaces makes this metal very corrosion resistant. Silicone Bronze - Has the ductility of copper but much more energy. Silicon bronze has equal or larger corrosion resistance to that of copper. Commonly used as a stem material in strain-rated valves, silicon bronze has larger resistance to stress corrosion cracking than common brasses.

Click right here to comply with our GSL Linkedin firm page for the latest updates. Grey Iron - An alloy of iron, carbon and silicon; simply solid; good pressure tightness in the as-forged condition. Grey iron has excellent dampening properties and is well machined.
Bronze - One of the primary alloys developed in the Bronze Age is usually accepted as the business standard for pressure rated bronze valves and fittings. Bronze has a higher power than pure copper, is easily cast, has improved machinability, and could be very simply joined by soldering or brazing. Bronze could be very immune to pitting corrosion, with common resistance to a variety of chemicals.
