Aluminum Semi Hollow Rivets

Aluminum semi hollow rivets are what you use when weight is the problem.

Steel is strong but heavy. Brass looks good but adds mass. Copper conducts but weighs you down. If your product moves, flies, or gets carried – every gram matters.

Aluminum solves that. One‑third the weight of steel. Non‑magnetic. Naturally corrosion‑resistant. And because it is a semi hollow design, you still get 70% less setting force than a solid rivet.

Aluminum vs. Other Materials – Where Aluminum Wins

Which Alloy – 1100, 5052, or 5056?

If you are not sure, 5052 is the safe choice for most applications.

One Real Application – Ultralight Camping Cot

A manufacturer of ultralight camping cots needed to reduce weight. The frame was already optimized – the only place left was the fasteners. Steel rivets were adding unnecessary mass.

We supplied 5052 aluminum semi hollow rivets – 4.0mm shank, 7.0mm round head, 8.0mm barrel length, clear anodized. Weight saving: 65%. Setting force dropped from 3.5 tons to 1.0 ton. No deformation of the thin‑wall tubing. The customer tested 1,000 rivets across 500 cots. After 5,000 folding cycles with a 100kg load, zero failures. They now order 250,000 pieces annually.

What Can Go Wrong – And How We Prevent It

Inside Our Production – 45 Machines, 10+ Years Experience

We manufacture aluminum semi hollow rivets on 45 cold‑heading machines in our Dongguan facility. Diameters from 0.8mm to 10mm. Standard heads and custom shapes.

Who makes them: Senior technicians with an average of 10+ years of cold‑heading experience.

What we check: Cavity depth, head geometry, shank diameter, hardness – every batch.

Production speed: Up to 400 pieces per minute.

What Our Customers Say – Real Feedback

We let our customers speak for us. The images above show real feedback from manufacturers who have used our aluminum semi hollow rivets in their production lines – from camping equipment makers to drone builders to automotive lightweighting engineers.

They come back to us for the same reasons:

Weight savings that matter – One‑third the weight of steel, delivered on every batch.

Consistent quality – Cavity depth, head geometry, and dimensions match their drawings.

Reliable delivery – Samples ship in 5–7 days, production on schedule.

Two Questions We Answer Often

Q: "Can I get samples before ordering production quantities?"

A: Yes. Standard specs: free, you pay shipping. Custom sizes: contact us for sample cost and lead time.

Q: "Are aluminum semi hollow rivets strong enough to replace steel in structural applications?"

A: It depends on the load. Aluminum semi hollow rivets offer 80–90% of solid rivet strength, but aluminum itself has lower tensile strength than steel (90–350 MPa vs 400–500 MPa). For lightweight structural applications – drones, camping equipment, automotive interiors, aerospace non‑critical assemblies – aluminum is more than sufficient. For heavy‑duty structural loads, stick with steel. If you are unsure, send us your load requirements and we will calculate whether aluminum works for your application.
