Titanium carbide (TiC) is a titanium compound that is used for it hardness. TiC is used to produce cutting tools. The strength of titanium avails it to be used to cut and to engrave other metals which are not as hard as titanium. Titanium nitride (TiN) is a titanium compound that is used for its color. TiN is used in jewerly and as a finish on glass because it is a striking yellow color.
Aluminum is a generally popular metal because it does not rust and it resists wear from weather and chemicals. (Bowman, 391) Aluminum is an element. Its atomic number is thirteen and its atomic weight is usually twenty-seven. Pure aluminum melts at 660.2ºC and boils at 2500ºC. Its density is 2.7 grams per cube centimeter.
Shell part is made of phosphorus bronze which is an alloy of copper. It has very high strength and toughness and also good electrical and thermal conductivity. Nickel and brass is also used because of their high strength. Resistance to corrosion also makes it perfect for use. Silver is also very good material for shell but it is very
Copper doesn’t break when hammered, stamped, forged, or spun into unusual shapes. Copper can be shaped either in a hot or cold shape. Besides being easily shaped, Copper is dutiable. Ductility is the ability to be drawn into thin wires without breaking. When heated, Copper becomes very ... ... middle of paper ... ...s its red color from the iron.
Aluminum, or Aluminium, as the British call it is considered one of many “poor” metals. Being very malleable, it can be made into any shape. It is often pressed into thick aluminum plates of armor for tanks or into thin pieces to make wrappers and foil. Aluminum is extremely popular because it does not rust and can withstand all kinds of chemicals and weather conditions. Aluminum is number thirteen on the periodic table and it’s atomic weight is twenty seven.
Stainless steel is highly resistant to corrosion, with its strength it is widely used in construction, storage and chemical industries. On the other hand due to the its high quality stainless steel’s capital is high, so usually crude steel is favoured. (New 2010) The second largest usage of nickel is electro plating.

Leaded brass rods are widely used in many applications such as decoration and architecture for electrical and structural systems. Many parts, for example, screws, nuts, bolts, and fittings, are produced by automatic turning operations . Some alloying elements sometimes added to impart special characteristics to brass. Lead, which is insoluble in copper alloys, used to improve machinability of leaded brass. However, Pb and Bi or other elements that are used to improve the machinability often deteriorate the low and high temperature ductility of brass .
Copper and copper alloys, such as bronze, brass, leaded brass are commonly used in friction parts of machines, as bearing liners, bushings, and water with gas fittings. Properties such as high strength and ductility, fatigue strength, wear resistance and machinability are necessary for these materials. Obtaining such properties is possible by creating submicrocrystalline and nanocrystalline structures in the materials . The most common copper alloys are the brasses for which zinc, as a substitutional impurity, is the superior alloying element. Some of the common brasses are yellow, naval, and cartridge brass and gilding metal.
(www.encyclopedia.com/articles:2000). Many alloys of iron are resistant to corrosion. Stainless steels are alloys of iron with such metals as chromium and nickel; they do not corrode because the added metals help form a hard, adherent oxide coating that resists further attack. The iron hulls of ships can be protected against rusting by attaching magnesium strips to the underside of the vessel. An electric current is generated, with the magnesium and iron acting as electrodes and seawater acting as the electrolyte.
The atomic weight of aluminum is 26.9815; the element melts at 660° C (1220° F), boils at 2467° C (4473° F), and has a specific gravity of 2.7. Aluminum is a strongly electropositive metal and extremely reactive. In contact with air, aluminum rapidly becomes covered with a tough, transparent layer of aluminum oxide that resists further corrosive action. For this reason, materials made of aluminum do not tarnish or rust. The metal reduces many other metallic compounds to their base metals.
