The non-ferrous part of Liberty's business is fast growing component and includes the following metals (both physical and on paper):
Nickel (Ni) - Nickel is a strong, ductile, malleable metal, resistant to corrosion and a poor conductor of both heat and electricity. 55% of the total supply of the world’s nickel is supplied by just 5 countries and 60% of the world’s output is used in the stainless steel industry.
Copper (Cu) - Copper is a reddish brown metal, considered to be the oldest known commodity that has a bearing on the worldwide economy. Copper does not corrode and is a highly conductive and malleable metal. The main business market for copper is in the construction industry for use in electrical wiring and plumbing. In some countries copper is also used for coinage production.
Zinc (Zn) - Zinc is a blue-white metal and after steel, aluminium and copper, it is the 4th most used metal in the world. It is highly resistant to corrosion, particularly from the atmosphere, is hard and brittle, as well as moderately conductive. Zinc is used as a coating for other metals and mainly used in construction and automotive industries.
Tin (Sn) - Tin a silvery-white metal. It is highly resistant to corrosion and low on toxicity. This prevents tap water, salt water or distilled water from corroding tin, which allows it to have numerous applications for which other metals would be unsuitable. Tin does not oxidise on contact with the atmosphere, which makes it ideal for coating of other metals.
