Our Cobalt Rounds are all sourced directly from the Vale Mining Group in Canada where they are produced and are 100% “virgin” metal (not recycled). We sell this metal by the pound, 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. Each Cobalt Round varies in diameter, but on average they are about 1'' inch in diameter. * Please Note: Due to the irregular shape of this metal, the weight of your shipped order is approximate. All metal shipments come with a certificate of analysis.*
