Metal tin is mainly used in the manufacture of alloys.
Tin and sulfur compounds - tin sulfide, which is similar in color to gold, is commonly used as a gold pigment.
Tin's modern application is as a solder for the electronics industry. Used in various purities and alloys (often with lead or indium), tin solders have a low melting point, which makes them suitable for bonding materials.
