C22600 vs Other Copper Alloys
| Alloy Grade | Type | Key Advantage | Limitation | Best Use |
|---|---|---|---|---|
| C22600 | Silicon Bronze | ⭐ Excellent corrosion resistance + good strength + machinability | Conductivity lower than pure copper | Marine / Industrial / Machined Parts |
| C22000 | Commercial Bronze | High electrical conductivity | Lower strength | Electrical components |
| C51000 | Phosphor Bronze | Excellent wear resistance | Harder to machine | Springs / Bearings |
| C36000 | Free-Cutting Brass | ⭐ Best machinability | Poor corrosion resistance | CNC precision parts |
| C93200 | Bearing Bronze | High load capacity | Heavy / less corrosion resistant | Bushings / Bearings |
