Master Bond adhesives

Oxygen-free Copper (OF), UNS C10200, M20 temper, flat products
Categories: Metal; Nonferrous Metal; Copper Alloy; Wrought Copper

Material Notes: Flat test specimens, 1mm and 6mm thick.

Applications: busbars, bus conductors, waveguides, hollow conductors, lead-in wires and anodes for vacuum tubes, vacuum seals, transistor components, glass-to-metal seals, coaxial cables, klystrons, microwave tubes, and rectifiers.

Processing: Excellent hot and cold workability; good forgeability. Fabricated by bending, coining, coppersmithing, drawing and upsetting, hot forging and pressing, knurling, roll threading, shearing, spinning, swaging, and stamping.

Corrosion Resistance: Good to excellent. Susceptible to galvanic corrosion when coupled with iron, aluminum, magnesium, lead, tin, and zinc. Good resistance to atmospheric, brackish water, sea water, and non-oxidizing acid corrosion, but avoid heating in oxidizing atmospheres or exposing to oxidizing acids, moist halogens, sulfides, ammonia, or solutions with ammonium ions.

UNS C10200 - ASTM B48, B133, B152, B187, B272, B370, B432; C103 (UK); CDA 102 OF; CEN CW009A; ISO Cu-OF R1337; JIS C1020 H3100 (sheet, plate) (Japan); QQ-C-576
