At ICAST ALLOYS LLP, we specialize in the precision manufacturing of Cobalt-based alloy investment castings. Known for their extreme durability, these "Super Alloys" are engineered for the most demanding industrial environments where standard steels fail. Our advanced lost-wax casting process allows us to produce complex, near-net-shape components that exhibit unparalleled resistance to wear, heat, and corrosion.
Cobalt alloys are the gold standard for mission-critical applications. Because of their ability to maintain mechanical properties at temperatures up to 1500°F (815°C), they are used across diverse sectors
Medical: Orthopedic implants (hip and knee joints), dental prosthetics, and surgical tools due to excellent biocompatibility.
Aerospace & Defense: Turbine blades, vanes, fuel nozzles, and engine components subject to high thermal fatigue
Power Generation: Gas turbine parts and nuclear reactor components
Industrial & Food Processing: Pump sleeves, rotary rings, valve seats, and plow tiles that face heavy abrasion or chemical exposure
Cobalt 6:Stellite 6
Cobalt 21:ASTM F75 / Stellite 21
Cobalt 31:Stellite 31
Cobalt 3:Stellite 3
Cobalt 25:L-605
Cobalt 6:Most widely used; excellent general-purpose wear and corrosion resistance.
Cobalt 21:Exceptional resistance to thermal and mechanical shock; standard for medical implants.
Cobalt 31:High tensile strength and creep resistance at elevated temperatures.
Cobalt 3:High carbon content for superior abrasion and erosion resistance.
Cobalt 25:Excellent strength and oxidation resistance up to 2000°F.
High-Temperature Strength: Unlike many metals, cobalt alloys retain their hardness even at "red heat" temperatures.
Exceptional Wear Resistance: Superior anti-galling properties make them ideal for metal-on-metal sliding applications.
Corrosion & Oxidation Resistance: Naturally forms a protective oxide film that prevents rust and chemical degradation.
Precision Geometry: Our investment casting process achieves tight tolerances (±.005 inches per inch) and a smooth surface finish (120 RMS or better), reducing the need for secondary machining.
Higher Material Cost: Due to the scarcity and performance of cobalt, raw material costs are higher than stainless or carbon steels.
Machining Difficulty: The same hardness that makes these alloys durable also makes them incredibly difficult to machine; they often require specialized grinding or EDM (Electrical Discharge Machining).
Complex Processing: The high melting point of cobalt requires specialized ceramic molds and precise temperature control during pouring
As an ISO-certified facility, ICAST ALLOYS LLP combines technical expertise with rigorous quality control. We offer:
Near-Net Shape Casting: Minimizing waste and expensive secondary operations.
Non-Destructive Testing (NDT): Ensuring internal integrity through X-ray, Dye Penetrant, and Magnetic Particle inspection
Custom Tooling: In-house capability to develop complex patterns for intricate designs
