Haixu is committed to delivering innovative and sustainable solutions for the green silicon carbide industries of today and tomorrow.
Haixu Abrasives is a manufacturer and supplier of silicon carbide(carborundum) material in China. With over 30 years of experience in the production and sales of black silicon carbide and green silicon carbide, we pride ourselves on serving many customers through long-term, trust-based relationships.
Black silicon carbide (SiC) is the “work-horse” abrasive grade (α-SiC, > 98 % SiC, low SiO₂/Fe). Because it is the hardest man-made mineral except diamond (Mohs 9.2–9.4, Knoop 2480) and yet costs only a few dollars per kilogram, it is consumed in very large volumes for jobs that simply need cheap, fast cutting and where the dark colour or slight friability is not a problem. The main uses are:
Black SiC F600 polishing powder (particle size about 13–14 μm) is a high-performance fine silicon carbide powder for jade tumbling grinding. It is especially suitable for the finishing and lightening in the jade processing process. It can balance processing efficiency and surface finish, and is widely used in the batch tumbling of various jade materials such as jadeite, nephrite, and agate.
AlN(Aluminum Nitride) ceramic PCB substrate is a high-performance electronic substrate material that uses aluminum nitride ceramic as the core insulating and heat-dissipating base, combined with metal conductive layers (usually copper) to form a printed circuit board (PCB) for high-power, high-frequency electronic devices. Green SiC powder for polishing AlN ceramic surface can acheive a excellent surface toughness.
The goals we set for our products and services are to improve our clients’ products’ performance, improve the efficiency of their manufacturing processes, or extend the lifetime of their equipment. We intend to achieve this through our “Six Key Values”.
