The addition of sulfur to c147 copper gives it excellent machinability and superb conductivity. Additionally, c147 exhibits high corrosion resistance. Hot working is rated as excellent, while cold working is rated as fair. Additionally, c147 is ideally suited to brazing, soldering, and butt welding. Spot welding, oxyacetylene welding, gas shielded arc welding, seam welding, and coated metal arc welding are also suitable but provide lower quality welds. This material is typically used for electrical, industrial, and plumbing applications.
