high current bolted connection paste
high current bolted connection paste
(OP)
We have some tinned lugs bolted to copper blocks using bronze bolts and beryllium copper belleville washers, but SS bellevilles may have to be substituted.
A low load test is planned that will last a few weeks.
Future full load testing will likely be done with different lugs.
Connection Options discussed so far:
- torque them up clean and dry
- apply dielectric grease and torque
- apply electrolytic grease and torque
- rub or burnish with dry silver powder/flake, and torque
Internet searches find products and methods for aluminum and aluminum>copper connections, but generally suggest copper>tin is OK by itself.

I figure if I'm supposed to put some dielectric grease on my spark plug connections we probably ought to do SOMEthing.
update - the copper blocks were supposed to be silver plated, and now must have a green patina cleaned off before plating
