Sn96.5Ag3Cu0.5 and Sn95.5Ag4Cu0.5 and their replenishment alloys Sn97Ag3Cu0, Sn96.5Ag3.5Cu0 and Sn96Ag4Cu0 are lead-free alloys suitable for use as a replacement for Sn63 alloy. The replenishment alloys are sometimes 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. Melting point of SACX 305 alloy is 217-221° C.

Features:

• Yield – Best in class yield, out performs all Sn/Cu based materials
• Wetting speed – fast wetting, in back to back tests 0.65s compared to 1.00s, for Sn/Cu based materials
• Dross generation – Low dross generation delivered by Vaculoy alloy conditioning

• Excellent solderability due to fast wetting speed
• Very good drainage, has lower levels of bridging compared to Sn/Cu alloys
• Delivers excellent performance across a wide range of Flux technologies
