What is aluminum silicon carbide? Aluminum silicon carbide, common grinding stones, grinding wheels and blades are made of silicon carbide. Its hardness is higher than corundum, lower than cubic boron nitride, boron carbide and diamond. Choosing this ceramic material as one of the substrates for our composites, its high modulus and high thermal conductivity are the main factors people value. The silicon carbide used in AlSiC (aluminium silicon carbide) materials is this kind of silicon carbide. Silicon carbide used in the production of composite materials has a very high purity to ensure high thermal conductivity of the material.
Industrial manufacturing of silicon aluminum carbide In industrial manufacturing, silicon carbide particles are first manufactured into silicon carbide preforms (ceramic preforms) in the shape of target finished products. This preform is different from ordinary silicon carbide ceramics, in which many permeable micropores exist. Then, the molten aluminum is hydraulically cast into the micropores under the vacuum environment with special equipment to form the aluminum-silicon carbide composite. The outstanding advantage of aluminum silicon carbide composite material is that it combines the low thermal expansion coefficient of ceramics, the thermal conductivity of pure aluminum, and the strength of cast iron. Its performance is superior to that of tungsten copper, and its price is far lower than that of tungsten copper. It can also be made into large-sized and special-shaped parts that tungsten copper cannot form.
Low temperature oxidation sintered ceramic preform of silicon aluminum carbide The common method of low-temperature oxidation sintering ceramic preform will form a thick silica layer on the surface of silicon carbide, which will seriously affect the thermal conductivity of the product so that the room temperature thermal conductivity of the product cannot exceed 180W/mK (no matter how much it is claimed). However, the silicon dioxide content of our self-developed ceramic preform manufacturing process is only 1/8 of that of the conventional process, and the thermal conductivity of the product exceeds 240W/mK.
Price of aluminum silicon carbide Aluminum silicon carbide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of aluminum silicon carbide. A large amount of large amount will be lower. The price of aluminum silicon carbide can be found on our company's official website.
