Application Fields
Frequently Asked Questions
What are the primary elements of this copper alloy?
This alloy is primarily composed of Copper (Cu) as the base metal, with 3.5-4.5% Tin (Sn) and 0.03-0.35% Phosphorus (P) as key alloying elements to enhance its strength and performance.
Why is phosphorus added to this tin bronze material?
Phosphorus acts as a powerful deoxidizer during the melting process. It increases the material's wear resistance, hardness, and fatigue limit, while also improving the fluidity of the molten metal.
What makes this alloy suitable for spring and connector applications?
Due to its high elastic modulus (110–120 GPa) and exceptional fatigue resistance, the alloy can undergo repeated stress and bending cycles without losing its original shape or electrical connectivity.
How does this material perform in marine or wet environments?
It offers outstanding corrosion resistance in seawater, industrial atmospheres, and mild chemicals, preventing rapid degradation and ensuring a long service life for marine hardware.
What is the melting point range of this phosphor bronze alloy?
The melting point range is between 900℃ and 1020℃, which provides excellent thermal stability for high-stress electrical and mechanical components.
