History
With tin alloys, mankind has known for a very long time — since the Bronze Age and its popularity in the industry to this day remains at a high level. The first metallurgical experiments with pure tin took place more than 4 thousand years BC: in the territories of modern South Armenia and Northern Iran. In the past, tin was often used to make metal dishes. However, at negative temperatures it becomes brittle. It is believed that it was the tin elements of the Napoleonic army’s form that became one of the reasons for its defeat in the Russian campaign of 1812, as clothing, a number of household items and weapon parts became irreversibly damaged in severe frosts. Today, this metal is widely used in the food industry, as an alloying element, and also acts as an obligatory component of almost all solders and antifriction alloys.
Technical specifications
Tin is stable only at temperatures up to 130 ° C, below a temperature of minus 33 ° C it turns into a powder. This phenomenon was called «tin plague», for the control of which titanium was additionally injected into the tin alloy (dangerous, however, for human health). At a temperature above 150 ° C, this metal begins to be highly oxidized in ordinary air. Supplier Avlob offers to buy tin alloys at a bargain price. The price is the best in this segment of rental.
