Aluminum Castings for High-Precision Industrial Applications
At Johnson Centrifugal Technology (JCT), we specialize in high-performance aluminum castings engineered to deliver forged-equivalent properties, superior cleanliness, and consistent mechanical performance.
Using advanced centrifugal casting technology and deep metallurgical expertise, we produce aluminum components with exceptional integrity, repeatability, and dimensional precision.
Our aluminum castings are trusted in demanding applications across the semiconductor, medical, gas turbine, and steam turbine industries, where material purity, strength, and reliability are critical.
Aluminum Alloys for Industrial Castings
Johnson Centrifugal produces aluminum castings in a wide range of high-performance alloys, selected for strength, machinability, corrosion resistance, and structural consistency.
Our alloy expertise allows us to tailor chemistry and temper requirements to meet exact application specifications.
6061 Aluminum Castings
Our proprietary JC6061™ aluminum castings deliver forged-equivalent performance and are significantly cleaner than traditional cast products, with zero inclusions and a uniform equiaxed grain structure.
This makes 6061 ideal for:
- precision machining
- vacuum-critical environments
- structural industrial components
- semiconductor applications
The JC6061™ – T6C AnoMaxx® alloy meets the most demanding semiconductor requirements, offering:
- super-clean chemistry exceeding industry standards
- outstanding anodizing response
- excellent strength
- superior machinability
- optional refined chemical limits
356 Aluminum Castings
356 aluminum castings, available in T6 and T5 conditions, offer excellent castability, dense grain structure, strong mechanical properties, and superior machinability.
These components are commonly used for:
- seal rings
- precision industrial parts
- power generation systems
- marine equipment
- military applications
- paper processing machinery
7075 Aluminum Castings
7075 aluminum castings provide an exceptional strength-to-weight ratio for high-stress applications.
JCT’s casting process produces dense, defect-free 7075 aluminum components suitable for:
- structural applications
- subsea equipment
- load-bearing designs
- industrial processing systems
