ABOUT OUR FACTORY

Located in Zhengzhou, our factory has been focused on abrasive materials for over 20 years.
We own two production bases equipped with modern smelting furnaces, precision grading systems, and dust-free micro-powder workshops.
From raw alumina blocks to finished WFA powder, every process is carefully monitored to ensure consistency and purity.

MAIN PRODUCTS

Here are our main types of White Fused Alumina products, each designed for different industrial applications.

Polishing Grade White Fused Alumina

Designed for fine polishing and precision surface finishing, our polishing-grade WFA features ultra-fine grains, high purity, and excellent whiteness. It ensures consistent performance in optical lens polishing, semiconductor substrates, and metal mirror finishing.

Abrasive Grade White Fused Alumina

With sharp edges and superior hardness, the abrasive-grade WFA is ideal for producing bonded and coated abrasives such as grinding wheels, sandpaper, and cutting tools. It provides high cutting efficiency and long service life.

Low Sodium White Fused Alumina

Blasting and Grinding Grade White Fused Alumina

Specially processed for sandblasting and surface preparation, this grade delivers uniform grain shape and stable impact strength. It effectively removes rust, coatings, and burrs while achieving a clean, matte surface finish.

Produced with advanced smelting technology to minimize Na₂O content, our low sodium WFA offers improved high-temperature resistance and chemical stability. It is widely used in advanced refractories, electronic ceramics, and precision casting.
