Product Information

Phosphor Bronze 1

Alloy No C5102
Characteristics non-corrosion
Applications electronic appliances, relays
Other information P was added to deoxidize the alloy of copper and zinc. Phosphor has high impact strength and strong ductility. So it can be widely used for good quality springs and electronic devices where high conductivity is required.

Phosphor Bronze 2

Alloy No C5191
Characteristics Chemical durability, good strength
Applications Terminal, connector, electronic appliances, communication devices
Other information P was added to deoxidize the alloy of copper and zinc. Phosphor has high impact strength and strong ductility. So it can be widely used for good quality springs and electronic devices where high conductivity is required.

Phosphor Bronze 3 Phosphor bronze for spring

Alloy No C5210
Characteristics Excellent chemical durability and strength, springiness, abrasion resistance
Applications Terminals, connectors, communication devices, springs
Other information P was added to deoxidize the alloy of copper and zinc. Phosphor has high impact strength and strong ductility. So it can be widely used for good quality springs and electronic devices where high conductivity is required.
