Aluminum Centrifugal Castings for High-Precision Industrial Applications
At Johnson Centrifugal Technology (JCT), we specialize in aluminum centrifugal castings engineered to deliver forged-equivalent properties, superior cleanliness, and consistent mechanical performance. Our aluminum centrifugal casting process combines centrifugal force with deep metallurgical expertise to produce aluminum components with exceptional integrity and repeatability.
JCT aluminum centrifugal castings are trusted in demanding applications across the Semiconductor, Medical, and Gas & Steam Turbine industries, where precision, material purity, and performance are critical.
Aluminum Alloys for Centrifugal Casting
JCT produces aluminum centrifugal castings in a range of high-performance alloys selected for strength, machinability, corrosion resistance, and structural consistency. Our alloy expertise allows us to tailor chemistry and temper to meet exact application requirements.
6061 Aluminum Centrifugal Castings
Our proprietary JC6061™ aluminum centrifugal castings (forged-equivalent 6061) are significantly cleaner than traditional aluminum castings, with zero inclusions and a uniform equiaxed grain structure. This allows mechanical testing in any axis with consistent results and makes 6061 aluminum centrifugal castings ideal for precision machining and vacuum-critical environments.
The JC6061™ – T6C AnoMaxx® aluminum centrifugal casting alloy meets the most demanding semiconductor requirements, offering:
- Super-clean chemistry exceeding industry standards
- Outstanding anodizing response
- Excellent strength and superior machinability
- Optional refinement of chemical limits

356 Aluminum Centrifugal Castings
356 aluminum centrifugal castings, including T6 and T5 conditions, offer excellent castability, dense grain structure, strong mechanical properties, and superior machinability. These aluminum centrifugal castings are commonly used for seal rings and precision components in power generation, paper-making processes, marine, military, and industrial equipment.

7075 Aluminum Centrifugal Castings
7075 aluminum centrifugal castings provide an exceptional strength-to-weight ratio for high-stress applications. JCT’s centrifugal casting process produces dense, defect-free 7075 aluminum components suitable for structural, subsea, and load-bearing designs.
Industries & Applications for Aluminum Centrifugal Castings
Semiconductor Manufacturing
JCT aluminum centrifugal castings are widely used for vacuum-tight semiconductor components, including process chambers and shields, with no porosity or contamination. Our aluminum centrifugal cast components meet stringent pump-down and rate-of-rise standards, achieving operating vacuum pressures from 10⁻⁹ through 10⁻¹⁵.
