Strip and foil so as other semi-finished products - sheets and flat bars - belong to flat products. The described products have a much less width and thickness so this allows using them in small-sized products. Useful properties of molybdenum (refractoriness, hardness, high temperature resistance, corrosive resistance, plasticity (after heating) are retained.
Metotechnics company offers molybdenum foil and strip. The products can be ordered on the prices page or via e-mail and by phone.
Grades, production technologies, sizes, supply condition, applications of the described products are given in the corresponding sections of this page.
Grades
The products are made of pure molybdenum. Molybdenum is the main component, its content is 99.948 - 99.953%. Also such admixtures iron (Fe), aluminium (Al), nickel (Ni), silicon (Si), calcium (Ca), magnesium (Mg), carbon (C).
The chemical composition of MCh foil is regulated by TC 48-19-245-84 standard.
Production
Molybdenum strip and foil are produced of P-MCh plates baked in vacuum or reducing medium. Such plates are made of molybdenum powder. Rolling is the main technological operation for making these products. Firstly it is made simultaneously with heating the blanks (hot) and then without heating (cool). This is used for making molybdenum foil and strip 0.02- 0.09 mm thick.
Edge trimming belongs to additional technological operations performed for the semifinished products. Chemical and thermal processing are not applied, the products are unnannealed.
Molybdenum strip and foil have a similar form factor. They are flat, rather thin, narrow and long. These products are supplied in rolls.
Sizes, mechanical properties, supply condition and other technological peculiarities of semifinished products described in TC 48-19-245-84 standard.
Application
Molybdenum foil and strip are used for solving sector-specific scientific and industrial tasks. Usually this refractory metal is used in products that work under high temperatures and increased mechanical load. It is used for making heat-absorbing screens for finishing furnace combustion chambers and different components of electronic devices - anodes of oscillator tubes, heat-insulating and absorbing membranes of semi-conductors and other components.
