Why Aluminum 6262 performs well in precision parts
Aluminum 6262 is engineered with lead and bismuth additions that improve chip breaking and surface finish during high-speed machining. We use the alloy’s free-machining behavior to support efficient turning, turn-mill work, and repeatable production of small mechanical components.
Precision turning
Controlled chip evacuation supports high-speed CNC turning and turn-mill operations.
Thread integrity
Clean, accurate threads for connectors, fasteners, pins, and other compact parts.
Surface finish
A strong as-machined finish option for parts with cosmetic or functional requirements.
Batch consistency
Stable machining behavior helps maintain repeatability across large runs of small parts.
CNC capabilities
Machining capacity built around aluminum
Our 3-axis, 4-axis, and 5-axis equipment is optimized for aluminum alloys, from detailed prototypes to production programs requiring stable cycle times and repeatable quality.

Built for demanding components
From precision turned parts to complex housings
Enclosures and housings
Precision-fitted housings for electronics and industrial controllers.
Heat sinks
Cooling plates and complex fin designs for thermal management.
Structural components
Brackets, frames, and plates for robotics and automation systems.
6262 turned parts
Fasteners, spacers, shafts, and connector bodies with clean threads.
Optical mounts
High-precision components requiring strict flatness and parallelism.
Process control
Engineering discipline for stable aluminum production
Aluminum machining requires careful heat management, chip evacuation, workholding, and stress control. Our aluminum-only focus allows the team to refine these details for each component and production volume.
Deformation control
Specialized workholding and staged machining strategies minimize distortion in thin-wall and deep-pocket parts.
Stress relief
Machining strategies help preserve flatness and parallelism in large plates and structural components.
Cosmetic handling
Controlled handling helps protect finished parts from scratches and dings.
Integrated finishing
Surface treatment options for functional and visual requirements
As machined
Natural finish with controlled tool marks.
Bead blasting
Uniform matte finish, suitable for preparing surfaces for anodizing.
Anodizing
Clear, black, and color anodizing for corrosion resistance and aesthetics.
Hard anodizing
Increased wear resistance and surface hardness for demanding applications.
Secondary finishes
Powder coating, chemical film, and chromate conversion.
