What is Bismuth Metal?
Bismuth is a silvery metal with a slight reddish hue, brittle and stable at room temperature. It features low toxicity, high density, and unique volume expansion during solidification from molten state. We supply multiple forms including bismuth ingot, granule, shot and powder with purity grades from 99% to 99.999% (2N~5N).
