Recommended for joining all non-ferrous metals, except nickel and aluminium.
Requires no flux on copper, eliminating cleaning problems after brazing.
On brass and bronze, to be used with flux.
Do not use on steel.
Brazing of electrical contacts.
Soldering of copper tubes, cold and hot water installations, heating elements.
!! Do not use for brazing tubes with sulphur containing oils. !!
Hardness: 180 HB
Bonding temperature: 690 °C (1270°F)
Electrical resistivity: 0.25 ohm.mm²/m (0.00001 ohms/in/in²)
Brazing gap: up to 0.5 mm (0.02").
Clean joint area thoroughly and heat the complete joint with a slightly carburizing flame.
When the parent metal is pure copper, you can apply the brazing rod directly.
On brass use flux Lastek 31C (powder), 31CH (powder for thicker pieces) or 31CN (paste).
