Oxygen-Free Copper Wire With EN 10204-3.1 Certificate ASTM GB Standard OF-CU Wire

Products Specification

Oxygen-free red copper wire has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed. Small amounts of oxygen have little effect on electrical conductivity, thermal conductivity and processability.

ASTM B272

Standard Specification for Copper Flat Products with Finished (Rolled or Drawn) Edges (Flat Wire and Strip)
This specification establishes the requirements for flat copper wire and strip products, with rolled or drawn finished edges produced for general applications. Unless otherwise established by agreement between the manufacturer and purchaser, products shall be produced in UNS Copper Nos. C10100, C10200, C10300, C10500, C10700, C10800, C11000, C11040, C12200, and C14200. The material for manufacture shall be a billet, cake, wire bar, or rod suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Products shall be produced in the annealed (O61) and cold worked (H00, H01, H02, H03, H04, H06, and H08) tempers. Products shall be tested and shall adhere to dimensional (thickness, width, length, straightness, and edge contour), mechanical (tensile strength, elongation, Rockwell hardness, bend angle, and hydrogen embrittlement susceptibility), electrical resisitvity, and chemical composition requirements.
