Sold by the ounce. Quantity 1 = one 1 oz (28.35 g) puck of 99.99% pure (4N) indium metal.
99.99% Pure Indium Metal – 1 oz (4N)
Rock Shot Products offers high-purity 99.99% pure (4N) indium metal in a convenient 1 oz size for electronics, specialty soldering, thermal applications, laboratory research, alloy manufacturing, collecting, and other specialty uses.
Each piece is cast into a compact round 1 oz puck and stamped “RSP” for Rock Shot Products identification.
The 1 oz size provides an economical way to purchase high-purity indium for smaller projects without purchasing a full kilogram.

Why Indium?
Indium is an exceptionally soft and malleable metal with a relatively low melting point of approximately 156.6°C (313.9°F).
Its combination of softness, low melting temperature, thermal properties, and ability to conform closely to surfaces makes indium useful for specialized electronics, soldering, sealing, thermal-management, coating, alloying, and research applications.
Convenient 1 oz Size
The Rock Shot Products 1 oz puck provides a convenient way to purchase high-purity indium in smaller quantities.
The compact puck format is easy to handle, store, melt, or use as an alloying addition.
Quantity 1 = 1 oz
Quantity 2 = 2 oz
Quantity 5 = 5 oz
Simply select the quantity corresponding to the number of ounces you need.
RSP Cast Puck
Each puck is cast and stamped “RSP” for Rock Shot Products identification.
Indium is an extremely soft metal and can be scratched, dented, bent, or marked relatively easily. Surface finish, dimensions, shape, and minor handling marks may vary slightly from piece to piece. These cosmetic variations do not affect the specified weight or purity.
