BS1400 : LB4 is a leaded bronze LB4 containing approximately 9% lead and 5% tin. Excellent machining properties, very good wear resistance and medium to good corrosion resistance.
LB2 continuous cast leaded tin bronze with good plasticity which maximises strength.
PB2 has a higher lead content than PB1 which gives an excellent resistance to wear.
• 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
