Product Overview
Beilun Metal's Non-Magnetic Pure Iron Rivets are engineered specifically for applications where even the slightest magnetic interference is unacceptable. Unlike standard fasteners that can distort sensitive measurements or disrupt magnetic fields, these rivets are manufactured from high-purity, specially processed pure iron to provide reliable structural integrity while maintaining magnetic neutrality. They are the ideal choice for assembling electronics, scientific instruments, and any equipment where magnetic cleanliness is critical.
We offer these rivets in a variety of custom shapes-including round, flat, countersunk, and specialty profiles-tailored to fit your specific assembly requirements without compromising the performance of the surrounding components.

Frequently Asked Questions (FAQ)
Q1: How do you ensure the rivets are truly non-magnetic?
We start with high-purity iron and employ specific annealing and processing techniques designed to minimize ferromagnetic response. We can also perform screening tests to verify low magnetic susceptibility before shipment upon request.
Q2: Can these rivets be used in a vacuum or cleanroom environment?
A: Yes. They can be supplied with suitable cleanroom-compatible packaging and surface finishes (such as passivation) to minimize outgassing and particulate contamination.
Q3: What is the difference between "non-magnetic pure iron" and standard stainless steel fasteners?
A: While some austenitic stainless steels are weakly magnetic, their properties can vary. Our pure iron rivets are processed specifically for consistent, low magnetic permeability, offering more predictable performance in critically sensitive applications than standard stainless steel.
Q4: Do you provide certification for the non-magnetic properties?
A: We provide standard material certification (MTC). Specific magnetic permeability testing and certification can be arranged as a value-added service for qualifying orders.
Q5: What is the lead time for custom-shaped rivets?
A: For new custom shapes, the lead time is typically 6-8 weeks, which includes tooling setup and sample approval. For standard non-magnetic rivet shapes, lead time is shorter, around 3-4 weeks.
Q6: Are there limitations on the custom shapes you can produce?
A: We specialize in cold-forming processes, which are ideal for a wide range of head styles and shank geometries. We will review your design to confirm manufacturability and may suggest optimizations for performance and cost.
