Copper Alloys

Choose by function: C110 pure copper for thermal and electrical conduction (busbars, heat sinks, EDM electrodes), C360 free-machining brass for high-volume turned fittings and valve parts, C260 cartridge brass for formed and decorative work, and C510 phosphor bronze where springs, bushings and wear surfaces need fatigue life.

Pure Copper

Copper C110

$$$

The conductivity king: when watts or amps per gram is the whole point of the part.

220–345 MPa (temper) · 40–95 HRF

Machinability

Brass

Brass C260 (Cartridge Brass)

$$$

The forming brass: stronger and lower-lead than C360, with the classic warm brass look.

~370 MPa · ~55 HRB

Machinability

Brass C360 (Free-Machining)

The machinability benchmark itself: fastest cycle times in the shop, naturally low-friction.

385 MPa · 78 HRB

Machinability

Bronze

Phosphor Bronze C510

$$$

The spring bronze: fatigue resistance and low-friction wear for contacts and bushings.

~470 MPa (H02) · ~80 HRB

Machinability
