Custom Machining Aluminum Stainless Steel CNC Machined Spacers Rings

Product details

Technical Specifications

ParameterKey Details
MaterialAluminum alloy (6061-T6/7075-T6: lightweight, corrosion-resistant); Carbon steel (1045: cost-effective for general industrial use); Stainless steel (304/316/316L: superior corrosion resistance for harsh environments)
ProcessingCNC precision turning, milling, laser cutting, stamping, deburring, surface treatment; custom thickness/hole patterns for specialized assembly needs
ToleranceDimensional tolerance ±0.005–±0.02mm; flatness ≤0.01mm; hole position tolerance ≤0.015mm (ensures precise alignment in mechanical assemblies)
Size RangeInner diameter: 2–200mm; outer diameter: 5–300mm; thickness: 0.1–20mm; custom shapes (circular, square, rectangular, irregular) and multi-hole designs available
Surface FinishAluminum: Anodizing (black/silver/colorful, wear-resistant), sandblasting; Carbon steel: Zinc plating, galvanizing, black oxide coating (rust-proof); Stainless steel: Passivation, electropolishing, mirror polishing (Ra ≤0.2μm for hygienic applications)
Mechanical PropertiesAluminum washers: Lightweight (density 2.7g/cm³), good electrical conductivity; Carbon steel: High tensile strength (≥550 MPa), suitable for high-load applications; Stainless steel: Corrosion/heat resistance (-200°C to 870°C), ideal for chemical/water treatment systems
Application CompatibilityPre-drilled holes (M2–M50) for bolts/screws; compatible with hydraulic/pneumatic systems, robotic assemblies, automotive engines, electronic enclosures, and industrial machinery

Application Scenarios

  • Industrial Machinery Assembly: Steel/stainless steel spacer rings for gearboxes, conveyor systems, and motor mounts, ensuring precise component spacing and reducing vibration
  • Electronics & Electrical Equipment: Aluminum washers for PCB mounting, battery pack assemblies, and sensor fixtures, leveraging lightweight design and electrical insulation
  • Hydraulic/Pneumatic Systems: 316 stainless steel washer spacers for valve fittings, pipeline connections, and cylinder seals, resisting corrosion from fluids and gases
  • Automotive & Aerospace: 7075-T6 aluminum spacers for aircraft interiors, EV battery frames, and engine components, balancing high strength and weight reduction
  • Custom Mechanical Prototypes: Tailored washer/spacer rings for DIY projects, R&D equipment, and specialized automation devices, matching unique assembly dimensions
