Molybdenum scraps (Mo Scrap) are very unique with their position as a high temperature scrap metal. Molybdenum scrap have a melting point of 4,730 F. This puts molybdenum scrap melting at 2,000 F higher than other scrap metals such as steel. Molybdenum scraps are used for many things in the world today

Molybdenum Metal Molybdenum metal is used in: • Alloying agent – contributing hardenability, toughness to quenched/tempered steels. It also improves the strength of steels at high temperatures (red-hardness). • In nickel-based alloys (such as Hastelloys®) and stainless steels it imparts heat-resistance and corrosion-resistance to chemical solutions. • Electrodes for electrically heated glass furnaces and forehearths. • Nuclear energy applications, as missile and aircraft parts (where high temperature resistance is vital). • As a catalyst in the refining of petroleum. • As a filament material in electronic/electrical applications. • As a support members in radio and light bulbs. • Arc resistant electric contacts. • Thermocouple sheaths • Flame- and corrosion-resistant coatings for other metals (generally arc deposited for metallising).

Originally molybdenum was confused with graphite and lead ore, and was not prepared till 1782 by Hjelm in the impure state. Molybdenum does not occur native, and is obtained mainly from molybdenite (MoS2). Other minor commercial ores of molybdenum are powellite (Ca(MoW)O4) and wulfenite (PbMoO4). It may also be recovered from copper and tungsten operations as a by-product. The metal is prepared from the powder made by the hydrogen reduction of purified molybdic trioxide or ammonium molybdate. Molybdenum the metal is silvery-white, and very hard. However, it is softer and more ductile than tungsten and is readily worked or drawn into very fine wire. It cannot be hardened by heat treatment, only by working. It exhibits a high elastic modulus and a very high melting point. Above temperatures of 760°C (1400°F) molybdenum the metal forms an oxide that evaporates as it is formed and its resistance to corrosion is high. It has a low thermal expansion and its heat conductivity is twice that of iron. It is one of the few metals that has some resistance to hydrofluoric acid. Key Properties Molybdenum is a refractory metal typically used in high temperature applications. Key properties include: • Low co-efficient of thermal expansion (5.1x10-6 m/m/°C) which is about half that of most steels • Good thermal conductivity • Good electrical conductivity • Good stiffness, greater then that of steel (Young’s Modulus 317MPa) • High melting point (2615°C) • Good hot strength • Good strength and ductility at room temperature • High density (10.2 g/cm3)

In fact, it can work at temperatures above 1100°C (in non-oxidising conditions), which is higher than steels and nickel-based superalloys Available all over India
