●Custom special mesh sizes available

Applicable Scenarios

 ‑ Linings for blast furnaces & hot‑blast stoves ‑ Ceramic kilns ‑ Glass melting furnaces ‑ Linings for petrochemical cracking furnaces ‑ Electronic ceramic saggers ‑ Aggregates and coatings for precision casting ‑ Catalyst carriers 

White Fused Alumina

White Fused Alumina (international code: WA) is produced with high‑purity industrial alumina powder as raw material. It undergoes melting at temperatures above 2000°C in an electric arc furnace, followed by cooling and crystallization. Afterwards, it is processed through crushing & shaping, magnetic iron‑removal and size classification. 

It features dense crystals and pure white colour, with high alumina content and extremely low impurities. Compared with brown fused alumina, it has slightly higher hardness yet lower toughness. Thanks to good self‑sharpening property and low grinding heat generation, it is the preferred abrasive for machining high‑hardness steel and high‑end surface treatment.

Product Features  

★High alumina purity  ★High refractoriness    ★High refractoriness  

★High hardness     ★Excellent wear resistance   ★Superior slag‑erosion resistance

 Specifications

● Grain sizes from 24# to 1200#, plus micro‑powders 

● Custom special grit sizes available

 Applicable Scenarios

‑ Bonded and coated abrasives ‑ Sandblasting and surface treatment ‑ Sand for precision casting ‑ High‑grade refractory castables ‑ Ultra‑fine grinding for electronics and semiconductors ‑ Water‑treatment filter media ‑ Insulating and chemical fillers
