Deloro™ Alloys

Deloro™ alloys are nickel-based and are usually designed within the Ni-Cr-B-Si system. They cover a wide range of hardness from relatively soft, tough, build-up alloys that are easily machinable to exceptionally hard, wear-resistant alloys. They can be chosen within a hardness range of approximately 20 to 60 HRC depending on the application. The lower hardness Deloro™ alloys are, among others, typically used for glass forming molds. The higher hardness Deloro™ alloys are used in severe wear applications and they can even be blended with carbides for maximum hardness. They maintain their properties up to temperatures of about 700 °C and offer good oxidation resistance.
