Material selection
Technical properties of machined brass
Understanding material characteristics is critical for design optimization. Our engineering team works primarily with C360 and C260 brass, selecting the right grade for performance, forming, finish, and production requirements.
| Property | C360 Free-Cutting Brass | C260 Cartridge Brass |
|---|---|---|
| Composition | Cu 60–63%, Zn 35.5%, Pb 2.5–3.7% | Cu 68.5–71.5%, Zn remainder |
| Density | Approximately 8.5 g/cm³ | Approximately 8.5 g/cm³ |
| Strength profile | Strong balance of strength and high-speed machinability | Ductile grade suited to forming and deep drawing |
| Machinability | 100% rating | 30% rating |
| Electrical conductivity | 26% IACS | 28% IACS |
| Typical uses | Fasteners, fittings, connectors, turned components | Deep-drawn parts, springs, hardware, decorative components |
Material selection can be reviewed against your geometry, tolerance, forming, conductivity, and finishing requirements.
