Our Alloys

Geronimo Alloys can manufacture parts made of stainless alloys as well as the generic equivalent of various trademarked alloys. So if you are looking for a more cost-effective alternative to trademarked materials such as Incoloy® alloys or Nitronic® alloys for replacement parts, you have come to the right place. Whether the part you need is a cobalt-based, nickel-based, or high-nickel alloy, we will manufacture it according to its original base material.

Cobalt-Based Alloys

Geronimo Alloys custom-machines parts out of many cobalt-based alloys. These include Stellite® (a registered trademark of Kennametal Inc.) equivalent and other similar trademarked cobalt alloys.

Stellite® (a registered trademark of Kennametal Inc.) Equivalent Alloys

Stellite® is a registered trademark name.  We do not cast products using any trademarked named alloys, but do purchase trademarked alloys in bar stock for some applications.  In order provide the highest quality products, while maintaining the lowest possible cost for our customers, we do not PURCHASE or SELL any alloys produced by Kennametal, Inc. and do not use their trademark names.  The generic name for this family of alloys is cobalt-based alloys.  Many cobalt alloys carry UNS (Unified Numbering System) numbers. The following chart shows a few examples:
