Inconel Casting

Why Choose Casting for Inconel?

Inconel alloys are among the most expensive raw materials in manufacturing. Inconel Investment Casting (Lost-Wax Casting) offers a strategic advantage by producing components as “Near-Net Shapes,” significantly reducing the “Buy-to-Fly” ratio and minimizing expensive CNC machining time.

The AlloyAccu Advantage

  • Vacuum investment casting of nickel-based superalloys.
  • Fine grain structure ensuring excellent mechanical properties.

Our Inconel Casting Capabilities

From intricate small parts to structural housings

Precision Investment Casting

Best for: Intricate geometries, thin walls, and superior surface finishes.

Grades: Inconel 718, 625, 713C

Tolerances: ±0.127 mm per 25mm

Finish: Ra 1.6 – 3.2 μm

Complex Internal Geometries

Best for: Hollow turbine blades, manifolds, and heat exchanger components.

Specialty: Use of soluble ceramic cores to create intricate internal passages that are impossible to achieve via traditional machining.

Post-Casting Operations

  • HIP: Hot Isostatic Pressing for 100% density.
  • CNC Finish: In-house 5-axis to ±0.005mm.
  • Heat Treat: Solution & Age for strength.

Technical Specifications: Casting vs. Machining

Feature Investment Casting (Near-Net) CNC Machining (From Solid)
Design Complexity High (Internal channels allowed) Limited by tool access
Material Usage High Efficiency (Minimal waste) High Waste (Large chip volume)
Initial Tooling Cost Moderate to High (Mold required) Low (No mold needed)
Production Volume Ideal for Mid to High Volume Ideal for Prototypes & Small Batches
Lead Time 6–10 weeks (Includes tooling) 2–4 weeks

Need prototypes fast? We support 3D-printed wax patterns to bypass tooling lead times for R&D.

Industry-Leading Quality Control (NDT)

Because Inconel castings often serve in failure-critical environments, we provide comprehensive validation to ensure every part meets the strictest standards.

X-Ray Inspection (Radiography)

To detect internal inclusions, porosity, or shrinkage defects.

FPI (Fluorescent Penetrant Inspection)

To identify any surface-breaking defects undetectable by eye.

Spectrographic Analysis

Verification that every heat of metal meets specific UNS chemical requirements.

Full Traceability Package

  • Material Test Reports (MTR)
  • Dimensional Inspection Reports
  • Heat Treatment Charts
  • NDT Certifications

FAQ: Inconel Casting Expert Q&A

Q: What is the typical lead time for a new Inconel casting project?

A: New projects typically require 4-6 weeks for tooling/mold creation, followed by 2-4 weeks for the first article inspection (FAI) samples.

Q: Does casting Inconel affect its corrosion resistance?

A: When cast under vacuum and properly heat-treated, Inconel 625 and 718 maintain the same excellent corrosion and oxidation resistance as their wrought counterparts.

Q: Can you cast small quantities for R&D?

A: Yes. While investment casting is geared for production, we support R&D through 3D-printed wax patterns, which eliminates the need for expensive hard tooling for prototypes.
