Silicon carbide grit is a material produced by the reaction of high-purity quartz sand and carbon source (such as coal, charcoal, etc.) at high temperature. According to its size, silicon carbide grit is usually divided into different meshes (such as 46 mesh, 70 mesh, etc.), and each mesh has different characteristics and applications. The size of 46-70 mesh silicon carbide grit between coarse sand and medium sand. It has strong abrasiveness and high high temperature resistance and is suitable for a variety of industrial applications.

Main uses of 46-70 mesh silicon carbide grit

Abrasives and grinding wheels

46-70 mesh silicon carbide grit is widely used in the production of abrasives, grinding wheels and grinding tools due to its excellent hardness and wear resistance.

Ceramics and refractory materials

46-70 mesh silicon carbide grit is widely used in the production of ceramic industry and refractory materials due to its high temperature resistance, hardness and oxidation resistance.

Surface treatment and cleaning

46-70 mesh silicon carbide grit is often used for surface cleaning, rust removal and sandblasting. Due to its high hardness, it can effectively clean the oxide layer, dirt, rust, etc. on the metal surface, and is widely used in construction, shipbuilding, automobile and other industries.

Composite materials

Silicon carbide grit can be used as a reinforcing material and added to metal-based composite materials, ceramic-based composite materials and other composite materials to improve the hardness, wear resistance and high temperature resistance of the material. It is often used for high-performance wear-resistant parts and parts in high-temperature working environments.

Electronic and electrical industries

46-70 mesh silicon carbide grit also has certain applications in the electronics industry, especially in the manufacture of high-temperature and high-power devices. The high thermal conductivity and high temperature resistance of silicon carbide make it an important material for the manufacture of power semiconductors and power switching equipment.

Environmental protection and water treatment

46-70 mesh silicon carbide grit is also used in the fields of water treatment and environmental protection. It can be used as a filter medium to remove suspended particles, impurities, oil stains, etc. in water to improve the cleanliness of water.

Optical and laser applications

Since silicon carbide grit has strong optical absorption and thermal conductivity, some 46-70 mesh silicon carbide grit can be used in heat dissipation and optical devices of laser equipment.

Product Advantages

High Efficiency:

Due to its high hardness and fast cutting speed, it can significantly shorten the processing time during use and improve work efficiency.

Good Economy:

Compared with abrasives such as diamond, it has a lower cost, and has good processing performance in the case of meeting most application requirements, with high cost - effectiveness.

Reusability:

During the use of silicon carbide grit, as the particles break down, new sharp edges will be exposed, so it can be reused, such as in stone tumbling machines, just need to add new coarse - grained abrasives regularly.
