1. -Characteristics -How is it obtained? -Alloys -Uses Marina Polo David González Alberto Muro Arancha Neira

2. - Silvery-white metal - Non-magnetic - Resistant to corrosion - Durable - Soft - Ductile - Malleable - Expensive, but can last long time when properly maintained

3. Tin is mainly obtained from the mineral cassiterite, where it occurs as tin dioxide, SnO 2. It is obtained by the reduction with carbon at elevated temperatures. The purity of the product depending, to a major degree, on the amount and kind of impurities associated with the cassiterite subjected to the reduction treatment. A certain amount of purification of the reduced tin can be effected by liquation and boiling, tossing, or poling, but the production of tin.

4. BRONZE: Bronze is an alloy consisting primarily of copper, usually with tin. It is hard and tough. TIN-PLATES: Thin steel sheet with a covering of tin applied either by stocking in molten metal or by electrolytic deposition.

5. -About half of all tin that is produced is used for soldering. This is usually used for joining electric circuits. -Tin is used for coating lead, zinc of steel to prevent corrosion. -It is used in many specialized alloys including bronze. -Tin has also been used to create decorative house wares. -Molten glass used in the production of windows is often floated on top of molten tin to create a flat surface. -Tin, together with lead, is also used in the metal pipes of the pipe organ.
