150# 180# 220# White Fused Alumina for Wear-Resistant Flooring

White Fused Alumina (WFA) is produced by melting high-purity alumina powder in an electric arc furnace at temperatures above 2000°C.

Key Features：

High Hardness (Mohs 9.0)

Excellent Wear Resistance

High Purity (Al₂O₃ ≥ 99%)

Low Iron Content

High Mechanical Strength

Good Chemical Stability

Long Service Life

These properties make White Fused Alumina one of the best aggregates for high-performance floor hardeners.

Compared with traditional materials such as quartz sand, White Fused Alumina (WFA) offers significantly superior performance in industrial flooring systems. Thanks to its high hardness, excellent wear resistance, and strong mechanical strength, WFA greatly enhances floor durability, impact resistance, and overall service life. These advantages make it an ideal aggregate for heavy-duty applications, including warehouses, manufacturing plants, and logistics centers, where floors are exposed to constant traffic, heavy loads, and mechanical abrasion. By incorporating WFA into floor hardeners, the surface becomes more compact, resistant to wear, and less prone to dusting or surface degradation over time.

In addition, fine grades such as 150#, 180#, and 220# are widely used in surface hardening layers to further improve floor performance. These finer particles help fill micro gaps between larger aggregates, resulting in a denser and smoother surface structure. This not only enhances abrasion resistance but also improves the overall finish and appearance of the floor. As a result, the flooring system achieves both high strength and refined surface quality, meeting the demands of modern industrial environments.

White fused alumina is widely used in a broad range of industrial flooring applications where durability, strength, and long-term performance are critical. It is particularly suitable for industrial workshops, where continuous mechanical operations demand high wear resistance and a dust-free working environment. In automotive manufacturing plants, floors are exposed to constant movement of machinery, tools, and vehicles, requiring materials that can withstand heavy abrasion and impact. Similarly, logistics warehouses and distribution centers experience frequent forklift traffic and high loading intensity, making wear-resistant flooring essential to maintain operational efficiency and safety.

In parking garages, white fused alumina helps improve surface hardness and reduce long-term deterioration caused by vehicle movement and environmental exposure. Airports and hangars also benefit from its excellent load-bearing capacity and resistance to tire friction, ensuring stable performance under heavy aircraft operations. For ports and docks, where floors are subjected to both mechanical stress and harsh environmental conditions such as moisture and corrosion, white fused alumina provides enhanced durability and extended service life.

In demanding environments like steel plants and heavy equipment factories, flooring systems must endure extreme loads, high temperatures, and constant abrasion. White fused alumina, with its high hardness and chemical stability, significantly improves the structural integrity and lifespan of industrial floors in these settings. Overall, it is especially suitable for areas with intensive forklift traffic and heavy load conditions, where maintaining a strong, wear-resistant, and low-maintenance floor surface is essential for long-term industrial performance.



The dry shake floor hardener method is the most widely used for industrial flooring. White fused alumina is evenly spread on concrete during its initial setting stage, then compacted, polished, and cured. This process creates a dense, durable surface with high wear resistance, long service life, and cost efficiency.

White fused alumina is also used in epoxy flooring systems as an aggregate or anti-slip material. It helps improve abrasion resistance, surface strength, and durability, making it suitable for high-performance industrial floors.
