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.
