The alloy\u00a0offers corrosion resistance comparable to 302, but it can achieve higher strength after precipitation hardening due to aluminum additions.<\/p>

CWI is the leading producer of aerospace and commercial quality 17-7 spring wire in the U.S. and U.K.<\/p>

CWI has decades of metallurgical experience with processing of 17-7 wire for spring applications.\u00a0 This research and process development optimizes the microstructural characteristics of our 17-7PH\u00ae spring wire to be fully compliant with AMS 5678G. CWI has established tight controls on several wire-drawing parameters and laboratory microstructure evaluations to ensure that the product is fully compliant to AMS 5678G.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
