Tin's Applications: Solder Alone Is Half the Market
Just over half of all tin becomes solder, joining nearly every electronic connection on Earth, with tin chemicals and tinplate the next two largest uses.
Solder
Joining electronic connections, using the thermal cycling mechanics covered on the mechanics page, the dominant single use.
Tin chemicals
Stabilisers, catalysts, and specialty chemical compounds.
Tinplate
Thin tin coating on steel, covered on steel's own pages, for food and beverage cans, preventing corrosion without the weight of a thicker coating.
Lead-acid batteries
A small alloying role in battery grid construction.
The breakdown
Because solder so thoroughly dominates demand, tin’s market is, in practice, a direct derivative of global electronics production volumes, tying its fortunes to consumer electronics, telecommunications equipment, and industrial controls manufacturing cycles more than to any construction or transport trend covered elsewhere in this series.
