Aluminium – Lightweight with good corrosion resistance.
Steel – Stronger than Aluminium with a “flash” coating of Zinc. Low corrosion resistance.
Stainless Steel A2 – Good Strength and excellent corrosion resistance.
Stainless Steel A4 – Good Strength and increased corrosion resistance
Copper – Relatively soft. Excellent corrosion resistance and conductivity.
Monel – The strongest blind rivet material with excellent corrosion resistance and conductivity. Also excellent high temperature suitability.
Material USAGE GUIDE.
Galvanic Corrosion • When dissimilar metals come into contact in the presence of an electrolyte, a galvanic action occurs which corrodes one metal at a faster rate and the other more slowly. This phenomenon can cause major riveted joint failures and care must be taken to avoid the occurrence. The following table is a guide.
|RIVET MATERIAL↓||Aluminium||Coated Steel||Stainless Steel||Copper||Brass|
|NO||Incompatible – Avoid contact with each other|
|CARE||Use with care. Painting metals will help|
1) Select materials that are as close together as possible in the Galvanic
2) Provide a barrier between the two metals, such as paint, non-metallic
washer or gaskets
3) Design the fastener as the cathode so the cathodic area is small as
compared to the anodic area
4) Use a metallic finish on the fastener that is close on the chart to the
SPECIALITY BLIND RIVETS
The grooved blind rivet has been specially developed to attach hard materials to a fibrous substrate (e.g. wood or plastic) in situations where the hole does not go all the way through (blind hole) and the connection is established in the hole itself. The mandrel head is mechanically retained in the body. Perfect for combining metal with wood (flight cases).
