1. Properties &
Application:
(1). Boron content: 2.5～3.5%. Used for adding boron element
to Al alloy or grain refining of pure aluminum or aluminum alloy in
the course of smelting.
(2). A lot of dispersed AlB2 corpuscles with high
melting point are produced in the process as foreign crystalline
cores when these corpuscles coagulate, notably refining the
crystalline configuration of the cast ingots, improving the
mechanic, electronic and working properties of the aluminum
cast.
2. Operation Instructions:
(1). Temperature: **0~**0℃
(2). Dosage: 0.1~0.5% of the total metal weight.
(3). Method: Skimming off the dross and put AlB3 into the
molten Al, stirring molten to homogeneous, keep the molten Al
static for 5~*0 minutes.
3. Package and Storage:
Appearance: white metal nuggets **0g/pc or waffle ingot
7.5kg/pc.
Keep dry and ventilated.
