Copper-plated piano wire for conductive springs "Mac Wire CP"

Spring forming processing, low-temperature heat treatment possible! Piano wire for springs with copper plating using an electroplating method.

"Macguire CP" is a high-strength copper-plated piano wire developed primarily as a spring material requiring conductivity, featuring excellent corrosion resistance, outstanding coiling properties, and spring characteristics. Since copper plating is unnecessary after spring forming, it eliminates concerns such as spring entanglement, spark marks, hydrogen embrittlement, uneven plating around the copper coating, and poor plating in the spring contact areas that may arise during post-plating. 【Features】 ■ Equivalent level to spring phosphor bronze wire ■ No degradation in conductivity even if the copper-plated surface discolors due to oxidation ■ Possesses very excellent coiling properties unique to copper plating and also excels in soldering performance ■ Even if the copper-plated surface discolors due to oxidation, it has high corrosion resistance that can sufficiently withstand 96 hours in a salt spray test against the base steel *For more details, please refer to the PDF document or feel free to contact us.
