Tantalum is extremely corrosion resistant due to the formation of an oxide film, and is also resistant to acid attack (with the exception of HF). It will react with fused alkalis and a variety of non-metals at elevated temperatures.
Niobium has an abundance of 20 ppm in the earth's crust. As a pure metal, it is very reactive and forms an extremely stable oxide when exposed to air which enhances its corrosion resistance. Niobium will react with a variety of non-metals at elevated temperatures.
Molybdenum has great strength at high temperature, low vapor pressure and low thermal expansion as well as excellent conductivities. It is used in aircraft parts, electronic applications, glass manufacturing, filaments, and many other applications. Due to its excellent thermal conductivity and low electrical resistivity, molybdenum is also widely used in the furnace industry for radiation screens, elements, and sintering trays.
Titanium and Titanium alloys can be used in aerospace, military, medical, jewelry, telecommunications and other industries. There are several grades of Titanium. Grade 1 to Grade 4 are of pure Titanium, and the other grades are of alloys. Pure Titanium is used for its high corrosion resistance, and its alloys, for their extremely high strength to weight ratio.
Stanford Advanced Materials supplies pure Tungsten products such as Tungsten metal powder, Tungsten metal and Tungsten wire, etc., high density Tungsten alloy products such as Ferro Tungsten. We can manufacture customized products of different shapes and specifications according to clients’ requirements.
Zirconium, with atomic symbol Zr, has a content of about 130ppm within the Earth's crust. It is not found in nature as a pure metal. Because of Zr's excellent resistance to chemical corrosion, it is often used as a composition for alloys that are required to be exposed to aggressive environments. The major commercial source of zirconium is the silicate mineral and zircon (ZrSiO4).Zirconium Product
Rhenium is one of the rarest elements in the Earth's crust and the last stable element discovered. The free element has the third-highest melting point and highest boiling point of any element. The largest user for Rhenium is jet engine and the chemical industry's catalytic uses being next-most important.
Indium's current primary application is to form transparent electrodes from indium tin oxide (ITO) in liquid crystal displays and touchscreens, and this use largely determines its global mining production. It is widely used in thin-films to form lubricated layers (during World War II it was widely used to coat bearings in high-performance aircraft). It is also used for making particularly low melting point alloys, and is a component in some lead-free solders.
Iridium is a platinum group metal with atomic number 77. Ir is very hard and brittle metal with silvery color. Iridium has great corrosion resistant even at high temperature as 2000C. Iridium is an ideal material for tip of spark plugs and has been used to make crucible for artificial crystals manufacturing.
