La importancia y los usos del estaño

Tin, with the symbol SN and atomic number 50, is a non-precious yet significant metal. Known for its corrosion resistance and malleability, tin has been used since the Bronze Age. It is crucial in soldering, often alloyed with lead, and as a coating for metals to prevent corrosion. Tin is a key component in bronze, making up about 12% of the alloy, and was historically used in weapons and art. Pewter, another tin alloy, was used in ancient Egypt for pottery and later for tableware. Today, tin is used in various applications, including tinning steel and as a mordant in fabric dyeing.
