Product introduction

Manufactured from high-quality Permalloy and finished with ultra-precision mirror-polishing, our components achieve a flawless surface. Designed for critical high-tech fields, they provide superior magnetic shielding, exceptional corrosion resistance, and a refined industrial aesthetic.

Core Features:

1. Ultimate Mirror Finish & Stress-Free Surface
Through multiple stages of rough grinding, fine polishing, and finishing, the product achieves a surface roughness (Ra) of 0.05μm or less, reaching a true mirror-grade standard. This high level of smoothness not only enhances visual appeal but, more importantly, eliminates micro-surface mechanical stress concentration points. It significantly improves the material's fatigue resistance and micro-crack resistance under harsh conditions, effectively preventing the decline in magnetic permeability caused by uneven internal stress distribution within the magnetic material.

2. Superior Magnetic Shielding Effectiveness (High Permeability)
Utilizing a high-nickel (approx. 80%) Permalloy material, our products possess an exceptionally high initial permeability (μi) and maximum permeability (μmax). This structural design effectively absorbs and redirects external stray magnetic fields, creating a nearly magnetically "quiet" space for internal precision electronic components, ensuring stable operation of equipment in weak magnetic field environments.

Primary Applications:

• High-End Electronics & Sensors: Used as housings or liners for precision magnetoresistive sensors, Hall effect elements, and fluxgate sensors to eliminate interference from the Earth's magnetic field and environmental stray fields.
  

  
  

• Medical Imaging Equipment (MRI/NMR): Acts as a localized magnetic shielding component to protect sensitive electronic circuits and prevent external interference from affecting imaging quality.
  

  
  

• Aerospace & Defense: Serves as magnetic shielding covers for electronic      instrument cabins in spacecraft, resisting magnetic interference caused by      space radiation.
  

  
  

• Precision Measuring Instruments: Applied in high-precision current transformers and shielding partitions for non-contact measurement equipment, ensuring accurate acquisition of weak signals.
  

  
  

• Semiconductor Manufacturing Equipment: Used as internal shielding components in critical vacuum chambers of equipment such as electron beam lithography machines and ion implanters.
