Phosphor bronze has higher corrosion resistance, wear resistance, and does not spark when impacted. For medium-speed, heavy-duty bearings, the maximum working temperature is 250°C. It has the characteristics of self-aligning, insensitive to deflection, uniform bearing force and high bearing capacity, can bear radial load at the same time, self-lubricating and maintenance-free. Tin phosphor bronze is a kind of alloy copper, which has good electrical conductivity, is not easy to generate heat, ensures safety and has strong fatigue resistance. Tin phosphor bronze socket reed hard-wired electrical structure, no rivet connection or no friction contact, can ensure good contact, good elasticity, and smooth insertion and insertion. The alloy has excellent machining performance and chip forming performance, and can quickly shorten the processing time of parts. Harmonica is also commonly used phosphor bronze as the gong material.
Beryllium copper is a supersaturated solid solution copper-based alloy. It is a non-ferrous alloy with a good combination of mechanical properties, physical properties, chemical properties and corrosion resistance. After solid solution and aging treatment, it has a high strength limit comparable to special steel. Limit, yield limit and fatigue limit, and at the same time have high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance, widely used in the manufacture of various mold inserts, replacing steel production High-precision, complex-shaped molds, welding electrode materials, die-casting machines, injection molding machine punches, wear-resistant and corrosion-resistant work, etc. Beryllium copper strips are used in micro-motor brushes, mobile phones, batteries, and products, and are indispensable and important industrial materials for national economic construction.
