Introduction ● C5210 is the Japanese brands, commonly known as phosphor bronze / phosphor bronze, C5210 phosphor bronze with copper alloy Cu-Sn-P as the main alloying elements known as tin-phosphor bronze [Features] * has good yield strength and fatigue strength · have good elastic properties * Excellent processing forming and bending properties · has good ductility, durability, corrosion resistance · resistant to corrosion, extraordinary for dilute sulfuric acid, hydrochloric acid and fatty acids of high corrosion resistance. High strength, elasticity and abrasion resistance, and easy welding and brazing, in the atmosphere, freshwater and seawater corrosion resistance, good machinability [Applications] · CPU socket, the phone keypad Automotive terminals, connectors and electronic wear parts and anti-magnetic component connectors, electrical connectors · Bellows, spring, harmonica friction plate or electric device parts, precision instrument and meter, auto parts and mechanical elements in electrical components: Grades range of thickness of tin and phosphorus content the content of copper content Japan, USA and Germany C5191 C51900 CuSn6 0.1 ~ 0.8 6.0-7.0 0.1-0.25 REM C5210 C52100 CuSn8 0.1 ~ 0.8 7.0-9.0 0.03-0.35 REM physical properties of copper (1) excellent physical and chemical properties of copper conductivity, excellent thermal conductivity, electrical conductivity copper alloys, thermal conductivity is also very good. Copper and copper alloys for air and water corrosion resistance is high. Copper is diamagnetic substances. (2) good processing properties and good plasticity, easy to cold and hot forming; cast copper alloys have good casting properties. (3) has some special mechanical properties such as excellent friction and wear resistance (such as bronze and brass), high elastic limit and fatigue limit (such as bronze, etc.).
