AMS: QQ-C-530
Alloy Description: Copper Beryllium (0.4% Pb)
UK: Alloy M25
EU: Alliage M25

C17300 (M25)  high-strength Copper Alloy is nearly identical to C17200/CuBe2, but with a small percentage of lead added strictly to increase machinability performance for high speed screw machining.

Alloy M25, which gets its strength from precipitation heat treating, is used typically in round insertion connector and sensor,  RWMA  applications in the aerospace, oil and gas, marine, performance racing, and plastic mold tooling industries, non-sparking safety tools,  flexible metal hose, bushings, electro-chemical springs and bellows.

BENEFITS of C173 Beryllium Copper:

  • High stiffness for insertion applications
  • Good electrical and thermal conductivity
  • Excellent in for anti-galling concerns
  • Excellent machinability
  • Low friction properties
  • Excellent corrosion and erosion resistance
  • Non-magnetic
