Powder flux for general brazing work.

A flux used in TIG applications to shield the rear of a weld joint from oxygen contamination, dissipate heat and oxides during welding and prevent re-oxidation. • Formulated to suit stainless steel and high nickel super alloys • To apply, mix flux with methanol & brush over rear of joint • Sif Purging flux is inert, non-flammable and non-explosive • Ideal for pipe and tube welding applications • Supplied in 500g jar.

Powder flux for silver solder operations.

Fluxes remove surface impurities and improve the weld performance. Can form a paste by mixing with water. A range of Sif fluxes are available to suit many applications.

Sif 101 brazing flux power is manufactured from an original Sif formula and is especially effective for Chrome-molly tube, steel, stainless steel, brazing bronze, brass, copper malleable iron and heat-resistant alloys • It aids deep penetration of filler brazing allow into the joints, resulting in high bond-strength • The flux dissolves to remove oxides rapidly • Sif 101 flux is engineered for frame builders and tube-brazing applications.

A pre-mixed paste at optimal liquidity free of boric acid and suitable for brazing of mild steel and copper alloys.

Powder flux for Tool Tipping or brazing stainless with Sifbronze No 1 or No 2.

Powder flux for fusion welding of stainless.

An active Cast Iron Powder Flux with a working temperature range of 800-1500°C. • Sif Cast Iron Powder Flux allows for deeper penetration of the joints, resulting in higher bond strength • This Powder Flux complies to EN 1045 FH20 • Sif Cast Iron Powder Flux is designed to weld Cast Iron with a Cast Iron rod and can be used with SuperSilicon No9 and Super SG rods.

Powder flux for brazing and welding copper alloys.
