Leaded Tin Bronze Alloy C91100
C91100 is a high-performance leaded tin bronze alloy known for its exceptional strength, corrosion resistance, and wear properties. This alloy typically consists of 88–90 percent copper, 5–7 percent tin, 2–4 percent lead, and small additions of zinc and other elements. Its superior balance of strength and ductility makes it a standout material for heavy-duty industrial applications.
Key Characteristics:
- Excellent Load-Bearing Capacity
- Superior Wear ResistanceSuperior Wear Resistance
- Good Machinability
- High Thermal Conductivity
- Excellent Corrosion Resistance, Including in Saltwater Environments
- Good Conformability and Embeddability
Also referred to as CDA 911, C911 High-Leaded Tin Bronze, or C91100 Bronze, this alloy is widely used in demanding bearing and bushing applications. It is particularly effective where continuous lubrication may be difficult, and where the alloy must perform under heavy loads at moderate speeds.
C91100 is commonly used for:
- Industrial Bearings and Bushings
- Hydraulic Equipment Components
- Marine Hardware and Fittings
- Worm Gears and Pump Impellers
- Heavy-Load Slides and Wear Plates
- Press Bearings and Guide Blocks
Thanks to its excellent wear characteristics and resistance to brine and seawater, C91100 is a preferred choice in marine, automotive, and industrial sectors. Its robust mechanical profile ensures reliable performance under stress and over time.
