Carbo Bronze & Brass Valves
Bronze, taking tin as the main alloying element at a content generally from 3% to 14%, is widely used in the production of brass valves and fittings, elastic components, and wear-resistant parts by the bronze valve and brass valves manufacturers. Adding lead and zinc will facilitate the machinability and wear resistance and the casting property of tin bronze, respectively. The alloy is easy to cut, featuring high mechanical properties, antifriction properties, corrosion resistance, brazing & welding performance, low shrinkage coefficient, and disappearance of magnetism. Moreover, tin bronze, as a nonferrous metal alloy, is often used to produce castings with complex shape, clear outline, and low air tightness due to its smallest shrinkage coefficient. Tin bronze valves are quite resistant to the corrosion caused by air, sea water, fresh water and steam, and are widely applied to the manufacture of steam boilers and marine parts.
