Specifications for Solder Wire
-
SRI BHAVANI Solder wires, Lead free Solder, Sticks are manufactured in Solid, Single and Five Cores of Flux. The flux is uniformly distributed throughout the longitudinal axis of the Solder. The fluxes used are activated non corrosive and of fast spreading action. - Only high purity virgin metals are used in the manufacture.
- Available in various metal combinations of Tin, Lead, Silver, Zinc etc.
- SRI BHAVANI Solder Wire, Lead free and Sticks are generally confirming to I. S. 1921 and I.S.193.
- Solder Wires are available upto 22 SWG diameters. Solder Stick are of standard size.
- Solder Sticks with Tin, Lead and Zinc combinations for Aluminium Soldering are available.
- Solder Anodes and other alloys are also manufactured as per customer`s specifications.
