What is aluminum silicon carbide? Aluminum silicon carbide is a particle-reinforced metal matrix material that uses aluminum alloy as the matrix and silicon carbide particles as the reinforcement to form a multi-component composite material with the obvious interface. It has comprehensive, superior properties that a single metal does not have. Al-based silicon carbide has the advantages of high toughness, high plasticity, high hardness and high modulus of silicon carbide particles, high thermal conductivity, and adjustable thermal expansion coefficient. It is a new generation of electronic packaging material and plays a great role in the electronic field.
Application of silicon aluminum carbide in aerospace optical instrument materials Compared with the structural aluminum-based silicon carbide with low volume fraction, the functional characteristics of aluminum-based silicon carbide with medium volume fraction (35%~45%) of optical instrument grade are more prominent; that is, it not only has a specific stiffness twice higher than that of aluminum alloy and titanium alloy but also has a low thermal expansion coefficient close to that of beryllium and steel and dimensional stability better than that of beryllium. Therefore, this composite material can be used as inertia instead of beryllium and is known as "the third generation of aerospace inertial device material."
Application of aluminum silicon carbide in other fields Although aluminum-based silicon carbide is the third generation of electronic packaging material and plays a vital role in electronic packaging, its processing performance is particularly poor. The processing difficulty of aluminum-based silicon carbide is great, mainly due to its hardness. Junjie ceramics can process hard and brittle materials with high speed and precision. Silicon carbide, also known as carborundum, is an extremely hard material with a hardness second only to diamond. As a composite material of aluminum particles and silicon carbide, aluminum-based silicon carbide's hardness increases with the silicon carbide content. The tool will be seriously worn when cutting, resulting in higher processing costs. Therefore, choosing a tool with a smooth, sharp edge and high hardness is best. PCD tool is a good choice. In addition, processing equipment with strong rigidity shall be selected to prevent the spindle from jumping.
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.
