Import Brown Fused Alumina For Sandblasting — Buy in wholesale FOB from Supplier in China

Wenxian Gold Carbon High Temperature Materials Co. Ltd supplies brown fused alumina specifically graded for sandblasting and surface preparation applications, with stated Al2O3 content of 95% minimum and TiO2 between 2% and 4%. The material is available in standard FEPA grit sizes from F36 to F120, covering coarse cutting grades through to fine finishing fractions for diverse metal surface treatment requirements. Produced by electric arc furnace fusion of bauxite, iron oxide, and coke, this synthetic abrasive exhibits the brown colouration characteristic of titanium-bearing alumina and is chemically stable against both acidic and alkaline environments.

The F36 to F120 size range corresponds to particle diameters from approximately 500 micrometres down to 125 micrometres, suitable for aggressive rust removal through to fine matte finishing on stainless steel, aluminium, and carbon steel substrates. Residual Fe2O3 content in standard brown fused alumina contributes to toughness and fracture resistance during impact in blasting nozzles. Typical bulk density for this material falls between 1.60 and 1.95 g/cm3 depending on grit size and packing, with true density around 3.90 g/cm3; hardness on the Mohs scale is 9.0, approaching that of diamond and superior to garnet or silica alternatives for recycled blasting operations.

Application sectors span metal fabrication, ship maintenance, automotive refinishing, and general industrial surface preparation where coating adhesion and controlled surface profile are critical. The supplier packages material in 25 kg bags or 1000 kg jumbo bags, accommodating both small workshop consumption and bulk industrial procurement. Buyers should confirm availability of specific FEPA grades not listed (such as extra-coarse F12-F24 or superfine F150-F220), verify whether washed or air-graded products are offered for reduced dust generation, and determine if the supplier provides material safety data sheets and blasting equipment compatibility guidance.

Wenxian Gold Carbon High Temperature Materials Co. Ltd operates from Chenxin Village, Wenxian County, Jiaozuo City, Henan Province, China (postal code 454850), placing it in the same Henan industrial corridor as other major alumina-based refractory and abrasive producers. The company holds harbour trust tier classification on its marketplace profile. Its response metrics show 0.00% response rate with zero recorded average response hours, indicating potential communication delays that buyers should factor into procurement planning and urgency assessments.

The supplier's product focus is explicitly on brown fused alumina for abrasive blasting applications, with stated technical parameters and standard FEPA grading that suggest familiarity with international abrasive specifications. The source description conveys understanding of wet versus dry blasting techniques, metalworking surface preparation requirements, and refractory secondary applications. No information is provided about production scale, furnace configuration, annual capacity, ISO quality certification, environmental compliance documentation, or export experience. Buyers should independently verify company registration, request factory audit access, and confirm whether the supplier maintains in-house particle size testing and chemical analysis capability or relies on third-party laboratories.
