What is aluminum silicon carbide? Like aluminum, silicon carbide ceramic material is well known, commonly known as steel sand. Common grindstones, grinding wheels, and cutting blades are made of silicon carbide. Its hardness is higher than corundum's and inferior to cubic boron nitride, boron carbide, and diamond. This ceramic material is selected as one of the base materials of our composite materials, and its high modulus and high thermal conductivity are the main factors that people value. Silicon carbide used in AlSiC (aluminum silicon carbide) materials is this kind of silicon carbide. The purity of silicon carbide used in the production of composite materials is very high to ensure the material's high thermal conductivity.
Performance characteristics of silicon aluminum carbide The specific stiffness (stiffness divided by density) of AlSiC is the highest of all electronic materials: 3 times aluminum, 5 times W-Cu and Kovar, and 25 times copper. In addition, the seismic resistance of AlSiC is better than that of ceramics, so it is the preferred material in harsh environments (such as aerospace, automotive and other fields). AlSiC can be processed in large quantities, but the processing technology depends on the content of silicon carbide, which an electric spark, diamond, laser, etc., can process. AlSiC can be plated with nickel, gold, tin, etc., and the surface can also be anodized. The metalized ceramic substrate can be brazed to the AlSiC substrate, and the printed circuit board core can be bonded to AlSiC with adhesive and resin. AlSiC itself has good air tightness. However, the airtightness after packaging with metal or ceramic depends on the proper coating and welding. The physical and mechanical properties of AlSiC are isotropic.
Material significance of silicon aluminum carbide The successful development of AlSiC packaging materials marks that Chinese enterprises are no longer simple blue-collar processors in the packaging field but have their packaging leading products with independent technology core, filling the domestic gap, which is a huge technological progress in the packaging field; The use of AlSiC produced by Xi'an Mingke Microelectronic Materials Co., Ltd. is to support national industry and contribute to the localization of relevant fields. The superior performance makes AlSiC have a broader performance than W-Cu, Mo, BeO, Kovar, Mo-Cu, AlN, AlSi, Al2O3, and other existing packaging materials, and AlSiC has a wider use space than W-Cu, Mo, BeO, Kovar, Mo-Cu, AlN, AlSi, Al2O3, and other existing packaging materials.
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.
