Tin foil, tape

History

Tin began to mine and smelt the ancient Sumerians and Chinese in pre-biblical times. However, for many centuries, the tin remained a rare and expensive metal, almost as valuable as silver. Tin decoration almost never find in the excavation. The demand for tin began to increase in the ancient times, from the early bronze age. This metal along with copper has become the basis of bronze, invented in the third Millennium BC, the Lion’s share of bronze until the early twentieth century was the production of weapons. In ancient times it was bronze swords and other piercing and slashing weapons, and later bronze cannons and cannonballs. Tin was a «strategic material» for more than two thousand years. The Latin name of this metal stannum is derived from the Sanskrit word «strong, steadfast». A thousand years ago the so-called alloy of lead and silver. Pure tin has been able to identify only alchemists in the IV century.

General characteristics

Tin is the 50th element of the periodic system of Mendeleev, where indicated by the symbol Sn. The atomic weight of 118.7, the weight of 5,846 g/cm³. Has a low temperature plavleniya about 231,9°C; t° boiling point 2620 °C. Excellent conductor of current. at 20 °C has a resistance 0,115 Ohm·mm²/m.

Dignity

Tin refers to readily available long-used metals. Different corrosion resistant, low melting point, low-cost production technology, excellent manufacturability. It is very flexible, biologically inert metal with excellent anti-friction properties. It is easily punched, drilled, bent, cut, rolled into the thin foil. After recycling goes to recycling and use. Numerous advantages make it very popular today. Price of 1 kg of Sn depends on the degree of purification. Technical tin worth 18−19 dollars for 1 kg, cleaned oxide SnO₂ — $ 25, single-crystal high-purity tin 210 dollars for 1 kg.

Disadvantages

Low strength does not allow of tin reference part.

Application

• Corrosion-resistant, safe for health, coating tinplate — tin-plated hardware — excellent durable packaging, which produces food containers, light and durable containers for water.
• It is indispensable in the composition of the solders, antifriction alloys, to facilitate the work of mobile nodes.
• Tin enters into the composition of many alloys. The most famous of them is bronze. Less well-known alloy — computer many years, used for the production of pottery. Alloy with niobium has superconducting properties are indispensable in modern electrical engineering. Additives of tin, make titanium alloys more technologically advanced. The alloy Sn+Zr is temperature-resistant and oxidation resistance when heated, it t° melting point 2000°C
• Manganese-tin, mercury-tin, lead-tin batteries are much more energy-intensive than pure lead at low internal resistance.
• The dioxide SnO₂ is used for polishing optical lenses.
• A mixture of tin salts has long dyed wool in yellow.
