In industries where extreme temperatures and corrosive environments are the norm, standard steels often fall short. ICAST ALLOYS LLP specializes in the precision investment casting of Nickel-Based Alloys, providing "near-net-shape" components that deliver unrivaled durability and performance.
By utilizing the "lost wax" process, we produce intricate, high-precision parts that minimize the need for secondary machining, saving you both time and material costs.
Nickel alloy castings are the "unsung heroes" of modern engineering. Because they maintain mechanical stability where other metals fail, they are essential for:
Oil & Gas: Isolation and flow control valves, downhole tools, and pump impellers exposed to sour gas and seawater.
Chemical Processing: Reactor components, heat exchangers, and piping systems handling aggressive acids (sulfuric, hydrochloric).
Aerospace & Defense: Turbine blades, jet engine exhaust systems, and structural components that operate at temperatures exceeding $1000^\circ\text{C}$
Marine Engineering: Seawater valves, propeller shafts, and desalination plant equipment resistant to chloride-ion stress corrosion.
Power Generation: Industrial gas turbines and high-pressure steam valves.
Inconel: 600, 625, 718
Hastelloy: C-276, C-22, CW-2M
Monel: 400, K-500
Nickel Alloys: Nickel 200/201
Super Alloys: Rene 41, Haynes 230
Inconel: High-temperature strength and oxidation resistance up to $980^\circ\text{C}$
Hastelloy: Outstanding resistance to strong acids, pitting, and crevice corrosion
Monel: Excellent corrosion resistance in marine environments and hydrofluoric acid
Nickel Alloys: Highly conductive; ideal for electronic and chemical alkaline environments
Super Alloys: Engineered for extreme creep resistance and surface stability
Extreme Resistance: Superior resistance to oxidation, carburization, and corrosion in both oxidizing and reducing environments
Thermal Stability: Maintains high tensile and yield strength at cryogenic temperatures and extreme heat
Complex Geometries: Investment casting allows for thin walls and intricate internal cooling channels (like those in turbine blades) that are impossible to machine.
Surface Finish: Delivers a smooth as-cast finish (typically 3.2–6.3 µm Ra), reducing the need for expensive polishing or grinding
Near-Net Shape: Significant reduction in material waste compared to machining from solid bar stock
Higher Raw Material Cost: Nickel is a premium metal, making the initial investment higher than stainless steel
Processing Complexity: These alloys have high melting points and are reactive, often requiring specialized heat treatment or vacuum induction melting to prevent impurities
Work Hardening: While we offer in-house machining, nickel alloys are notoriously difficult to cut because they harden rapidly during the process
As a vertically integrated manufacturer, ICAST ALLOYS LLP maintains total control over the casting lifecycle. Our facility features:
Advanced Heat Treatment: All-electric furnaces with automated quenching for precise metallurgical properties.
Zero-Rejection Track Record: A commitment to quality that has seen zero rejections for critical parts over the last seven years.
Global Compliance: We provide material certifications and third-party inspections (Lloyds, BV, DNV, SGS) to meet international standards
