Metals

Question 1

Non ferrous metals

Answer 1

Metals that do not contain iron (ferrite)

Question 2

Ferrous alloys

Answer 2

A mixture of two or more metals - at least one of which contains iron (ferrite) and carbon

Question 3

Non ferrous alloys

Answer 3

Mixture of two or more metals, none of which contain iron (ferrite)

Question 4

Iron:

Answer 4

Iron (ferrite) is converted from its ore by heating. The slag (resulting impurities) are removed from the furnace leaving a soft grayish metal once cooled. Iron is rarely used without combining with carbon; this gives it greater strength. The result of this combination is steel. (Can be enhanced with other alloys)

Question 5

Crystal

Answer 5

The main building block of most, if not all metals

Question 6

Steel

Answer 6

A mixture of carbon and iron. The amount of carbon present in the material determines the materials initial strength. Alloying with other metals enables specific properties such as strength, toughness and resistance to corrosion to be enhanced.

Question 7

Carbon

Answer 7

Is an element found in a range of materials. Carbon is found in most organic materials; materials such as coal and diamond are made up purely of carbon. The amount of carbon in steel has the effect of increasing strength and hardness.

Question 8

Copper

Answer 8

Brownish in colour, can be alloyed with zinc to produce brass or with tin to produce bronze.

Question 9

Bauxite

Answer 9

The most common metal in the earths crust - can be made into aluminium using processes such as electrolysis

Question 10

Ferrous metals

Answer 10

Metals that contain iron (ferrite) and carbon
