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 slight magnetic properties after cold heading due to processing stress — this is not a defect of 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

High-frequency signal transmission components need to be connected through non-magnetic connectors to reduce signal distortion.

🔬

Precision Instruments

High-precision electronic measuring equipment (such as spectrometers) uses non-magnetic connectors to prevent signal drift.

⚛️

Frequently Asked Questions (FAQ)

Q What are non-magnetic fasteners and why are they important?

Non-magnetic fasteners are hardware components made from materials that do not exhibit magnetic properties, such as titanium alloys and austenitic stainless steels (e.g., 304, 316, A286). They are critical in applications where magnetic interference can compromise equipment accuracy, safety, or functionality — such as MRI machines, 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 302HQ, 304, 316, A286, OCr21Ni6Mn9N, OCr16Ni22Mn9Mo2, 1.4436, 1.498), beryllium-cobalt copper (C17500), and PEEK (Polyether ether ketone). Each material is selected based on the specific performance requirements of the application environment.

Q Why do stainless steel fasteners sometimes become slightly magnetic after processing?

During cold heading or other cold-working processes, stainless steel can undergo a phase transformation — austenite partially converts to martensite due to mechanical stress. This introduces slight magnetic properties. It is a processing-induced phenomenon and does not indicate a material defect. The original non-magnetic characteristic of the alloy is preserved in its base composition.

Q What is the difference between titanium alloy fasteners and austenitic stainless steel fasteners?

Titanium alloy fasteners offer lower density, higher strength-to-weight ratio, exceptional corrosion resistance (particularly in seawater and chemical environments), and high-temperature stability up to 500℃. Austenitic stainless steel fasteners (e.g., 304, 316) provide excellent cold working properties and enhanced corrosion resistance through alloying elements such as molybdenum (Mo) and copper (Cu), making them more cost-effective for general industrial use.

Q How can I verify the authenticity of non-magnetic stainless steel fasteners?

Always request material certification (mill test reports) and verify the chemical composition against recognized standards. Craftsmanship assessment, including hardness testing and microstructure analysis, can also help confirm authenticity. Be cautious of suppliers claiming "non-magnetic and non-nickel" stainless steel, as this is often a sign of low-quality or counterfeit materials.

Q In which industries are non-magnetic fasteners most widely used?

Non-magnetic fasteners are most widely used in the medical industry (MRI and diagnostic imaging equipment), aerospace and defense (navigation systems, radar, satellites), scientific research (quantum laboratories, spectrometers), and energy sectors (wind power transformers). Any field requiring high electromagnetic compatibility (EMC) and precision performance benefits from non-magnetic fastener solutions.
