## Mechanical properties (typical values, not certified minimums)

| Property | Value |
|---|---|
| Tensile strength | ~470 MPa (H02) |
| Yield strength | ~345 MPa (temper dependent) |
| Hardness | ~80 HRB |
| Density | 8.86 g/cm³ |
| Machinability | ★★★☆☆ (3/5) |
| Corrosion resistance | ★★★☆☆ (3/5) |

## When to choose it

When a copper alloy must flex and survive: tin-phosphorus chemistry gives the best fatigue endurance of the common coppers, plus good conductivity and corrosion behavior for electrical springs.

## When to look elsewhere

Costlier and slower-machining than brass — for static turned parts C360 is the economical pick; for maximum conductivity, C110; for heavy bearing loads, consider aluminum bronze instead.

## Typical applications

- Spring contacts and connector blades
- Bushings and sliding wear parts
- Instrument springs and diaphragms
