Tin-Zinc-Lead Solders Economical solders for
repairing & joining most metals including aluminum and cast iron.
Benefits and Uses
Low application temperatures prevent loss of properties and minimize
distortion. Excellent for use in production processes joining large
surface areas of aluminum. Also used to build up, fill or seal cast iron,
malleable iron, copper, steel and nickel alloys. It can be used in the
repair of Kirksite and galvanized surfaces; also for sealing water
jackets, compressor housings, gear boxes, liners, cast iron radiators, and
for tinning surfaces as a base for Babbitt Metal. Will withstand hydraulic
pressure up to 900 psi.
General Procedure
The joint area must be cleaned and ground, filed or chipped, to improve
strength where vibration is expected. Heat the area of application (NOT
the rod directly). Tin the area thoroughly by rubbing the rod on the
surface, allowing conducted heat to melt the alloy, and then add
additional rod for filling.
When necessary, flux should be applied to ensure bonding. Depending on the
application, Kapp Golden Flux for aluminum soldering or Kapp Comet Flux
may be used for metals except aluminum. Some applications do not require
flux.
The following chart represents our standard tin-zinc-lead alloys. Many
factors, such as materials, temperature, and method of application
determine the end result of any joining operation. Call Kapp Engineering
Assistance to discuss your specific needs. We recommend testing
appropriate alloys in your specific application to ensure suitability.
Samples of Kapp's alloys are always available upon request.
