Description
These Dome Head Open Blind Rivets in Aluminium are engineered for reliable fastening where strength, corrosion resistance, and a neat finish are essential. Constructed entirely from AIMg2.5 aluminium alloy, both the rivet body and mandrel provide a lightweight solution that resists rust and environmental wear, making them ideal for indoor and outdoor applications.
The dome head design ensures a smooth, low-profile finish once installed, while the open blind rivet style allows for quick and efficient fastening from one side of the workpiece. This makes them particularly useful in situations where rear access is restricted or impossible.
Installation is straightforward using standard hand or power riveters, and once set, the rivet provides a secure, vibration-resistant joint that won’t loosen over time. The aluminium construction ensures ease of handling while maintaining the strength required for demanding applications.
Guidance on Material Compatibility
When selecting rivets, material compatibility is critical to ensure long-term performance and prevent corrosion. Aluminium rivets, like your Dome Head Open Blind Rivet Aluminium/Aluminium – Pack of 50, are designed to work best in certain environments:
✅ Best Materials to Use With Aluminium Rivets
- Aluminium sheets and profiles – Perfect match, as rivet and substrate share similar electrochemical properties.
- Plastics and composites – Lightweight and non-reactive, making aluminium rivets ideal for fastening without risk of corrosion.
- Soft alloys (e.g., magnesium alloys) – Compatible with aluminium rivets, offering strength without galvanic reaction.
- Light-duty applications – Automotive trim, roofing, cladding, and general fabrication where corrosion resistance and low weight are priorities.
❌ Materials to Avoid With Aluminium Rivets
- Stainless steel – Creates a galvanic couple with aluminium, leading to rapid corrosion when exposed to moisture.
- Copper or brass – Highly reactive with aluminium, accelerating galvanic corrosion and weakening joints.
- Carbon steel – Stronger but electrochemically incompatible, risking rust and corrosion at the joint.
- Marine environments with dissimilar metals – Saltwater accelerates galvanic corrosion, so aluminium rivets should only be used with aluminium or non-reactive substrates.
Why Compatibility Matters
When dissimilar metals are joined, galvanic corrosion occurs if they have different electrochemical potentials. Aluminium rivets are excellent for lightweight, corrosion-resistant fastening, but pairing them with incompatible metals can shorten service life and compromise structural integrity.
