Many domestic industry giants and Fortune 500 companies have established strategic partnerships and continue to provide high-quality products, technologies and services to global customers.
Non-metallic abrasives do not contain metal components, so no metal contamination is introduced during the processing. This is critical for applications that require the purity of the material or avoid metal contamination.
There are many types of non-metallic abrasives, including aluminum oxide, silicon carbide, etc. Each material has different hardness, density and chemical properties, which can meet different processing needs, from rough grinding to fine polishing.
Non-metallic abrasives are very stable chemically and are suitable for use in chemically active environments. They will not react adversely with the processing materials.
Some non-metallic abrasives are natural materials, which have less impact on the environment after use, are easy to handle and recycle, and meet the requirements of sustainable development.
