Description: SupremEX S-225F is a non-beryllium metal matrix composite that consists of silicon carbide at 25% volume fraction in a 2124 aluminum matrix, and has a closely matched coefficient of thermal expansion (CTE) to that of AlBeMet® over the standard tactical
Aluminum (Al) - silicon carbide (SiC) metal matrix composite (MMC) brake rotors have been investigated for lightweight vehicular appliions but have not widely been utilized due to issues with uniformity of distribution of SiC particulates, residual porosity, formation of undesirable phases such as aluminum carbide, and high temperatures incurred during braking that degrade the rotor’s
These materials use a metal such as aluminum as the matrix, and reinforce it with fibers such as silicon carbide. The space era has increased the demand for MMCs that possess high specific stiffness and near-zero coefficient of thermal expansion (CTE).

These variations can be referred to the fact that dimensional stability of composite materials depends strictly on Young’s modulus. According to the previous researches [16–18], at constant volume fraction, the role of nanosized silicon carbide on Young’s modulus of aluminum matrix is much higher than that of microsized; therefore, change in length of aluminum should be restricted in the
AlSiC, pronounced "alsick", is a metal matrix composite consisting of aluminium matrix with silicon carbide particles. It has high thermal conductivity (180–200 W/m K), and its thermal expansion can be adjusted to match other materials, e.g. silicon and gallium arsenide chips and various ceramics..

2017/8/18· The composite was fabried by stir casting route by using aluminum 7075 alloy as the matrix and 10% by weight silicon carbide as reinforced material. Results have revealed that the value of coefficient of friction is found to be maximum in case of inert condition in matrix alloy at sliding speed 3.77 m/s and minimum in case of lubried condition in composite at sliding speed 3.14 m/s.
For instance, aluminum can be reinforced with boron, carbon, silicon carbide, alumina, or graphite to create a composite that is 30% to 40% stronger and more rigid than barebones aluminum. Metal
Metal Matrix Composite A composite of two or more materials wherein the metal provides a continuous structure that contains the other constituents of the composite. For AlSiC, aluminum is the metal matrix in which the SiC particles are suspended.
