Exotic Spinodal Alloys for Superior Strength Spinodal alloys are highly specialized and possess excellent corrosion resistance. They benefit from age hardening techniques that further increase their strength and hardness while offering superior mechanical and physical properties in comparison to conventional high-performance alloys. These exceptional properties are advantageous for demanding oil and gas and drilling applications where performance is critical. Spinodal alloys offer a non-sparking and non- magnetic alternative to Beryllium containing materials with similar mechanical and electrical properties.
Examples of high performance spinodal alloys include, Pfinodal® (C72900) copper alloy and AM-388™ (UNS C72650). These grades are manufactured using sophisticated wrought powder metallurgy and are engineered into multiple product forms of strip, wire, and machined components.
Hardenable Spinodal Strip via Wrought Powder Metallurgy Pfinodal® strip can be age hardened with a heat treatment to ensure the high hardness required for deep hole penetration applications. The heat treatment produces superior mechanical properties up to 195 ksi ultimate tensile strength (1344 MPa) and 410 Hardness (VHN). Critical applications include electronic connectors and parabolic cone shaped charges for the perforation of oil and gas well liners.
AM-388™ strip can be also be age hardened up to 155 ksi ultimate tensile strength (1068 MPa) and 380 Hardness (VHN). Alloys that are age hardenable, non-magnetic and non-conductive are best suited for the oil and gas industry.
Hardenable Spinodal Strip via Wrought Powder Metallurgy
Applications include strip for non- sparking tools and electronic connectors.
Both of these hardenable strip products can be roll-tempered to meet highly precise mechanical properties.
High Hardness Pfinodal® Shaped Components for Demanding Drill Bit Applications Pfinodal® shaped components offer specific physical properties that are highly advantageous for tri-cone drill bits in demanding rock bit bearing applications, including excellent corrosion resistance.
The production processes and heat treatments employed in creating this type of metal components combine to ensure the high hardness and non- magnetic properties required in bearing material for bearing sleeves, bushings, washers and caps. The low distortion of Pfinodal® during hardening allows for the complex forming of parts and shapes prior to heat treatment without the need for costly fixtures.
Pfinodal® Shaped Components for Drill Bit Applications
Corrosion Resistant Clad Plate Roll bonded clad plate is a multi- layer plate composed of two or more different materials called base metal (usually carbon steel or low alloy steel) and a higher alloy cladding metal, such as stainless steel, nickel alloys, or titanium. The clad plate combines higher strength and better thermal conductivity of lower cost base material with the corrosion resistance of higher cost cladding material.
This high-quality composite plate is engineered to meet critical standards in pressure vessels, autoclaves, and similar applications where corrosion, pressure resistance, and structural performance are key. Other applications include chemical processing chambers, transition joints, refining, flue gas desulfurization, and catalytic cracking.
Quality, Safety and Longevity First Put simply, the greater the choice of materials that can provide the very best corrosion and pressure resistance to extend and enhance critical working lifespans, the better choice the customer will have when it comes to selecting the right metals and materials. In the long-term, ‘fit and forget’ products in higher corrosion- resistant alloys are key to reducing downtime and maintenance costs in extreme oil and gas environments.
Customers around the world are turning more and more to Pfinodal® shaped components to significantly extend their drill bit life and reduce downtime when it comes to maintaining and keeping the drills in optimum working condition.
