Superalloys & Exotic Metals Casting & Machining

Superalloys & Exotic Metals: Inconel, Hastelloy & Cobalt-Chrome

ForceBeyond specializes in precision vacuum investment casting (VIM), heavy closed-die forging, and multi-axis CNC machining of high-temperature nickel, cobalt, and iron-based Superalloys and Exotic Metals. Engineered to maintain high mechanical strength, oxidation resistance, and structural integrity under severe thermal stress exceeding 1,200°F (650°C), superalloys are the foundation of modern aerospace, power generation, and advanced defense systems.

Utilizing state-of-the-art Vacuum Induction Melting (VIM) foundries and 15,000+ psi Hot Isostatic Pressing (HIP) vessels, ForceBeyond produces dense, defect-free superalloy hardware with full AS9100 Rev D quality compliance.

550–850 MPa (80–123 ksi) Extreme wear resistance, high polishability, and outstanding biocompatibility. Ideal for orthopedic knee/hip implants and heavy-wear valve trim.

Advanced Processing for Hard-to-Machine Alloys

Superalloys work-harden rapidly and generate extreme heat during machining, damaging conventional cutting tools. ForceBeyond overcomes these challenges through disciplined manufacturing strategies:

  • Vacuum Induction Melting (VIM): Casting inside high-vacuum chambers eliminates dissolved atmospheric gases and oxide inclusions, yielding high-purity grain structures.
  • Hot Isostatic Pressing (HIP): Subjecting superalloy investment castings to simultaneous high temperatures and extreme gas pressure eliminates internal microporosity, increasing rotational fatigue life by up to 300%.
  • High-Rigidity 5-Axis CNC Machining: Utilizing specialized ceramic and carbide tooling geometries, high-pressure through-spindle coolant (1,000+ psi), and rigid machine beds to cut complex 3D profiles without inducing thermal distortion.

Frequently Asked Questions

Why is Vacuum Induction Melting (VIM) necessary for superalloys?

Casting inside high-vacuum chambers eliminates dissolved atmospheric gases and oxide inclusions, yielding exceptionally high-purity grain structures required for extreme temperature environments.

How does Hot Isostatic Pressing (HIP) improve superalloy casting quality?

Subjecting superalloy investment castings to simultaneous high temperatures and extreme gas pressure (15,000+ psi) eliminates internal microporosity, increasing rotational fatigue life by up to 300%.
