Nocolok Al-Flux

Properties:

white crystal powder, average particle size 3.5-8.0um and all through 500 mesh sieve; composed by KF-AlF3, Molecular rate near 1.2, melting point 557-565. Solubility in 1000g water at 20 is 0.23 0.33g/cm3, density: 2.7 g/cm3, bulk density: 0.35-0.55g/cm3. PH value in water: 6-7. It is clear and transparent while melting and highly active under high temperature; It can get ride of Al2O3 coating on Al surface to make the brazing agent spread evenly and wetly. It also has good joint filling property through capillary. Under normal temperature, after brazing, the glass-like residues is insoluble in water, nonhygroscopic, non-corrosion and demonstrates completely inactive. The usage quantity of this brazing agent is quite less, especially when braze under the protection of Nitrogen. It doesnt need to be washed after brazing and its usage is convenient, which shows its great advantage.

Application: widely used to braze Al-Al, Al-Al alloy and Al- stainless steel in process auto air-condition, Al evaporator, Al radiator, boiler and Al alloy components etc. 

Packing: in 25kg plastic woven bags or 40kg fibre drums with film lining.
