Ground Connector Blind Rivets

Blind Rivet Material Combinations

Rivet Body

Aluminium Rivets – Lightweight with good corrosion resistance.

Steel Rivets – Stronger than Aluminium with a “flash” coating of Zinc. Low corrosion resistance.

Stainless Steel A2 Rivets – Good Strength and excellent corrosion resistance.

Stainless Steel Rivets A4 – Good Strength and increased corrosion resistance

Copper Rivets – Relatively soft. Excellent corrosion resistance and conductivity.

Monel Rivets – 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.

	METAL JOINED
RIVET MATERIAL↓	Aluminium	Coated Steel	Stainless Steel	Copper	Brass
Aluminium Rivets	YES	CARE	NO	NO	NO
Coated Steel Rivets	NO	YES	NO	NO	NO
Stainless Steel Rivets	CARE	CARE	YES	YES	YES
Copper Rivets	NO	NO	YES	YES	YES
Monel Rivets	NO	NO	YES	YES	YES
YES	Compatible
NO	Incompatible – Avoid contact with each other
CARE	Use with care. Painting metals will help

Hence,

1) Select materials that are as close together as possible in the Galvanic Series Chart
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 mating material
