Wide Ranging Nickel Based Alloys
The Deloro alloys are nickel-based alloys with additions of typically Cr, C, B, Fe and Si. They cover a very wide range of hardness from soft to tough, and can be easily machined or hand-finished to exceptionally hard, wear-resistant alloys. Deloro alloys can be selected based on hardnesses between 20 and 62 HRC depending on the application.
The lower hardness Deloro alloys are typically used for glass-forming molds. The higher hardness Deloro alloys are used in severe wear applications, such as rebuilding the flights of feeder screws, and they can be blended with carbides for an even harder deposit. They maintain their properties up to temperatures of about 315° C (600° F) and also offer good oxidation resistance.
