  • The mechanical properties of the metal are strongly dependent on its purity, structure, and crystal defects, as is the case with almost all refractory metals.
  • Even low concentrations of interstitial impurities increase the hardness and reduce the ductility.
  • The yield strength is strongly temperature dependent, the value at 200°C being ca. 30% of that at 20°C.

What is Tantalum?

Tantalum is a chemical element with symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, a hero from Greek mythology. Tantalum (Ta) is a dark blue-gray metal that is very heavy, ductile, and hard and has high corrosion resistance. Tantalum is especially resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluoric acid. It has the fourth-highest melting point of all metals and is able to form extremely thin and protective oxide layers for high-quality capacitors, making it an excellent material for tubes. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum. Tantalum is also used for medical implants and bone repair. Its main use today is in tantalum capacitors in electronic equipment such as mobile phones, DVD players, video game systems and computers. Tantalum, always together with the chemically similar niobium, occurs in the minerals tantalite, columbite and coltan (a mix of columbite and tantalite). Tantalum is a rare metal, comprising just 8×10−9% of the universe, making it fifteen times less abundant in the universe than gold (which makes up 6×10−8%). Tantalum also comprises just 1.5×10−4% of the earth’s crust, making it more abundant than other metals in the sixth period, such as rhenium (abundance 2.6×10−7%), osmium (abundance 1.8×10−7%), or iridium (abundance 4×10−8%), but not as abundant as barium (abundance 3.4×10−2%).

Prices for Tantalum Nuts, Bolts & Fasteners

Prices for Tantalum Nuts, Bolts & Fasteners are directly co related to prices of the raw materials such as iron ore, metal scrap, chromium, nickel and various other alloying elements. The production cost of heat resistant stainless steel and nickel alloy plates is high as they contain high amount of nickel and chromium. Meanwhile, mild steel material is among the lowest cost steel available, followed by carbon steel, 400 series stainless steels, aluminium, alloy steel, and 300 series stainless steel. Special alloys such as Titanium, Inconel, Monel and Hastelloy cost very high as the nickel, chromium and moly content is very high.
