Our 1lb Bismuth Chunk is sourced directly from the Chenzhou Bismuth Group where it is produced and is 100% “virgin” metal (not recycled). We sell this metal by the 1lb pound increment, so if you need 10lbs, simply add a quantity of 10 to your cart. Be sure to see our bulk discounts for certain quantity levels if you would like to save money per pound. If you are interested in making a very large order, please contact us directly for pricing and availability. All metal shipments come with a certificate of analysis. * Atomic Number = 83 | Melting Point (F) = 524 | Atomic Mass= 208.98 | Boiling Point (F) = 2642 | Density (g/cm3) = 9.80 |
