Tin’s biggest use is in semiconductors. Over 50% of the worlds tin is used as an electronic solder for joining circuit boards. Demand of semiconductor is surging and the global semiconductor market is projected to double in the next five years (from approximately $400 billion in 2021 to $803 billion in 2028). The strong growth is driven by demand for emerging technologies such as electric and autonomous vehicles, (revenue from this segment alone is growing at a five year CAGR of 21%), artificial intelligence, 5G, internet of things as well as consumer electronics.
Tin also has a big role to play in the growth of solar PV, with solder ribbon used to join solar panels. That represented 7500t of tin use in 2016, with the International Tin Association predicting the market will double by 2030 as the usage of solar renewable energy rises.
Tin is also used as a chemical in making flat glass panels, stabilises PVC and plastics, plating for steel cans and is contained in both lead-acid and lithium ion batteries. Tin essentially turbo charges lithium. The current best technologies for lithium ion batteries involve tin anodes, which enable significantly faster recharge than any other technology.
