This metal was inaccessible and expensive, so products made from it are rare among Roman and Greek antiquities. Tin is mentioned in the Bible, the Fourth Book of Moses. Tin is (along with copper) one of the components of tin bronze, invented at the end or middle of the 3rd millennium BC. e. Since bronze was the most durable metal and alloy known at the time, tin was a "strategic metal" throughout the "Bronze Age" for over 2000 years. </div> <div> Lovo is mainly used as a safe, non-toxic, corrosion-resistant coating in pure form or in alloys with other metals. The main industrial uses of tin are in tinplate (tinned iron) for the manufacture of food containers, in solders for electronics, in house piping, in bearing alloys, and in coatings of tin and its alloys. The most important tin alloy is bronze (with copper). </div> <div>   </div>
