Phosphor bronze sheets and plates are made from a small percentage of copper and tin phosphorus, which increases their strength, corrosion resistance and machinability In typical products 90-95% copper, 5-1. 8% tin, 0.01-0 and .35% phosphorus. These alloys exhibit excellent mechanical properties such as high tensile strength (up to 600 MPa), excellent fatigue resistance and low abrasion resistance, especially corrosion resistance in marine and chemical environments, and also high toughness, Because of their high durability and durability, phosphor copper sheets and plates are ideal for precision applications in a variety of industrial applications.
Phosphor bronze sheets and plates are widely used in industry for strength, durability and corrosion resistance. In marine applications, it is used for ship components such as propellers and shafts due to its anti-seawater properties. In the electrical industry they are used in connectors, switches and spring components due to their excellent conductivity and elasticity. They are also used in the manufacture of gears, bearings and bushings for machinery as their low friction reduces corrosion. In addition, they find value in musical instruments and furniture because of their aesthetics.
