Tungsten is one of those metals, which rely heavily on the recycling of tungsten scrap (W Scrap) and tungsten alloy scraps (W Alloy Scrap). When we talk about a high temperature scrap metal or a high temperature alloy scrap, tungsten and tungsten alloy scraps top the list. With a melting temperature of 3422 0C, tungsten and tungsten alloy scraps are only second to carbon.
