Honed Aluminum Cylinder Tubing

• Ultra-Smooth Internal Surface: Precision honing delivers extremely fine internal finishes with roughness values down to Ra 0.2 μm, ideal for low-friction hydraulic or pneumatic use
• High-Strength Aluminum Alloy: Typically produced in 6061 or 6063 series, balancing structural rigidity with lightweight characteristics
• Close Dimensional Tolerance: Tight controls on both inner diameter and roundness-crucial for seal integrity and precise fitment
• Excellent Corrosion Resistance: Aluminum construction and optional anodizing or polishing treatments offer protection and longevity
• Thermal Stability: Maintains consistent shape and dimensions under varying temperature conditions, suitable for dynamic and high-precision assemblies
• Seamless Tubing Options: Available as seamless or extruded hollow sections to ensure continuous grain structure and optimal strength
• One-Stop Delivery: Integrates forming, honing, secondary machining, and surface finishing into a streamlined production process

• Material Options: Aluminum alloys such as 6061, 6063; other alloys available on request
• Manufacturing Method: Seamless or extruded hollow tube, followed by precision honing
• Inner Diameter Range: From approximately 10 mm up to over 200 mm, customizable per application
• Outer Diameter & Wall Thickness: Adjustable to meet strength and structural requirements
• Surface Roughness: Internal surface honed to Ra 0.2 μm or better for minimal friction
• Dimensional Tolerances: Inner diameter and roundness controlled within ±0.01 mm or tighter as needed
• Surface Finishes: Anodizing, polishing, sand-blasting, powder coating, or chemical passivation
• Secondary Operations: CNC machining, cut-to-length, threading, slotting, or specialized finishing
• Production Flexibility: Supports both prototype runs and high-volume demand with consistent quality
