Description & applications
Cuprox is basically an alloy of copper and zinc with small addition of silicon, nickel and manganese to assist deposition. This brazing alloy is recommended to assembly: steels, cast irons, moulded steels, coppers, bronze, brass, nickel silver, cupro-aluminium, nickel and alloys.
Heating can be achieved by induction, torch or by furnace.
Most used in lock-smithing and workshops.
A flux is necessary. Can be used as bare rods with our Cupro-Flux or Poly-Flux as flux coated rods (standard colour as FC: burnt sienna).
