Magnesium Cover Flux and Magnesium Flux with Refining Function, Non-Toxic Formula and Melt Protection for Magnesium Alloy Smelting

Spread out and cover all over the surface of the magnesium molten, makes the melt isolated from air, preventing absorb H2, preventing magnesium alloys elements in the melt oxidized or burned up.

Fluxes

Refine fluxes are used for purification of aluminum alloys melt. Dross Fluxes are applied to separate inclusions and slag from melt, and extract aluminum trapped in the dross. Cover flux is used for protecting aluminum and aluminum alloy melt and preventing aluminum oxidation.
