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.
High entropy alloys
High entropy alloys
High entropy alloys are the materials that have been recently mastered by POLEMA.
These materials own unique corrosion resistance and they are capable of maintaining strength and flexibility even at ultra-low temperatures, and a stable phase composition during thermomechanical processing.
Suitable for the production or improvement of product properties by such methods as weld deposition or 3D printing.
