Copper Granules & Punchings

Copper Granules and Punchings are unalloyed copper at a minimum 99.9% Cu, supplied as free-flowing granules or as punchings left from stamping operations. Both forms exist for the same reason: they melt and dissolve faster than solid copper and can be dosed by weight. Foundries use them for alloy corrections in brass and bronze production, and the chemical industry uses granules where surface area drives the reaction rate. This is a different product from cathode: lower purity, cheaper, and bought for ease of handling, not as refinery feed.
