WeldingGradeBauxite
Welding grade bauxite has tight regulation on presence ofsulfur andphosphorus which are detrimental to the weld. When present at high concentrations, they induce porosity and cracking, and at lower concentrations, they adversely affect the impact strength of the weld. And moisture for welding grade bauxite should not exceed 0.5% because the potential for any moisture present withthin the flux to reduce to hydrogent, if exposed to a welding arc, the molten weld pool absorbs the hydrogen and will induce brittleness into the weld.
