Rare and refractory metals

You are interested in the characterization of rare and refractory metals? Supplier KMZ offers to buy at economical price and rare refractory metals. Supplier guaranteed timely delivery at any address specified by the consumer.

The group of refractory metals

The term «refractory metal» is used to describe a group of metal elements that have exceptionally high melting point and resistance to wear, corrosion and deformation. In industrial use is most often used with the following elements:

• Molybdenum (Mo)
• Niobium (Nb)
• Rhenium (Re)
• Tantalum (TA)
• Tungsten (W)

These five rare earth elements have a melting temperature above 2000 °C. its strength at high temperatures combined with toughness makes them ideal for alloying tool steel. Less frequently used:

• Chromium (Cr)
• Hafnium (Hf)
• Iridium (Ir)
• Osmium (Os)
• Rhodium (Rh)
• Ruthenium (Ru
• Titanium (Ti)
• Vanadium (V)
• Zirconium (Zr)

Technical characteristics

The most rare and refractory metals are very resistant to thermal shock, resulting in repeated heating and cooling will not easily cause thermal cracking. All considered metals have high density and good electrical and thermal conductivity properties. Other important properties are resistance to creep and to corrosion at high temperatures.

Processing and application

Because of the extreme refractoriness and hardness of rare and refractory materials most often used in powder form. Sintering of powder includes heating it inside the mold for a long time. When heated, the powder particles begin to contact, forming a solid item. Refractory alloys based on rare and refractory metals and their carbides are used in almost all industries including electronics, aerospace, automotive, chemicals, mining, nuclear technology, metal processing, etc.
