Postalloy® 97-SPL

Postalloy® 97-SPL is a low heat input gas-shielded bronze welding wire. It may be used on steels, stainless steels, cast iron, copper, brass and bronze. Benefits include the following:

  • Minimizes warpage and distortion
  • Especially good on galvanized surfaces
  • Bonds well to various grades of cast iron
  • Weld deposits are highly machinable

Postalloy® 97-SPL is ideal for joining thin sheet metal. The low melting temperature reduces burning of the galvanized coating. It is also excellent for joining dissimilar metals i.e., brass or bronze to cast iron, steel to brass, stainless to bronze, etc.
