High Strength Pure Iron Rivet
Custom‑Made from Our High‑Purity Iron | Full Batch Composition Reports Available
Product Overview
Pure iron rivets are traditionally softer than steel rivets, which limits their use in load‑bearing applications. Our high strength pure iron rivets overcome this limitation through a combination of:
Controlled purity – ultra‑low carbon and impurities to enable consistent work hardening
Cold heading or machining – precise forming that maximizes grain flow and mechanical strength
Optional heat treatment – customized annealing or strain aging to achieve target tensile strength
Because we produce the pure iron raw material ourselves (from electrolytic refining to billet, rod, and final rivet), we have complete flexibility to adjust chemistry for your application – whether you need extra‑low carbon for magnetic softness, or trace elements to enhance strength without losing purity.
Every batch is accompanied by a COA showing actual composition (Fe, C, Si, Mn, P, S, etc.) and, upon request, mechanical test results (tensile, shear, hardness).
Key Features
| Feature | Benefit |
|---|---|
| High strength | Achieves tensile strength up to 400–500 MPa through work hardening |
| Made from our own pure iron | Full control over chemistry – we adjust composition per your requirements |
| Custom chemical composition | We produce rivets to your specified element limits (e.g., C≤0.002%, S≤0.003%, etc.) |
| Batch‑specific COA | Each shipment includes a Certificate of Analysis for that exact batch |
| Custom dimensions | Diameter 2–20 mm, length 5–150 mm, any head type (round, countersunk, flat, large flange) |
| Good ductility | Rivet expands uniformly without cracking during setting |
| Corrosion resistant base | Pure iron can be plated, painted, or used as‑is for clean environments |
| Factory direct | No middleman – competitive pricing, short lead times |
Frequently Asked Questions
Q: What does "high strength" mean for a pure iron rivet?
A: Our rivets achieve tensile strength of 380–520 MPa through cold heading and optional strain aging. This is significantly higher than standard pure iron rivets (which may be only 250 300 MPa) and approaches low carbon steel rivets, while retaining the purity and magnetic characteristics of iron.
Q: Do you provide a Certificate of Analysis for every batch?
A: Absolutely. Each batch (melt) is tested, and the COA is shipped with the rivets. You can match every box to a specific heat number. We can also send an advance copy for your approval.
Q: What head styles are available?
A: We support round head (dome), flat countersunk (flat head), truss head, large flange head, custom embossed, and more. Send your drawing or sample.
Q: Can these rivets be used outdoors?
A: Pure iron rusts in humid environments. For outdoor or corrosive service, we recommend plating (zinc, tin, nickel) or painting. We can supply pre plated rivets – please specify.
