Ensinger PEI

(Viewing data as-entered. Click here to return)
Oxygen-free Electronic Copper (OFE), UNS C10100, H80 (16%) Temper, rod
Categories: Metal; Nonferrous Metal; Copper Alloy; Wrought Copper
Material Notes: Test specimen: rod, 50mm diam.

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 C10100 - ASTM B12, B49,B133, B187, F 68; 101A (Australia); C110 (UK); CDA 101 OFE; ISO Cu-OFE; JIS C1011 H3510 (Japan); QQ-C-502
