Alloys

=**ALLOYS**= 3-5 characteristics

4.Today the most important are the alloy steels, which have a wide range of special properties including hardness, toughness, corrosion resistance,magnetizability,and workability. Steel is most expensive, also is not safe in food. THEY CAN BE VERY HAZARDOUS!
 * 1) An alloy is a metal composed of more than one element.
 * 2) Engineering alloys include the cast-irons and steels,aluminum alloys, magnesium alloys,titanium alloys,nickel alloys,zinc alloys and copper alloys.
 * 3) A homogeneous mixture or slid of two or more occupying interstital positions between the atoms of the other: Bass is an alloy of zinc and copper.
