  • Metal Extraction Lab Report

    1196 Words  | 5 Pages

    Many ores contain valuable metals that can be extracted and used for construction, infrastructure, and more. Extraction is a technique that allows large pieces of ore to be broken down into pieces small enough for the valuable metal to be removed. Metal extraction is extremely important technique because the metals inside ores have special properties such as strength, durability, malleability, and ductility. 1 Iron, copper, aluminum are a few examples of widely used metals that are commonly extracted

  • Advantages And Disadvantages Of A Metal Matrix Composite

    722 Words  | 3 Pages

    A metal matrix composite is composite material which comprises two constituent parts, one of which is a metal and the other material may be a different material such as a ceramic or organic compound. This is called a hybrid composite. They are metals with less density and high specific properties such as strength and stiffness. They exhibit properties which are hard to obtain from a single material. One material acts as a matrix and other acts as reinforcement. It is possible to tailor their properties
