Description

Copper Phosphorus is an inorganic compound primarily utilized as a high-performance metallurgical additive. Its core value lies in its ability to act as a powerful deoxidizer and strengthener in copper and copper alloy production, significantly improving mechanical properties and fluidity. This product is essential for manufacturers in the metallurgy, electronics, and welding industries seeking to enhance the quality and performance of their metal components.

Application

• Primary deoxidizer and phosphorus additive in the production of high-conductivity copper and copper alloys (e.g., phosphor bronze, brass).
• Critical raw material for manufacturing brazing and soldering alloys, where it improves wetting and joint strength.
• Used in the metallurgical industry for alloying and refining processes to control oxygen content and microstructure.
• Employed in the production of friction materials and specialty bearings due to its self-lubricating properties.
• Acts as a catalyst precursor in certain organic synthesis and chemical manufacturing processes.
• Applied in the electronics industry for specific conductive pastes and contact materials.
