Master Bond adhesives

Beryllium Copper, UNS C17300, TF00 Temper wire
Categories: Metal; Nonferrous Metal; Copper Alloy

Material Notes: Good to excellent corrosion resistance. Excellent cold workability; good hot formability. Commonly fabricated by blanking, forming and bending, turning, drilling, tapping.

Applications: springs, flexible metal hose, Bourdon tubing, bellows, clips, washers, retaining rings, and other parts subject to severe forming conditions but require high strength, anelasticity, and fatigue and creep resistance; in parts that require high strength or wear resistance along with good electrical conductivity and/or magnetic characteristics such as navigational instruments, non-sparking safety tools, firing pins, bushings, valves, pumps, shafts, and rolling mill parts.

TF00 temper wire; all sizes; aged 3 hours at 330°C.

Key Words: BeCu; CDA 173, ISO CuBe2Pb, CEN CW102C; Alloy M25
