Re-rivetting SS fixtures to aluminium mast

[anoccasionalyachtsman]

I know that Kemp were using Monel 40 years ago, so 'phoned Selden and they tell me that they have since 1965!

I was hoping for "Monel" to come up - I have an Air-Riveter - but what exactly are the properties of Monel Rivets - and why are they the choice?

What does "Monel" mean - in terms of metallurgy?
I apologise for my ignorance on the subject.

Monel metal is copper/nickel alloy with high tensile strength and low corrosion.
It has the additional advantage of being suitable for use with both stainless steel and aluminium, so is the ideal choice for riveting these materials together.
Monel rivets do require a fair amount of force so heavy duty tools are needed to use them.

Thanks for the info. I am impressed.
