Introduction

TIN IS A VERSATILE, low-melting point, nontoxic metal that has valuable physical properties. It alloys readily with most other metals, and it forms many useful inorganic and organic chemical compounds because it is amphoteric. It has the largest melting point to boiling point range (from 232 to 2370 °C, or 450 to 4300 °F) of any metal. In conventional metallurgical applications, evaporation from a pot of liquid tin does not occur. Tin is used in a multitude of products, although the amount in which it is present is usually relatively small as a percentage of the total. Most manufacturers use some tin, and it is an essential material in industries such as communications, transportation, agriculture, food processing, and construction.
