Material Properties
| Property | CAC301 Bronze | S45C Steel |
|---|---|---|
| Life vs SUJ2 pin | 1M cycles | 500K cycles |
| Friction coefficient | 0.08-0.12 | 0.15-0.25 |
| Wear pattern | Bushing wears (softer) | Both surfaces wear |
| Corrosion | Resistant | Needs anti-rust |
Bronze vs Steel Leader Bushings — Which Material Lasts Longer?
Key Takeaway: Bronze outlasts steel 2x (1M vs 500K cycles) due to lower friction against SUJ2 pins and predictable wear (bushing wears, pin protected).
