Drill Bit Material

AMETEK Specialty Metal Products has led the industry in the production of Pfinodal® (C72900), a highly specialized Spinodal alloy, with superior bearing properties. Our production processes and heat treatments combine to ensure the high hardness required in tough drill bit material for bearing components such as sleeves, bushings, washers and caps. Our Pfinodal® (C72900) bearing materials has been in use for 20 years under patent numbers 5527113 and 5552106 for these rock bit bearing applications.

Advantages

The near-net shape processing of our Spinodal materials eliminates waste thereby reducing cost for the finished product. We specialize in offering the turnkey solutions of materials that are machined, plated and packaged to your specifications. These can be shipped to your facilities around the world for incorporation in the bits, reamers and equipment needed to power the world. Additional benefits of C72900 material includes:

• High hardness and strength
• Non-magnetic properties required in bearing material
• Non-sparking and non-corrosive
• Extended drill bit life in demanding drill bit bearing applications
• Safe Alternative to Beryllium Copper alloy (BeCu)

Safe Alternative to Beryllium Copper (BeCu)

Our Pfinodal® c72900 copper alloy material offers a non-sparking and non-magnetic alternative to Beryllium Copper (BeCu) with similar mechanical and electrical properties but without the harmful exposure risks. Spinodal alloys continue to replace Beryllium Copper alloys from the workplace thereby eliminating serious health risks and delivering a better product.

Extended Drill Bit Life

Widely considered as the best drill bit material, Pfinodal® c72900 copper alloy continues to be adopted by customers around the world to significantly extend drill bit life and reduce downtime when it comes to maintaining and keeping the drill bit components in optimum working condition.
