High-Tin Bronze Alloy C91000
C91000 is a high-tin bronze alloy composed primarily of copper (around 85–88%), with a notable tin content (8–10%), and small percentages of phosphorus and other elements to enhance strength and wear resistance. This alloy is designed for demanding mechanical applications where durability, strength, and resistance to corrosion and fatigue are critical.
Key Characteristics:
- High Strength and Toughness
- Excellent Wear Resistance
- Superior Corrosion Resistance (including seawater)
- Good Fatigue Resistance
- Outstanding Performance in High-Load Applications
- Excellent Bearing Properties
Also referred to as CDA 910, C910 Bearing Bronze, or simply High-Tin Bronze, this alloy is recognized for its ability to withstand heavy loads, high impact, and corrosive environments. C91000 offers superior longevity in applications where metal-to-metal contact is common, making it ideal for heavy-duty and high-performance components.
C91000 is particularly well-suited for:
- Bearings and bushings (especially in high-load or slow-speed conditions)
- Gear worm wheels
- Marine hardware
- Pump components
- Valve stems and seats
- Industrial machinery parts
- Hydraulic equipment
Due to its high tin content and tightly packed microstructure, C91000 resists galling and maintains integrity under extreme service conditions. Its reliable performance in marine and heavy industrial environments makes it a staple choice for industries such as mining, marine, power generation, and heavy manufacturing.
