Cobalt has the look and feel of white gold and is a bright, white metal that is even brighter than titanium and tungsten. It is sometimes referred to as ‘cobalt chrome’ and compared to platinum and palladium in colour. Why is cobalt so valuable? Current battery technologies require cobalt as Read more…
But keep in mind that they are not scratch proof. Unlike tungsten bands, rings made solely with cobalt can scratch – although not easily. If scratches do occur, they can be buffed out with a professional buff treatment. Do cobalt rings tarnish? Similar to platinum in color, cobalt does not Read more…
The only way is to contact the retailer which sold you the ring and ask them if the ring contains cobalt. Ideally, the ring should be labeled with what it has been alloyed with – and many cobalt free tungsten rings are labeled as ‘cobalt free. Does tungsten contain cobalt? Read more…
Cobalt rings are so much harder than steel that normal steel cutting blades will not cut through a cobalt ring. In order to cut through a cobalt ring, you will need to purchase a diamond impregnated cutter, the pack we show in the video was purchased for about £5 from Read more…
IDTechEx forecasts that a combined total of over 180,000 metric tons of lithium, cobalt, nickel and manganese could be recovered by 2030 through battery recycling, a value that is forecast to grow by approximately tenfold by 2042. Can lithium and cobalt be recycled? Only once the pack has been dismantled, Read more…
silvery metal. Cobalt is a lustrous very hard silvery metal belonging to a group called the “transition metals”. It is one of only 3 ferromagnetic transition elements along with iron and nickel.
