Product Description

Products Features

  • 1
    Magnetic-free Characteristic
    Titanium alloy fasteners take advantage of the completely non-magnetic property of titanium metal, which makes them suitable for precision machinery and aerospace applications, avoiding magnetic interference to the equipment.
  • 2
    Austenitic Stainless Steel (e.g. 302HQ)
    Usually exhibits non-magnetic or weak magnetic properties, making it suitable for applications in electronic instruments and other scenarios.
  • 3
    Advantages of Material Properties
    Titanium alloy: Low density, high strength, strong corrosion resistance (especially suitable for seawater and chemical environments), and high temperature resistance (maintains performance at 500℃).
    Austenitic stainless steel (such as 304, 316, etc.): Enhanced in corrosion resistance by adding elements like Mo and Cu, with excellent cold working properties.
  • 4
    Processing and Usage Precautions
    Stainless steel fasteners may exhibit a slight magnetic property after cold heading due to processing stress, but this is not a problem with the material itself.
    Be vigilant against the low-quality trap of "non-magnetic and non-nickel" stainless steel. Authenticity should be determined through material certification and craftsmanship assessment.

Application

Non-magnetic fasteners, due to their unique anti-magnetic interference properties, play an irreplaceable role in precision instruments, medical equipment, aerospace and other fields.

🏥 MRI Equipment
Used for fixation of the magnetic resonance imaging system to prevent ferromagnetic materials from interfering with the uniformity of the magnetic field and to ensure imaging accuracy.
🛰️ Navigation System
Components of satellites and aircraft should be made of non-magnetic materials (such as beryllium-cobalt copper C17500) to avoid interfering with gyroscopes and magnetometers.
📡 Radar Equipment
The high-frequency signal transmission component needs to be connected through a non-magnetic connector to reduce signal distortion.
🔬 Precision Instruments
High-precision electronic measuring equipment (such as spectrometers) uses non-magnetic connectors to prevent signal drift.
⚛️ Quantum Laboratory
Superconducting quantum bits are extremely sensitive to magnetic fields. Non-magnetic fasteners (such as PEEK material) are essential components.
💨 Wind Power Equipment
Amorphous alloy bolts are used for the transformer core to reduce eddy current losses.

Frequently Asked Questions (FAQ)

Q What are non-magnetic fasteners and why are they important?
Non-magnetic fasteners are fasteners made from materials that do not exhibit magnetic properties, such as titanium alloys or austenitic stainless steels. They are critical in environments where magnetic interference could compromise equipment performance, such as in MRI machines, aerospace navigation systems, and quantum laboratories.
Q What materials are commonly used for non-magnetic fasteners?
Common materials include titanium alloys, austenitic stainless steels (such as 304, 316, 302HQ), A286, OCr21Ni6Mn9N, OCr16Ni22Mn9Mo2, PEEK, and beryllium-cobalt copper (C17500). Each material is selected based on the specific application requirements such as temperature resistance, corrosion resistance, or strength.
Q Can stainless steel fasteners become slightly magnetic after processing?
Yes. Austenitic stainless steel fasteners may exhibit slight magnetic properties after cold heading due to processing-induced stress. However, this is a result of the manufacturing process and does not indicate a change in the base material's composition. Material certification and proper craftsmanship assessment should be used to verify authenticity.
Q What are the key advantages of titanium alloy fasteners over stainless steel fasteners?
Titanium alloy fasteners offer lower density (lighter weight), higher strength-to-weight ratio, superior corrosion resistance in seawater and chemical environments, and high-temperature performance up to 500℃. These properties make them especially suitable for aerospace, marine, and high-performance industrial applications.
Q How do I verify that a non-magnetic fastener is genuine and high quality?
Authenticity and quality should be verified through official material certifications (mill certificates), third-party testing, and a thorough assessment of the manufacturing process. Be cautious of low-quality products marketed as "non-magnetic and non-nickel" stainless steel, as these claims may be misleading.
Q Which industries benefit most from non-magnetic fasteners?
Industries that benefit most include medical imaging (MRI equipment), aerospace and defense (navigation, radar systems), scientific research (quantum laboratories, spectrometers), renewable energy (wind power transformers), and any precision engineering field where magnetic interference must be strictly controlled.
