タイトルまたは説明

Silver-white metal, soft, with good ductility. Melting point **2 ℃, density of 7.*9g / cm3. Non-toxic

Tin is a soft, silvery white metal but it with lead, zinc is very similar, but it looks to be more brighter. Its hardness is relatively low, you can cut it with a knife. It has good ductility, especially at a temperature of **0 ℃, can develop into a very thin foil, the thickness can be as thin as 0.*4 mm or less.

Tin is also a low melting point metal, its melting point is only **2 ℃, so long as it can be with melted candle flame like quicksilver fluidity as well liquid.

Pure tin has a strange performance: When the tin bars and tin plate bending, will be issued a special cries like a popping sound. This sound is emitted by the friction between crystals caused. When the crystal deformation, will produce such friction. The strange thing is, if for tin alloy, in the deformation, but does not issue such a cry. Therefore, it is often based on the characteristics of tin to identify whether it was a piece of metal tin.

The main purpose of editing

Can be used as a coating material has a very wide range of uses in food, machinery, electronics, automotive, aerospace and other industrial sectors. In the float glass production, the molten glass floats on the surface of the molten tin pool is cooled and solidified.

Specifications

Tin reserves

China's tin reserves accounted for *8% of the world ranking No. 1, tin and tungsten, antimony, rare earth and known as China's four strategic resources, it is one of the few Chinese can have pricing power of strategic resources. Tin shares (**0,**0) tin reserves account for about *5% of Chinese, *0% of the world. Tin shares since listing six years expanding possession of resources, an annual increase of reserves exceeds the amount mined tin reserves has not decreased. Tin concentrate production for ***7 is expected to *7,**0 tons (about 4.5 percent of global tin concentrate production), refined tin production is estimated at *4,**0 tons (accounting for *5% of global output of refined tin in the world and the first one, the next 2 in controllable production capacity can reach *0,**0 tons accounting for over *0% global share), the current self-sufficiency rate of tin concentrates approximately *1%

Application

1. Mainly used for electronic industry soldering

2. In the float glass production , molten glass floating on molten tin pool surface is easily to be cooled and solidified.

3. Widely used as a coating material in High-precision electronic products, and other requirements of precision welding products, welding products, general electronics, food industry packaging, automotive and electrical industry, and high temperature resistant products.
