Product Description

Precision-Machined Non-Magnetic Alloy Positioning & Bearing Components for Magnetic-Sensitive Machinery

Precision-Machined Non-Magnetic Alloy Positioning & Bearing Components for Magnetic-Sensitive Machinery

WC-Ni alloy with µ < 1.002 permeability, 89-92 HRA hardness, and ±0.001mm OD tolerance for semiconductor, medical, and aerospace applications. Custom diameters up to 300mm.

Our Precision-Machined Non-Magnetic Alloy Outer Diameter (OD) Rings are engineered specifically to overcome these challenges. Manufactured from advanced WC-Ni (Tungsten Carbide-Nickel) alloy and other specialized non-ferrous materials, these precision annular components deliver the essential combination of absolute magnetic neutrality, micron-level OD tolerance, and outstanding dimensional stability for the most demanding metalworking and precision assembly applications.

Key Performance Benefits

Recent breakthroughs in WC-Ni sintered ring technology have achieved magnetic permeability consistently below 1.002, providing:

  • Zero magnetic signature – no disruption to sensitive electronic or magnetic systems
  • No ferrous particle attraction, preventing contamination in cleanroom environments
  • Complete compatibility with MRI-adjacent equipment, wafer handling stages, and precision measurement systems
  • Safe integration into medical, semiconductor, and aerospace machinery
