Titanium alloy fasteners take advantage of the completely non-magnetic property of titanium metal, making them suitable for precision machinery and aerospace applications, avoiding magnetic interference to the equipment.
Usually exhibits non-magnetic or weak magnetic properties, making it suitable for applications in electronic instruments and other scenarios.
Titanium alloy: Low density, high strength, strong corrosion resistance (especially seawater and chemical environments), and high temperature resistance up to 500℃.
Austenitic stainless steel: Enhanced corrosion resistance (304, 316) with elements like Mo and Cu, offering excellent cold working properties.
Stainless steel fasteners may exhibit slight magnetic properties after cold heading due to processing stress; this is not a material defect. Verify authenticity through certification rather than simple magnetic tests.
Fixation of magnetic resonance imaging systems to prevent field interference and ensure imaging accuracy.
Satellite and aircraft components using materials like beryllium-cobalt copper to avoid gyroscope interference.
High-frequency signal transmission components connected through non-magnetic connectors to reduce distortion.
Measuring equipment like spectrometers utilize non-magnetic connectors to prevent signal drift.
Superconducting quantum bits are sensitive to fields; non-magnetic PEEK materials are essential here.
Amorphous alloy bolts are used for transformer cores to effectively reduce eddy current losses.
