Module 1

Dear Students
Please explore the web, and answer the following questions:
  1. Which type of aluminium we use for aircraft body and frame?
  2. Find few applications for the following metals:Titanium,Tungsten, chromium, Lithium, molybdenum.
  3. GRP and FRP are composite materials being explained the handouts, find out information about GRC and it applications.

  1. Alloy 7075 has zinc and copper added for ultimate strength, but because of the copper it is very difficult to weld. It anodizes beautifully. 7075 has the best machinability and results in the finest finish.

  10. 1) Pure aluminum is not a strong or hard metal. Aluminum can be alloyed with other elements such as Silicon, magnesium, and copper to make it harder and stronger.

    2) a. The uses for titanium in industry are growing faster than ever before as more and more engineers are discovering it can reduce lifecycle costs across a broad range of equipment and processes.

    b. The hardness and density of tungsten are applied in obtaining heavy metal alloys. A good example is high speed steel, which can contain as much as 18% tungsten.

    c. Stainless steel, the main corrosion-proof metal alloy, is formed when chromium is added to iron in sufficient, usually more than 11% concentration.

    d. In the later years of the 20th century lithium became important as an anode material. Used in lithium-ion batteries because of its high electrochemical potential, a typical cell can generate approximately 3 volts, compared with 2.1 volts for lead/acid or 1.5 volts for zinc-carbon cells.

    e.The ability of molybdenum to withstand extreme temperatures without significantly expanding or softening makes it useful in applications that involve intense heat, including the manufacture of aircraft parts, electrical contacts, industrial motors and filaments.
