(2) C5102: 4.5% to 5.5% Sn, 0.03% to 0.35% P,> 99.5% (Cu + Sn + P). (3) PBC2: 87.0% to 91.0% Cu, 9.0% to 12.0% S, 0.05% to 0.20% P (2B: 0.15% to 0.50% P;
Performance and use of editing
Phosphor bronze has a higher corrosion resistance, wear resistance, the impact does not occur when the spark. For medium-speed, heavy-duty bearings, the maximum working temperature of 250 ℃. With self-aligning, insensitive to deflection, the bearing capacity of uniform bearing capacity can be subject to radial load, self-lubricating maintenance-free features. Tin phosphor bronze is an alloy copper, with good electrical conductivity, easy to heat, to ensure safety while having a strong anti-fatigue. Phosphor bronze jack reed hardwired electrical structure, no rivet connection or frictionless contacts, to ensure good contact, good elasticity, dial a smooth. The alloy has excellent machinability and performance of the chip can be quickly reduced parts processing time. Harmonica also commonly used phosphor bronze as a spring material.
