Bonded Tools Cup Grinding Brown Fused Alumina from Zhengzhou Haixu Abrasives Co., Ltd. are manufactured using brown aluminum oxide grains with a minimum Al2O3 content of 92%, produced by smelting bauxite and anthracite coal in electric-arc furnaces above 2000°C. The material exhibits a Mohs hardness of 9.0, a melting point of 2250°C, and a bulk density between 1.53 and 1.99 g/cm³, making it suitable for aggressive grinding tasks on ferrous metals and cast iron. These wheels are bonded with ceramic or resin matrices to maintain structural integrity under high thermal loads during continuous operation.
Brown fused alumina in this form is typically used in grit sizes ranging from 8# to 220# and micro-powders up to F800 (FEPA), with grain sizes available in 0-1mm, 1-3mm, and 5-8mm fractions. The chemical composition includes SiO2 below 2%, Fe2O3 under 2%, and TiO2 below 4%, ensuring low contamination in finished surfaces. Standard industry practice uses this material for both bonded and coated abrasives, where high toughness and thermal stability are required. It is also used in refractory linings and thermal spray coatings due to its resistance to chemical attack and thermal shock.
This product is purchased by metal fabrication shops, foundries, and precision grinding facilities for stock removal, deburring, and surface preparation of carbon steel, alloy steel, and bronze components. Buyers commonly specify grit sizes between 36# and 120# for heavy-duty cup wheel applications. Packaging is export-grade in 25kg kraft paper bags or 500kg woven polypropylene sacks. Trade terms are typically FOB Zhengzhou or CIF port, with lead times of 15 to 25 days after deposit. Minimum order quantities are negotiable based on container volume.

Before ordering, verify the exact Al2O3 content, grain size distribution, and bulk density with a material certificate. Confirm that the supplier provides batch-specific test reports for chemical composition and physical properties. Do not rely on generic marketing claims; request a sample for grinding trials under your actual operating conditions. Check for consistency in grain shape and absence of excessive fines, which indicate poor smelting or processing.
Confirm the Incoterms offered - typically FOB Zhengzhou or CIF port - and ensure the supplier handles export documentation correctly. Lead times are generally 15 to 25 days after deposit, but may extend during Chinese holidays. Packaging must be moisture-resistant, with inner plastic lining in sacks. Payment terms are commonly 30% advance, 70% against BL copy. Request a packing list with gross/net weights per container for customs clearance.
Inspect the material upon arrival for moisture, clumping, or foreign matter. Perform a simple sieve analysis to verify grit size distribution matches the order. Use a magnet to check for iron contamination, which can indicate impure smelting. Request a certificate of conformity and ensure the supplier provides traceability by batch number. Retain samples for future quality audits, especially if the product will be used in safety-critical grinding operations.
