Cobalt  is a chemical element with symbol Co and atomic number 27. Cobalt is a hard, lustrous, silver-gray metal. Cobalt is used in the preparation of wear-resistant, high-strength alloys and cobalt is widely used in magnetic recording because it is only one of the three room temperature ferromagnets that has unaxial symmetry and therefore can be used in digital recording. Cobalt makes alloys easily with the other metals and temperature stability of these alloys make them suitable for use in turbine blades for gas turbines and jet aircraft engines. Cobalt based alloys are also  corrosion  and wear-resistant. Cobalt alloys are also used for dental prosthetics where they are useful to avoid allergies to nickel. When we look at the usage areas of  cobalt sputtering targets , it can be said that  cobalt sputtering targets  can be used in sputtering applications to produce thin films on microelectronic devices such as microprocessors, DRAM's, etc. DC magn...

Cobalt, iron and boron get together to form an alloy and this alloy can be used as a sputtering target. Let’s look at the applications that cobalt, iron and boron alloy can be used. Boron alloy with transition metals like cobalt iron boron have many attractive properties, including high melting point and hardness, good wear and corrosion resistance, excellent electrical conductivity, and resistance to attack by molten metals. There therefore appears to be significant scope for enhancing surface properties of metals and ceramics by applying coatings constituted from these materials. Also, there are many applications which require a high ultimate tensile strength, high thermal stability and ease of fabricability. All these properties can be obtained by using alloys. For example, metal ribbons used in razor blade applications usually undergo a heat treatment of about 370° C for about 30 min to bond an applied coating of polytetrafluoroethylene to the metal. Likewise, metal strands us...
