IN 1982 CC483K | CuSn14
B14 | Bronze Copper Alloy Tin
Available formats: Bars, Tubes, Caps, Plates and Plates.
The B14 alloy is a very hard, tough bronze with good sliding properties and excellent corrosion resistance. Withstands great efforts, impacts, wear, abrasion, fatigue and high temperature; resistant to high hydraulic pressures, good anti-friction quality. Relatively with good resistance to cavitation and corrosion by seawater.
The UNS C90900 copper alloy can be welded using brazing, soft welding, oxyacetylene welding, gas protection arc welding, coated metal arc welding and carbon arc welding techniques The UNS C90900 copper alloy can be relieved the voltage at a temperature of approximately 260 ° C (500 ° F). The time needed to relieve stress is 1 hour / inch thick. It does not respond to heat treatment.
Applications
Hydraulic elements and parts of valves for high pressure, axial piston cylinders, refrigeration machinery, straight or helical crowns for industrial gearboxes and elevators, gears, pinions, worm screws, nuts and toothed parts subject to very great efforts and speeds; for its maximum
performance is advised to work submerged in oil.
