Vacuum Casting for Nickel & Cobalt Alloys
Why pouring under ≤10−5 mbar delivers superior properties for aerospace and other critical applications.
Vacuum Casting: Precision Engineering for Nickel & Cobalt Alloys
Superior Strength. Purity. Reliability.
At Investment & Precision Castings Ltd. (IPCL), our advanced vacuum investment casting process achieves what conventional methods cannot — ultra-clean, high-strength components in Nickel- and Cobalt-base alloys, designed for aerospace, defense, and high-temperature energy applications.
By pouring molten metal under high vacuum conditions (=10?5 mbar), oxidation and gas porosity are virtually eliminated — ensuring flawless metallurgical integrity and exceptional surface finish (Ra 1.6–3.2 µm).
Why Vacuum Casting Outperforms Conventional Casting
In conventional air or inert-gas casting, trace gases and oxides reduce strength, fatigue life, and corrosion resistance. IPCL’s vacuum melting and pouring technology solves this by creating a contamination-free environment for critical alloys like Inconel, Hastelloy, Stellite, and other superalloys.
- Superior microstructure integrity — no oxide films or gas inclusions
- Higher fatigue and creep strength for turbine and rotating components
- Improved alloy purity for reliable long-term performance
- Better repeatability and reduced rework
- Smooth surface finish (Ra 1.6–3.2 µm) vs. 4.5–6.4 µm in regular casting
