Materials Selection Comparison: C94100 vs. C93600
When selecting high leaded tin bronze for bushings, compare C94100 (ASTM B505/B584) with C93600 for optimal performance in low-speed, high-pressure setups (<25 MPa). C94100 stands out with higher lead content for better embeddability of dirt and superior boundary lubrication, making it ideal for self-lubricating C94100 for pumps and heavy load operations.
| Feature | C94100 (CuPb20Sn / High Leaded Tin Bronze) | C93600 (Leaded Tin Bronze) |
|---|---|---|
| Composition | Cu 72-79%, Pb 18-22%, Sn 4.5-6.5%, Zn 1-4% | Cu 80-85%, Pb 11-13%, Sn 4-6% |
| Self-Lubrication | Excellent (high Pb for boundary conditions, 30-50% longer life) | Good (moderate Pb, suitable for lighter loads) |
| Corrosion Resistance | Superior (resists chemicals, seawater, dirty environments) | Moderate (prone to pitting in harsh settings) |
| Wear & Embeddability | High (low friction coefficient, handles impurities without scoring) | Fair (higher risk of galling under contaminants) |
| Strength (Tensile) | 200-220 MPa, HB 60 hardness | 240-290 MPa, HB 65-75 hardness |
| Best For | Steel mill bearings, mining, pumps (heavy, slow-speed) | General machinery (medium loads) |
| Cost Efficiency | Economic for bulk; easy casting/machining | Slightly higher material cost |
