cobalt vanadium iron iron is an excellent choice for many applications that require high strength, ductility and magnetic properties. It maintains good tensile properties after heat treatment, making it ideal for high stress applications. It is also known for its excellent fatigue resistance, high magnetostriction and low core loss. It is readily available in the form of strip, plate and rods.

Cobalt-vanadium-iron-alloys such as Permendur 49 are widely used in magnetic and high-temperature applications because of their excellent magnetic and mechanical properties. The alloys contain 47.5 to 50.5 weight percent cobalt, 1.7 to 2.1% vanadium, a controlled carbon content of 0.025 to 0.1% and the balance essentially iron. The alloys have the advantage of increased yield strength and relative insensitivity to normal variations in annealing conditions. The tensile and fatigue strengths of the alloys are substantially higher than those of the prior art cobalt-cobalt alloys.

The rates of ordering and antiphase domain coalescence during isothermal annealing of quenched equiatomic cobalt and cobalt-cobalt-vanadium alloys have been studied by the use of X-ray diffraction (superlattice line intensity and breadth, lattice parameter and magnetic-saturation measurements). The results show that additions of vanadium up to 2.5% do not affect the transformation kinetics or the rate of ordering, but they do decrease the critical temperature for order by 11°C.

Iron is a very strong, relatively lightweight metal that is used to make springs, high-speed tools and surgical instruments. It is also found in gears, crankshafts and armor plating. Alloys of iron with cobalt, nickel and chromium are used in aircraft and jet engines. It is also combined with aluminum and titanium to make the alloys nichrome, invar, monel and terlitol, which do not expand when heated.

Pure iron is soft and corrodes easily, so it is usually mixed with other metals to improve its strength and durability. Cobalt is used to strengthen steel and to produce arc welding rods. It is also found in the alloys nichrome, invar and monel, which do not corrode in sea water. It is a necessary component of vitamin B12 (cyanocobalamin), which is essential for human health.

Nickel is a hard, silvery metal that is sometimes alloyed with iron to improve its corrosion resistance. It is also used in permanent magnets, notably the Alnico alloys of aluminum, nickel and cobalt which have very high magnetic saturation moments. Alloys of nickel with chromium, molybdenum and tungsten are used to make stainless steels which resist attack by rust. It is a critical ingredient in the enzyme nitrogenase, which is required for photosynthesis in plants and some bacteria.

Vanadium enhances the cold workability of iron-cobalt-vanadium (FeCoV) and improves its ductility at low temperatures. It also reduces the melting point of FeCoV, thereby increasing its ability to be machined.
