C519 Phosphor Bronze 6% Alloy Wire (CuSn6)
Download PDF
A phosphor bronze, alloy C519 has 6% nominal tin producing higher mechanical strengths with a slight decrease in electrical conductivity when compared to C510 phosphor bronze. Often functionally interchangeable with C510 which predominates in North America, alloy C519 is generally used in Europe.
