Phosphor Bronze PB1

PB1 is a cast material containing 10-11.5% tin and small amounts of phosphorus. Phosphor Bronze PB1 has high mechanical strength and has good conductivity and wear resistance . Also, with excellent corrosion and fatigue resistance. Phosphor Bronze PB1 can be soldered and brazed.

• Hard wearing bronze containing a small amount of phosphorus
• High fatigue resistance
• High tin content reduces the risk of corrosion
• Phosphorus increases wear resistance
• Commonly used in manufacture of bearings, sleeves, thrust washers and gears
