Phosphorus in the tin-phosphor bronze tube is a good deoxidizer for copper alloys, which can increase the fluidity of the alloy, improve the process and mechanical properties of the tin-phosphor bronze tube, but increase the inverse segregation. The limit solubility of phosphorus in the tin-phosphor bronze tube is 0.15%. If it is too much, it will form α+δ+Cu3P ternary eutectic with a melting point of 628°C. It is easy to produce hot brittleness during hot rolling, so it can only be cold worked. |

Features and processing: Tin-phosphor bronze tube is a well-known elastic material. During processing, it is necessary to control the grain size before cold working and low temperature annealing after processing. After cold working, the tin-phosphor bronze tube is annealed at a low temperature of 200-260°C for 1-2 hours to produce an annealing hardening effect, which can further improve the strength, plasticity, elastic limit and elastic modulus of the product, and increase the stability of elasticity. |
