Aluminium welding powder 

Aluminium welding powder is China's latest developed a new type of paste,and its liquidity and permeability are stronger than other similar flux.

QJ201 uniform particles for subtle, melting point about 420 °C, applicable to 450 °C ~ 620 °C active temperature range flame brazing aluminium and its alloy.

Main ingredients are alkali metal ,alkalineearths ,fluoride and activator.

QJ401 Aluminum brazing solvent melting point about 550°C, suitable for roughly 550 °C  ~ 620 °C activity temperature range flame brazing aluminium and its alloy.

 Its performance in high temperature more superior in aluminum soldering QJ201.
