MacDermid Alpha Electronics Solutions products

Sn96.5Ag3Cu0.5 and Sn95.5Ag4Cu0.5 are lead-free alloys suitable for use as a replacement for Sn63 alloy. The Sn97Ag3 and Sn96Ag4 variants are used to stabilize / reduce the copper content in the wave solder bath, this requirement will depend on process conditions. As with all Alpha Metals bar solder, Alpha’s proprietary Vaculoy® alloying process is used to remove certain impurities, particularly oxides.
