Precision manufacturing, extraordinary polish
Our operating idea — precision manufacturing, extraordinary polish — high-purity, highly consistent, nano-grade precision lapping and polishing solutions for global precision manufacturing.

Zhengzhou Qianyi Abrasive Material Co., Ltd. is a high-tech enterprise combining R&D, production and sales, focused on the innovation and manufacture of high-end ultra-fine abrasives — principally white fused alumina and green silicon carbide.

We produce micron-grade powders for China's semiconductor, piezoelectric crystal, crystal ceramic, magnetic material, precision ceramic, special metal and optical material industries.
The plant sits in the Zhengzhou Superhard Materials Industrial Park in Henan and ships 20,000 tonnes of abrasive materials a year. Multiple production lines produce material to EU FEPA, Japanese JIS and American ANSI standards, and any grade can be customised to a customer's specification.
A full set of testing equipment and a strict quality control system operate under a certified ISO 9001 quality management system. Company standards are benchmarked against JIS — proprietary process control gives more uniform particle size, comparable to well-known Japanese and American brands, and leading domestically.

Efficiency builds the brand. Integrity builds the future. We exist to give precision manufacturers high-purity, highly consistent, nano-grade lapping and polishing solutions, and to help semiconductor, optoelectronic and piezoelectric crystal industries break through technical bottlenecks.
Established in the Zhengzhou Superhard Materials Industrial Park as a producer and seller of white fused alumina, green silicon carbide, single-crystal tabular alumina (PWA) and brown fused alumina.
Multiple production lines brought online, capable of producing to EU FEPA, Japanese JIS and American ANSI standards, with custom grades to customer specification.
A full set of testing equipment and a strict quality control system certified under the ISO 9001 quality management system.
Entered production and sale of single-crystal tabular alumina (PWA) for semiconductor substrate lapping and polishing — hexagonal platelets rather than the equiaxed or spherical grain of conventional abrasives.
20,000 tonnes of abrasive materials sold each year to the semiconductor, piezoelectric crystal, crystal ceramic, magnetic material, precision ceramic, special metal and optical material industries.

In 2018 we moved into single-crystal tabular alumina for semiconductor substrate lapping and polishing. Unlike the equiaxed or spherical grain of traditional abrasives, PWA crystals are hexagonal platelets that lie parallel to the workpiece and slide across it, so they do not scratch randomly.
Grinding pressure is distributed evenly across the platelet face, so grain fracture falls and wear resistance rises sharply — giving the best available material removal rate and surface finish. Test data shows at least 10–20% fewer lapping and polishing passes.
Our operating idea — precision manufacturing, extraordinary polish — high-purity, highly consistent, nano-grade precision lapping and polishing solutions for global precision manufacturing.
