Key Words: ASTM B124, B133, B187, Cu/cl NF A53301 (France), BS C110, ISO Cu-OF R1337, CEN CW009A, oxygen free high conductivity copper (OFHC), QQ-C-502, CDA 102 OF
Copper content in composition table includes silver (minimum 99.95% Cu+Ag). Test specimens: rod, 25 mm diam.; shape, 13 mm section.
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.
