4 Inch FC161 Silicon Carbide Fiber Disc

Features and advantages：
High hardness and strong grinding force: Silicon carbide itself has high hardness, with a Mohs hardness of 9.55, second only to diamond. The steel paper diaphragm using it as an abrasive can effectively grind a variety of materials with high grinding efficiency.
Good wear resistance: It has good wear resistance and can maintain a stable grinding effect during long-term use. It has a long service life and has a low replacement frequency compared to ordinary grinding discs, which can reduce the cost of use.

Good heat resistance: It can be ground in high temperature environment, and is not prone to material deformation and performance degradation due to heat, and can adapt to some processing scenarios with temperature requirements.
Excellent matrix performance: With steel paper as the matrix, it has high strength, good toughness, and good rigidity. It is not easy to break under high-speed rotation and high load. It is safe and reliable to use. At the same time, it also has a certain elasticity and can better fit the surface of workpieces of different shapes.

Grit size: Common mesh sizes of silicon carbide steel paper grinding discs include 24#, 36#, 40#, 50#, 60#, 80#, 100#, 120#, etc.

Size: Common sizes of fiberglass abrasive discs are 4 inches (100MM), 5 inches (125MM), 6 inches (150MM), 7 inches (180MM), etc. Of course, there may be some special customized sizes, which should be determined according to the actual product.

Application scenarios：
Metal processing field: It can be used for surface rust removal, paint removal, burr removal, welding spot and weld grinding and polishing of metal materials such as steel, stainless steel, aluminum alloy, etc., which can make the metal surface reach a high degree of finish.
Wood processing industry: Grinding furniture, wood products, etc. can make the wood surface smooth and flat, which is convenient for subsequent painting, finishing and other processes, and improves the appearance quality and feel of wood products.
Other industries: In shipbuilding, aviation, locomotives, bridges, boilers, cast aluminum, casting, yachts, box manufacturing and other industries, various complex surfaces of metal and non-metal materials are polished to meet different process requirements.
