Use of the metals and alloys

1
Use of the metals and alloys

• Metal
• Any of a class of substances characterized by
  high electrical and thermal conductivity as well
  as by malleability,ductility,and high
  reflectivity of a light.
• Alloys
• Metallic substance composed of two or more
  elements, as either a compound or a solution. The
  components of alloys are ordinarily themselves
  metals, though carbon,a nonmetal,is an essential
  constituent of steel.

2
Metal Iron ( Fe )

• Chemical element, metal of Group VIII of the
  periodic table , the most used and cheapest
  metal.
• Characteristics
• Strong,(especially in form of steel.)
• Malleable
• Cheap in price.

3
Use of Iron

• We use iron to make ship and bridge,because it is
  hard ,cheap in price,malleable.

4
Alloy steel

• An alloy of iron and carbon in which the carbon
  content amounts to about 2 or less.the addition
  of this tiny amount of carbon results in a
  substance that exhibits great strength,
  hardness,and other valuable mechanical
  properties,and these,together with its low
  manufacturing cost and abundant source materials

5
Use of steel

• The powerful saw
• Its made of hard steel.
• It is hard in enough to cut other metal.

6

• Use to make the railway lines,because its is hard
  enough to absorb the weight from train.
