Types of Refractory Metals For Sale
Ferro Alloy
Ferroalloy, a master alloy composed of iron and one or several elements, mainly used in steel smelting. In the iron and steel industry, all master alloys used in steelmaking, whether iron-containing or not (such as silicon-calcium alloys), are also called 'ferroalloys', It is customary to also include some pure metal additives and oxide additives.
We Provide Refractory Metals For Various Industries
-01-
Semiconductors
Elemental semiconductors are semiconductor materials made from a single element. There are mainly silicon, germanium, selenium, etc., with silicon and germanium being the most widely used.
-02-
Medical Devices
Tantalum is a refractory metal with great biocompatibility, but tantalum has high density and poor mechanical properties. Its biomedical applications include:
1. Cast pure tantalum surgical implant: ASTM F560;
2. Pure tantalum coating:
3. Sutures for plastic surgery and neurosurgery;
4. Radioisotopes for the treatment of bladder tumors.

Civil Aerospace
Superalloys are not only key materials for hot end components such as fuel chambers, guides, turbine blades and turbine disks of aero-engines, and high-temperature components of aerospace rocket engines, but also high-temperature corrosion-resistant components required by industrial gas turbines, energy, and chemical industries. Superalloys are indispensable important materials in the national economy.

Defence
The melting point of tungsten is the highest among metals, and its outstanding advantage is that the high melting point brings good high temperature strength and corrosion resistance of the material, and it shows excellent characteristics in the military industry, especially in the manufacture of weapons.
-05-
Energy
Superalloys have a wide range of applications in the energy field. In high-parameter ultra-supercritical power generation boilers for coal power, superheaters and reheaters must be used with good creep resistance, oxidation resistance on the steam side and corrosion resistance on the flue gas side.
Superalloy pipes with excellent performance; in gas turbines, turbine blades and guide vanes need to use hot-corrosion-resistant superalloys with excellent high-temperature corrosion resistance and long-term structure stability; in the field of nuclear power, steam generator heat transfer tubes must be selected Superalloys with good solution corrosion resistance; in the fields of coal gasification and energy saving and emission reduction, superalloys with excellent high temperature thermal corrosion resistance and high temperature abrasion resistance are widely used; in oil and natural gas mining, especially in deep well mining, drilling tools In the acidic environment of 4-150 ℃, coupled with the existence of CO_2, H_2S and sediment, etc., corrosion-resistant and wear-resistant superalloys must be used.
-06-
Automotive
Another important application of high temperature materials in automotive engines is the turbocharger. The turbocharger uses the exhaust gas discharged from the cylinder to drive the turbine on a diesel engine or an internal combustion engine to increase the pressure of the intake air, thereby increasing the intake air volume and intensifying combustion.
-07-
Additive Manufacturing
The alloys used in iron and steel plants are the iron alloys required for deoxidizing and alloying the molten steel after tapping.
-08-
Electronics
Rare metals are: germanium, silicon, nickel, etc., mostly used in diodes (germanium, silicon), triode, SCR and temperature controller (nickel).
Benefits of Using Refractory Metal Products
Corrosion resistance
Refractory metals' most advantages are their strength at high temperatures and with well performance corrosion resistance to molten alkali metals and steam.
Low temperature brittleness
Brittleness occurring during plastic deformation of high melting point metals.High melting point metals such as tungsten, molybdenum, tantalum, niobium, zirconium and hafnium are high temperature materials for atomic energy, aerospace, electric light source, electric vacuum, military and other industrial applications
Oxidation resistance
The high temperature oxidation resistance of metal refers to the resistance of steel to oxidation at high temperature, and it is an important guarantee condition for whether steel can work at high temperature for a long time.
List of Refractory Metals
Tungsten
Tungsten has the richest content, the highest melting point and the highest metal density among types of refractory metals.
Molybdenum
Molybdenum is the most commonly used refractory metal, because it is cheaper than most other metals, and after being made into alloy, molybdenum products can resist creep and high temperature very well.
Tantalum
HSG tantalum products have the greatest corrosion-resistant performance among refractory metals.
Niobium
Niobium, often used with tantalum, is very special and can be easily processed to achieve high elasticity and strength.
Rhenium
Rhenium is the latest discovered refractory metal. It can be found in other refractory metal ores at super-low concentrations.
