Description of Aluminum silicon carbide Al/SiC 

Aluminum silicon carbide has high thermal conductivity, so it can be used to manufacture high thermal conductivity devices such as heat sinks and heat sinks to cope with the heat dissipation needs of high-power electronic devices.
Secondly, aluminum silicon carbide has a low thermal expansion coefficient. It is a material with a low thermal expansion coefficient and good thermal stability, so it can maintain dimensional stability and accuracy when used in high-temperature environments. This property makes aluminum silicon carbide ideal for manufacturing high-temperature instruments and measuring equipment.
In addition, aluminum silicon carbide has high hardness and wear resistance. Its hardness can reach Hv 400-450, so it can be used to manufacture wear-resistant tools such as cutting tools and drills. Because of its high wear resistance and low coefficient of friction, aluminum silicon carbide can also be used to manufacture lubricants and lubrication films to improve lubrication performance and extend the service life of equipment.
In addition, aluminum silicon carbide also has good chemical stability. It is not easy to oxidize and corrode at high temperatures, so it can be used in the chemical industry to manufacture corrosion-resistant devices such as high-temperature reactors and valves. In addition, aluminum silicon carbide can also be used to manufacture high-temperature protective coatings to improve various materials’ high-temperature and corrosion resistance.
Finally, aluminum silicon carbide also has a low density. It has a lower density than pure aluminum, so it can manufacture lightweight components and structural parts to reduce equipment weight and improve mobility. This characteristic makes silicon carbide aluminum one of the best choices for manufacturing lightweight structural materials in aerospace, automotive, and other fields.

Production Method of Aluminum Silicon Carbide Al/SiC

Solid state method
The solid-state method is a common method for preparing aluminum silicon carbide. The method is to mix aluminum powder and silicon carbide powder according to a certain proportion and react at high temperatures to produce silicon aluminum carbide. The silicon aluminum carbide prepared by this method has higher purity and crystallinity, but the production cycle is longer, and the cost is higher.
Fusion method
The melting method uses a high-temperature molten aluminum bath and silicon carbide powder reaction to produce silicon carbide aluminum. The silicon aluminum carbide prepared by this method has low purity and crystallinity, but the production cycle is short, and the yield is high.
Chemical vapor deposition
Chemical vapor deposition (CVD) is the reaction of a compound containing carbon and aluminum elements to produce aluminum silicon carbide under gaseous conditions. The silicon aluminum carbide prepared by this method has high purity and crystallinity, but the production cost is high.
Ion implantation method
The ion implantation method is a kind of ion state of carbon and silicon ions injected into the aluminum matrix, and then through high-temperature treatment, to produce silicon carbide aluminum method. The silicon aluminum carbide prepared by this method has high wear and corrosion resistance characteristics, but the production cost is high.
