Phosphor bronze has higher corrosion resistance, is resistant to wear and tear, and does not spark on impact. For medium speed, heavy load bearings, working at a maximum temperature of 250 ℃. With self-aligning, insensitive to deflection, shaft bearing force uniform high bearing capacity, can be subject to radial load at the same time, self-lubrication without maintenance and other characteristics. Tin-phosphor bronze is an alloy copper, with good electrical conductivity, not easy to heat, to ensure the safety of the same time with a strong fatigue resistance.
Phosphor bronze is an alloy of copper with tin and phosphorus, which has a hard texture and can be made into bearings. P is used to remove oxygen from pure copper and bronze (Cu-Sn) and a small amount of P remains, as well as Cu alloy with 1% P added to improve mechanical properties (toughness, elasticity, wear resistance, corrosion resistance). It is mainly used as wear-resistant parts and elastic components.
Phosphorous Bronze Bushing Properties And Characteristics
Strength and resilience – phosphor bronze is a fatigue-resistant alloy. It holds up exceptionally well to wear. The inclusion of tin is what gives photo bronze its added strength, and phosphorus gives it a greater wear resistance.
Corrosion resistance – this alloy is commonly used in applications where it will have exposure to corrosive chemicals and/or physical elements.
Electrical conductivity – the use of phos bronze in electrical components is perhaps its most well-known application.
Excellent elasticity – the fine grain size of this alloy enables the material to have a greater degree of spring back.
C54400 Phosphorous Bronze Bushing
ASTM Standard B103 (B103M-2009)
JIS standard C5440
C54400 phosphor bronze has excellent machinability and good cold workability because it contains Pb. C54400 phosphor bronze is mainly used as bearings, bushings, gears, shafts, thrust rings and other parts.
Phosphorous Bronze Bushing In Automotive Manufacturing
Phosphor bronze is the most widely used bushing material in automobile manufacturing. It is widely used in connecting rod bushings of air compressors, refrigerators and internal combustion engines, cross pin bushings, piston pin bushings, camshaft bushings, guide Wheel bracket bushings, gearbox bushings, etc. It is characterized by high hardness, good wear resistance, low friction coefficient, good impact toughness, high allowable specific pressure and limit linear speed, and good manufacturability. Phosphorus in phosphor bronze can prevent extremely hard and brittle SnO2 from being produced in the alloy, and has a protective effect on the journal. Therefore, the use of phosphor bronze as the bushing material is beneficial to prolong the mechanical life.
