Gold plated phosphor copper tape has high mechanical properties, corrosion resistance, and high elasticity

Analysis of gold-plated phosphor copper:

Phosphorus copper (phosphor bronze) (tin bronze) (tin phosphor bronze) is composed of bronze with added degassing agent phosphorus P content of 0.03-0.35%, tin content of 5-8%, and other trace elements such as iron Fe, zinc Zn, etc. It has good ductility and fatigue resistance, and can be used in electrical and mechanical materials. Its reliability is higher than that of general copper alloy products.
Phosphorus copper, an alloy of phosphorus and copper. Replace pure phosphorus for reducing brass and bronze alloys, and use it as a phosphorus additive in the manufacture of phosphor bronze. It is divided into 5%, 10%, and 15% levels and can be directly added to molten metal. Its function is a strong reducing agent, and phosphorus makes bronze harder. Even adding a small amount of phosphorus to copper or bronze can improve its fatigue strength. To manufacture phosphor copper, it is necessary to press the phosphorus block into the melted copper until the reaction stops. When the proportion of phosphorus in copper is within 8.27%, it is soluble and forms Cu3P, with a melting point of 707 ℃. The melting point of phosphorus copper containing 10% phosphorus is 850 ℃, and the melting point of phosphorus copper containing 15% phosphorus is 1022 ℃. When it exceeds 15%, the alloy is unstable. Phosphorus copper is sold in grooved pieces or granules. In Germany, phosphorus zinc is used instead of phosphorus copper to save copper. MetaIlophos is the name for German phosphozinc containing 20-30% phosphorus. Commercial copper reduced with phosphorus, with a phosphorus content of less than 0.50%, is also called phosphor copper. Although the conductivity decreased by about 30%, the hardness and strength increased. Phosphorus tin is a mother alloy of tin and phosphorus, used in melting bronze to produce phosphor bronze. Phosphorus tin usually contains more than 5% phosphorus, but does not contain lead. Its appearance resembles antimony, it is a larger crystal that shines brightly. Sell in sheets. According to federal regulations in the United States, it is required to contain 3.5% phosphorus and impurities below 0.50%.

High quality gold-plated phosphor copper

Main performance:
High strength and high processability phosphor bronze has excellent bending performance, providing a very smooth stamping surface to reduce impedance and minimize mold wear during stamping. It also has excellent fatigue strength and good stress relaxation ability.
Application:
Use P to remove oxygen from pure copper and bronze (Cu Sn), leaving a small amount of P, and add 1% P to Cu alloy to improve mechanical properties such as toughness, elasticity, wear resistance, and corrosion resistance. Mainly used as wear-resistant parts and elastic components. Computer connectors, mobile phone connectors, high-tech industry connectors, electronic and electrical springs, switches, slots, buttons, electrical connectors, lead frames, vibration plates, and terminals for electronic products.
Industry standards:
This alloy is available for forging and casting purposes. The Japanese Industrial Standards (JIS) include phosphor bronze plates and bars C5111P R，5102P、R， 5191P、R，5212P、R； Phosphor bronze plate and strip C5210P, R (P: plate, R： Article); Phosphorus bronze castings PBC2, 2B, 2C, 3B, 3C (marked B: metal mold casting, C: continuous casting, unmarked: sand casting).
