Aluminum vs Copper crush washers

[sojahseh]

Is there any reason to not use copper sealing / crush washers on the various areas of the motor? Banjo bolts etc?

I've been using the copper ones, and I'm wondering if it's a bad idea.


Thanks in advance.

I would use aluminum crush washers if the two mating surfaces are aluminum. If the surfaces are steel, I would copper.
