Indium Ingots

Indium is a high purity chemical element with symbol In and atomic number 49

Ingot is the simplest form of indium. Sizes are available from small ‘finger’ ingots, weighing only grams, to large ingots, weighing many kilograms. Ingot is cast into its shape, and is the best way to keep processing costs down if you are using large amounts of indium.
