Molybdenum and tungsten products for production of leucosapphires
POLEMA JSC is the leading global manufacturer of chromium, molybdenum, tungsten products, metal powders and composite materials.
Sputtering Ni, NiCr targets and evaporable Ni, NiCr cathodes
Field of use
Mechanical engineering, electronics. Protective coatings on machine and equipment parts.
Shape
- Simple-shape products, with rectangular or round cuts, in the form of sheets, plates, rods and discs.
- Complex-shape products (cathodes) cut according to the client's drawings.
The shape, dimensions, permissible deviations for product size and the tooling precision are determined by the client's request.
Chemical composition
Products of the grade N1-PM (Ni-PM) are produced at the client's request, products of the grades NP1, NP2 can be produced according to State Standard 492-2006.
Guaranteed purity of the material is at least 99.9 % of Ni with minimal content of harmful impurities.
The chemical composition of products is ensured to be no lower than the requirements for nickel powders of the group U under State Standard 9722-97.
