Import Blasting Media 14# 16# White Korund Grain — Buy in wholesale FOB from Supplier in China

White fused alumina grain from Zhengzhou Haixu Abrasives is produced by melting alumina above 2000 degrees C in an electric arc furnace, yielding alpha-Al2O3 crystal structure with confirmed Al2O3 content of 99.2 percent, Fe2O3 at 0.04 percent, Na2O at 0.26 percent, and SiO2 at 0.02 percent. The 14# and 16# sieve fractions are standard grades for precision blasting operations where controlled surface roughness and minimal substrate contamination are required. The material is processed in a tilting electric arc furnace to achieve higher bulk density and lower porosity than standard fused alumina, improving volume stability under thermal shock during repeated blasting cycles.

The white corundum grain exhibits Mohs hardness of 9.0 and bulk density of 3.60 g per cm3, placing it among the hardest commercially available blasting media suitable for ferrous and non-ferrous metal surface preparation. Its angular fracture pattern and high friability allow the grains to maintain cutting efficiency while breaking down to finer particles that can be extracted by dust collection systems. The material is chemically inert, making it compatible with subsequent coating processes without risk of surface contamination from iron oxide or silica residues. Typical applications include turbine blade finishing, medical implant surface texturing, and aerospace component preparation where aluminium oxide contamination must be avoided.

This blasting media is purchased by surface treatment contractors, foundries, automotive remanufacturing plants, and precision engineering workshops. It is commonly packaged in 25 kg bags for international shipment, though buyers should confirm current packaging options, minimum order quantities, and Incoterms directly with Zhengzhou Haixu Abrasives. The supplier's location in Henan Province, a major refractories and abrasives manufacturing region in China, positions it within established raw material supply chains for high-purity alumina feedstock.

Zhengzhou Haixu Abrasives Co., Ltd. is headquartered in Erqi District, Zhengzhou City, Henan Province, China, with its registered address at Room 1903, Yaxing Times Plaza. The supplier holds an imported tier classification on the platform and a harbor trust tier. The response rate is recorded at 0.00 percent with zero average response hours, indicating that direct communication attempts through the platform have not yielded measurable engagement. Buyers should expect to establish contact through alternative channels and verify responsiveness before relying on platform messaging alone.

The company specialises in white fused alumina products manufactured via electric arc furnace processes, with this listing focused on 14# and 16# white corundum grain for blasting applications. No information is provided about production capacity, workforce size, revenue figures, specific client relationships, or third-party certifications. The listing does not state ISO certification, environmental management systems, or laboratory accreditation. Buyers should request documentation of quality control procedures, batch testing protocols, and material safety data sheets during initial discussions.
