Cobalt (Co) is a lustrous, silvery-blue, non-ferrous metal found in smaltite, cobaltite, and erythrite minerals. Cobalt alloys are metal alloys containing cobalt as the base material. They have excellent high strength and toughness, high temperature strength and resistance, and good corrosion resistance. Cobalt alloys made be categorized based on their key material advantages. These include […]
More than 350 years ago, porcelain makers in China incorporated a unique peach colour into their designs by means of a tungsten pigment that was not known in the West. Indeed it was not for another century that chemists in Europe became aware of it. In 1779, Peter Woulfe examined a mineral from Sweden and […]
Only tungsten and carbon have higher melting points. Rhenium has good wear resistance and it can withstand arc corrosion. It is soluble in nitric and sulphuric acids. Applications for the metal include its use as an alloying element with tungsten. The rhenium powder is a light-gray metal powder made of agglomerated single crystals. Rhenium has […]
In actual fact, niobium, like all other metals, is gray. However, by applying a passifying oxide layer, we allow our metal to gleam in a beautiful array of colors. Niobium is ductile and occurs with tantalum in a natural ore. Like tantalum, niobium also features outstanding chemical and oxidation resistance. Niobium has a gleaming white […]
