Bronze is an alloy of pure copper added to metals other than zinc and nickel. Tin bronze with tin as the main additive element has excellent casting properties, good mechanical properties and excellent friction reduction properties, and is very suitable for manufacturing turbines, gears and bearings.
Lead bronze is used as a bearing material used in engines and grinding machines today. Aluminum bronze has excellent wear resistance, corrosion resistance and high strength, and is widely used in the manufacture of high-load shaft sleeves, gears, marine propellers, etc. Phosphor bronze has good electrical conductivity and high elastic limit, making it very suitable for the manufacture of precision springs and electrical contact elements.
