Chemical composition varies with grit size: coarser grits (F/P 4#~80#) carry higher Al₂O₃ content, while finer grits (F/P 180#~220# and above) show slightly lower Al₂O₃ and correspondingly relaxed limits on Fe₂O₃ and TiO₂.
F Grit covers the standard range F4~F320. P Grit spans P24~P2500, with P8~P220 as the common abrasive range and microgrits extending to P2500. Products are available to FEPA, GB, and JIS standards.
F Grit: Bonded Abrasives & Blasting
Bonded Abrasive Manufacturing: Vitrified-bond and resin-bond grinding wheels, mounted points, etc., suitable for grinding high-tensile-strength metals such as carbon steel, general alloy steel, malleable cast iron, and hard bronze
Blasting & Surface Treatment: Blast cleaning and surface profiling of aluminum extrusions, copper profiles, glass, precision molds, and washed denim
Lapping & Polishing: Precision lapping of optical glass, monocrystalline silicon, lenses, watch glass, crystal glass, and jade
Functional Fillers: Wear-resistant floors, highway surfaces, aircraft runways, parking lots, sports surfaces; automotive brake components and special tires
P Grit: Coated Abrasives & Precision Lapping
Coated Abrasive Manufacturing: Raw material for sandpaper, abrasive belts, and abrasive cloth. P Grit is clean and dust-free with sharp, self-sharpening grains, making it ideal for coated abrasives
Precision Lapping & Polishing: Lapping compounds and polishing pastes for precision workpieces, electronic components, and ceramics
Waterjet Cutting Media: Abrasive media for waterjet cutting of oil/gas pipelines and steel components

Q1: Is your company a trading firm or a manufacturing plant? Where are your facilities located?
We are an export-oriented enterprise that integrates manufacturing and sales; we are not an intermediary. Our headquarters—handling international sales, order processing, documentation, and after-sales service—is located in the Liaocheng Economic and Technological Development Zone, serving as the hub for global client relations, order negotiations, and cross-border services. Our production facility is situated in Chiping District, Liaocheng City, and specializes in the R&D, smelting, processing, and testing of white fused alumina, brown fused alumina, and other fused alumina products. This allows us to manage the entire supply chain—from primary production and rigorous quality control to direct export.
Q2: What is your production capacity and supply capability? Can you ensure a stable, long-term supply?
Our production base in Chiping features mature production lines and comprehensive processing equipment, enabling large-scale, continuous manufacturing. We offer a stable supply of our full range of white fused alumina, brown fused alumina, and related fused alumina products. With ample inventory and well-organized production scheduling, we are fully equipped to handle bulk orders, recurring annual orders, and urgent requests during peak seasons, ensuring a reliable, long-term supply for our global clients.
Q3: What are your primary export products, and what are your core offerings?
Our core exports consist of three main series of fused alumina materials: brown fused alumina, white fused alumina, and other fused alumina products. We offer a comprehensive range of specifications and particle sizes that meet various international procurement standards. Brown fused alumina is our flagship product for cost-effective industrial abrasives and refractory raw materials; white fused alumina is designed for high-purity, high-precision grinding and polishing applications; and our broader fused alumina line serves high-end refractory, specialty ceramic, and precision abrasive tool sectors—covering the full spectrum of procurement needs across all market tiers.
Q4: What are the specific applications for these three types of fused alumina, and how should one choose the right product? 1. Brown Fused Alumina: Characterized by high toughness, excellent wear and impact resistance, and a strong price-performance ratio. It is suitable for general industrial applications such as metal sandblasting (rust removal), hardware grinding, the manufacturing of grinding wheels and sandpaper, metallurgical castable refractories, and lining materials for standard industrial furnaces. It serves as a versatile, all-purpose abrasive and refractory raw material.
2. White Fused Alumina: Features high purity, high hardness, and excellent self-sharpening properties, with a pure white appearance free from impurities. It is ideal for high-precision and high-cleanliness applications, including the polishing of precision molds, grinding of aerospace components, finishing of electronic materials, and the production of high-end refractory products and precision ceramics.
3. Fused Alumina (High-Purity/Specialized): Possesses a dense structure, exceptional thermal stability, and high resistance to both heat and corrosion. It serves as a core raw material for high-end, specialized refractories, structural ceramics, precision grinding media, and linings for high-temperature industrial kilns, making it well-suited for demanding, high-performance operating environments.
