Brown Fused Alumina, produced by the fusion of bauxite in electric arc furnaces at temperatures above 2000°C, is a premier material for abrasives, refractories, and surface preparation industries. Its unique crystalline structure and exceptional hardness, scoring 9 on the Mohs scale, ensure longevity and efficiency in demanding applications. Italian manufacturers focus on consistent quality, precise sizing, and tailored packaging—making their products ideal for international buyers seeking reliability and technical excellence.
- Value in grinding, sanding, and metal finishing.
- Essential for high-temperature refractory linings.
- Widely used in surface cleaning and coating applications.
Italy's advanced manufacturing sector enables Brown Fused Alumina suppliers to maintain global competitiveness, with extensive expertise and supply chain agility.
General Abrasivi S.r.l. specializes in semi-friable Brown Fused Alumina, serving surface preparation, abrasive production, and refractory material markets. Their competitive edge lies in ISO-certified manufacturing, custom logistics for OEM partnerships, and technical consistency.
W Abrasives Italy provides high-density, non-metallic abrasives suited for precise surface finishing and cleaning across multiple sectors, including medical devices and advanced engineering.

As a division of a global minerals leader, LKAB Minerals Italy offers both Brown and White Fused Alumina in a variety of grades. Their emphasis on traceability, high purity (approaching 95% alumina), and bulk shipping supports large-scale industrial projects and foreign OEMs.
DOMILL Abrasive combines meticulous grading standards with robust quality controls to supply Italian and international markets with premium Brown Fused Alumina. Their products are widely used in grinding wheel manufacture, industrial polishing, and refractory production.
Saint-Gobain's Italian branch delivers engineered abrasives with customizable granulometry and superior chemical purity, supporting automotive, aerospace, and electronics industries. Their adaptable supply and commitment to quality assurance ensure compliance with strict engineering requirements.
The production of Brown Fused Alumina consists of several critical stages:
High-grade bauxite, often mixed with coke or small amounts of iron filings, provides the necessary aluminum oxide content. The purity and sizing of bauxite are carefully controlled, with Al₂O₃ content exceeding 76% and stringent limits on impurities such as Fe₂O₃ and TiO₂. Additives help ensure optimal grain toughness.
Raw materials are smelted in an electric arc furnace at temperatures exceeding 2000°C. During this process, iron impurities settle at the base, carbon rises to the surface, and high-purity alumina crystallizes centrally. Careful management of furnace parameters ensures strong, uniformly fused grains.
The fused alumina mass is cooled, solidified into blocks, and crushed. Screening follows, separating particles into specific grain sizes aligned with industrial needs—from coarse for blasting to ultra-fine for polishing applications. Advanced screening technology is employed to align granule distribution with global standards like FEPA and ANSI.
Brown Fused Alumina is cleaned using high-intensity magnetic separators to remove iron and other metallic impurities. Further washing, sometimes with acid treatments, removes dust and unwanted particulates, enhancing product clarity and performance.
Final refinements include drying, additional calcination for special grades, and precise packaging to ensure product integrity. Bulk bags, paper sacks, and customized containers allow suppliers to meet diverse buyer specifications.
| Compound | Brown Fused Alumina | White Fused Alumina |
|---|---|---|
| Al₂O₃ [%] | 95.38 | 99.60 |
| SiO₂ [%] | 0.98 | 0.08 |
| TiO₂ [%] | 2.55 | 0.01 |
| Fe₂O₃ [%] | 0.16 | 0.02 |
Higher alumina content and low iron impurity ensure superior abrasion resistance and thermal stability, while strict particle sizing delivers consistent results across applications.
- Hardness: Mohs 9; nearly as hard as diamond.
- Density: Supports precision grinding and cut quality.
- Thermal Stability: Withstands aggressive industrial temperatures and chemical exposure.
- Crystal Structure: Angular, giving excellent cutting and finishing capabilities.
Brown Fused Alumina's toughness makes it essential for grinding wheels, sandpaper, and polishing compounds. Quality consistency and custom grading enable brand owners and manufacturers to optimize product performance and longevity.
With high-temperature tolerance and low reactivity, Brown Fused Alumina is a cornerstone in furnace linings, foundry molds, and specialty tiles. Italian suppliers' reliability ensures supply continuity for steel mills and ceramics producers.
