Symbol (1)Name (5)

(1) black = solid, red = gas, blue = liquid, grey = synthetically prepared(2) Based upon carbon -12. Values in brackets indicate most stable or best known isotope.(3) Entries marked with asterisks refer to the gaseous state at 273 K and 1 atm and are given in units of g/l.(4) blue = not radioactive, orange = radioactive(5) Names and symbols marked with asterisks are those recommended by IUPAC as systematic alternatives to those suggested by the purported discoverers. Berkley (USA) researchers have proposed Rutherfordium (Rf) for element 104, Hahnium (Ha) for element 105 and Seaborgium (Sg) for element 106. Dubna (USSR) researchers, who also claim the discovery of these elements have proposed different names (and symbols).

Strong metals.Whether it's high temperatures, aggressive chemicals or extreme mechanical loading: when conventional materials come up against their limits, molybdenum,

tungsten, tantalum, niobium and chromium take over. For more than 90 years, we have been working with these refractory metals. We know exactly what they

are capable of and can manufacture even the most complex products out of them. To make sure that the properties of our materials precisely meet your

requirements, we enrich them with additional metallic and ceramic materials to form alloys and composites.

We manufacture and market our high performance metals worldwide. Production sites in Europe, USA and Asia and a global network of sales

subsidiaries and sales partners, enable excellent customer service and outstanding product quality.
