VACULOY® is manufactured using high purity raw materials and the alloy is conditioned using Alpha's VACULOY® viscosity and dross lowering treatment. This results in a pure low dross high fluidity solder alloy, which is free of cast in impurities and included oxides.
VACULOY® treated prior to casting: this removes finely divided suspended oxides that are found in all virgin raw materials, this increases the fluidity and hence soldering defects.
Melting point of 63sn/37pb alloy: 183° C
