Help of rare metals in rolling

Are you interested in a reference on rare metals? We offer to buy rare earth metals from specialized warehouses of the supplier Evek GmbH with delivery to any city. Full compliance with modern quality standards. Supplier Evek GmbH offers to buy any rare-earth metal, the price - optimal in this segment of rolled metal.

Rolling rare metals

Of the total number of rare and rare-earth elements, molybdenum and tungsten have the necessary plastic properties for rolling. Molybdenum products include powders, plates, sheets, wire, etc. They are used to produce flat and volumetric parts of laboratory and heating equipment, as well as consumables for electrical discharge machines.

Molybdenum sheet range

  • M-PM grade sheets, RF 17431-72 standard;
  • High-precision molybdenum sheets, Spec. 14-22-149-2001.

Rolled sheets are produced with thickness of 0.3...45 mm. It is characterized by high purity with respect to impurities and metal, as well as high plasticity and homogeneity of structure. Molybdenum sheets are supplied annealed to relieve internal stresses.

M-PM molybdenum sheets (temperature 20°C)

Thickness, mm Tensile strength, MPa Elongation, % Relative elongation Brinell hardness, NV
1,0...1,3 780...850 13...16 217...240
1,9...2,5 790...880 18...21 229...240
3,0...3,5 750...820 18...25 210...229

It is recommended to treat molybdenum sheets by local gas-plasma or inductive heating at temperatures depending on the rolling thickness and the degree of deformation during bending forming of the screen. For example, the recommended temperature range for a 0.5 mm thick sheet is> 100-3000°C, a 1 mm thick sheet → 150-3500°C, and a 2 mm thick sheet → 270-4700°C.

Molybdenum rods, electrodes.

Chemical composition. Modern methods of powder metallurgy ensure high purity of molybdenum with respect to metallic and interstitial impurities (C, N, O, H), the correct microstructure for heat-resistant structural materials used in electrical engineering and other installations operating under high pressure. Products have perfect ductility due to low metal and impurity content, fine grain structure. The bars are produced heat-treated, annealed to restore internal stress, unless otherwise specified by the customer.

Rolled sheets

Finely ground molybdenum ML-PM lanthanum oxide hardened ODS-Mo sheets and bars are also produced. The lanthanum oxide serves as a barrier to dislocation displacement during the deformation process. It stabilizes the structure of the alloy and provides strength and creep resistance at high temperatures. The material has high ductility in the recrystallized state, high strength at 1600 °C, and high resistance to deformation (creep) in the long-term strength test at 1800 °C. The material has good welding properties. Evek GmbH offers to buy rolled rare metal products. The supplier guarantees prompt delivery of products to any location specified by the customer

Rolling of tungsten and tungsten-molybdenum alloys

The most common plastic deformation of MW30-PM molybdenum-tungsten alloy is used to make crucibles and furnace supports. The hardened MW30 alloy has a high recrystallization temperature, strength and creep resistance at high temperatures.

Tungsten is characterized by maximum interatomic bonds, the highest melting point among refractory metals at 3420°, high density of 19.3 g/cm3, high strength, thermal conductivity, hardness (HV30> 460), creep resistance and long term durability. Refined tungsten has a higher recrystallization temperature of 1350°C compared to molybdenum, lower vapor pressure and evaporation rate at temperatures of 1800-2500°C, lower coefficient of thermal expansion and low electrical resistance. Tungsten sheet products are produced with a thickness of 0.5...45 mm.
