Mechanical Properties

Phosphorus-copper (phosphor bronze), tin-copper (tin bronze), and tin-phosphorus bronze are bronzes in which a degassing agent, phosphorus, is added with a content of 0.03–0.35%, and tin content ranges from 5% to 8%. Other trace elements such as iron and zinc contribute to excellent ductility and fatigue resistance, making them suitable for electrical and mechanical materials. Their reliability is higher than that of conventional copper alloy products. Bronze was originally referring to copper-tin alloys; thereafter, all copper alloys except brass and cupronickel are called bronzes, and the name often includes the name of the primary additive element. Tin bronze has good casting properties, anti-friction characteristics, and mechanical performance, making it suitable for manufacturing bearings, worm gears, and gears. Standards: GB/T 4423-1992 Chemical Composition: Copper Cu: Remainder; Tin Sn: 6.0–7.0; Lead Pb: ≤0.02; Phosphorus P: 0.1–0.25; Aluminum Al: ≤0.002; Iron Fe: ≤0.05; Silicon Si: ≤0.002; Antimony Sb: ≤0.002; Bismuth Bi: ≤0.002 [1] Note: ≤0.1 (impurities); QSN6.5-0.1 Mechanical Properties of Phosphorus-Copper: Tensile Strength σb (MPa): ≥47; Elongation δ5 (%): ≥13 Note: Longitudinal room-temperature tensile mechanical properties of bars; Sample size: diameter or edge-to-edge distance 5–12; Heat treatment specifications: Hot processing temperature 750–770°C; annealing temperature 600–650°C. Phosphorus bronze has high elastic limit and good conductivity, making it suitable for manufacturing precision springs and electrical contact components. Beryllium bronze is also used to produce spark-free tools for coal mines and oil depots.
