Standard of nickel plated phosphorus copper wire
Nickel-plated phosphorous copper wire can withstand high temperatures and prevents deterioration due to surface oxidation of the copper wire even when used at high temperatures in the presence of oxygen. Excellent oxidation and corrosion resistance. The addition of phosphorus also improves resistance to wear.| Size (mm) | Tolerance (+-) | Tin layer (um) |
