Aluminum Magnesium alloy powder ( Al-Mg alloy powder, Magal ) White powder in silver form thing, Particle size:30~300 mesh, Density:0.4~0.85 g/cm3 , burning send out the dazzling and white light. Chemistry : Mg: 47~53%, Al: 47~53%, live metals ≥ 96.5%, Fe ≤0.4%, Si ≤0.2%, Cl ≤0.02%, H2O ≤0.1%. Use: Al-Mg alloy powder burns easiest, producing the heat with sending out the dazzling and white light, this characteristic is extensive to used for the armament industry, such as manufacturing the flare, signal plays with napalm bomb etc..In firework industry, Al-Mg alloy powder gives out light essentially. Because of its chemistry kind alacrity, in metallurgy industry it is used to take off oxygen, an additive, purifying, refractory material etc.
