Product Overview
Hengtium's fused white aluminum oxide is produced via high-temperature electric arc furnace smelting, followed by crushing, magnetic separation, screening, and classification.
The product features a Mohs hardness of 9.0–9.5, a microhardness of approximately 2000–2200 kg/mm², a true density of about 3.95 g/cm³, and a melting point of around 2250°C, with a maximum service temperature of approximately 1900°C.
Industrial customers requiring high hardness, low impurity levels, and consistent particle size distribution can select the appropriate specifications based on their specific processing requirements.
Why Choose Our White Fused Aluminum Oxide
Hardness up to Mohs 9.5
Fused White Aluminum Oxide possesses high hardness; Hengtium products reach a range of 9.0–9.5 on the Mohs scale, enabling them to withstand heavy processing loads during grinding, lapping, and surface treatment.
01
High-temperature performance up to 1900°C
The product has a melting point of approximately 2250°C and a maximum operating temperature of around 1900°C.
For high-temperature applications such as refractories, you can select the appropriate grade based on your specific operating conditions.
02
Consistent specifications are key
Hengtium processes its products through crushing, magnetic separation, screening, and classification, with a strong focus on controlling particle size and product purity. For manufacturers of grinding wheels and cutting discs, batch consistency means there is no need for frequent adjustments to production formulas.
03
Direct sourcing from the manufacturer
Hengtium has been active in the abrasives industry since 1989; we are not merely traders.
You can communicate directly with us regarding particle size, chemical composition, packaging, order quantities, and customization requirements.
If you already have a Certificate of Analysis (COA) from another supplier, you can send it to us for specification matching.
04
Pricing based on actual requirements
We do not rely on simply offering the lowest price to attract you.
Costs vary depending on particle size, purity, packaging, and order volume.
For full-container loads, long-term contracts, or bulk orders, simply provide the quantity and specifications, and we will offer a factory-direct quote based on your actual needs.
05
Production Process
High-Purity Raw Material → Electric Arc Furnace → Cooling → Crushing → Magnetic Separation → Screening → Classification → Inspection → Packing
During the production of Fused White Aluminum Oxide, we focus on controlling three key areas:
Raw material quality → Minimizing variability at the source
Magnetic separation → Enhancing product purity
Sieving and grading → Ensuring particle size consistency
This ensures that every batch you receive meets the confirmed specifications as closely as possible.
