Alpha Vaculoy Sn63/Pb37 Alloy

ALPHA® Vaculoy 63/37 alloy is manufactured using ultra high purity raw materials and the alloy is  conditioned using Alpha's proprietary viscosity and dross lowering  treatments. This results in a pure, low drossing, high fluidity solder alloy, which is free of cast-in impurities and included oxides.

Key Products Features & Benefits: 

  • 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
