Product Detail Information


Welding grade bauxite

Welding flux, as a granular material, it can melt to be welding slag and gas for protecting the weld pool.

High-strength bauxite is one of the main raw material in the welding industry, owns important position in thermit products 101, 301 and 501, Sinocean welding bauxite acquires many praise from thermit and welding rod factories for years.

Sinocean welding bauxite is produced by a series of steps, special mine, strict sorting, high-temperature calcination, cold annealing to ensure the good refractoriness and toughness, getting rid of poor and impurity, Sinocean welding bauxite with high content on Al2O3, low content on S and P is got finally.



Raw material for welding electrode production; 

Used in submerged arc welding to shield the molten weld pool from the atmosphere during the weld’s application.


Advantage of Sinocean bauxite 

Best quality and competitive price.

Self-owned mines, automatic production line, strict quality control and fast delivery.
