UTP A 6225 Al is suitable for welding of identical and similar alloys, such as NiCr25FeAlY, Material-No. 2.4633. These alloys are applicable for working temperatures up to 1200° C, particularly for thermal treatment ovens.

High oxidation resistance at high temperatures (also in cyclic conditions) , very good corrosion resistance in carburised medias, excellent high temperature resistance.
