Is copper grease good to use on earthing points? What else would you use it for instead of ordinary grease? Etc.
An interesting question, but I don't know if it conducts. I usually use it on brake components - especially the pins that hold pads into calipers, which can sometimes seize into them). Otherwise, bolts and studs going tight into alloy where you think they might otherwise seize up. But I'm sure someone will know more of the pros and cons.
Many thanks I was just wondering re copper grease, I use it for the back of brake pads , pins etc and was curious of its uses.
It has anti seize characteristics, it is also hi melting point, so can be used for bolts and pins in brake callipers.
Di-electric silicone grease is available from Maplins amongst others and is used for greasing over terminals and also on spark plug boots. It does conduct electricity. Servisol Silicone Grease Tube | BuySpares
I understood its main properties were anti-seize. Some say you shouldn't use it on surfaces under rotation, bearings, wheel spindles, swinging arm bushes etc because the copper can actually cause eventual wear. I use a good general purpose grease for those jobs. I use copper slip on brake components and fasteners prone to seizure. The spray on copper grease claims it can be used for electrical connections but I've used it on battery terminals and found it ineffective. You're better off with proper electrical grease.
Check the use of Copper Grease with Alloy and Stainless, I seem to remember something about Galvanic Corrosion.
Vaseline, or petroleum jelly, is derived from oil. I was told by a time-served mechanic many years ago not to use it on rubber or plastic parts as it will eventually break them down. Silicone grease is what I use for electrical components and copper grease on all bolts, pins, or nuts I might want to undo at some later stage
Copper grease is for use on high temp stuff like exhaust bolts/studs, turbo fittings and superheater fittings. The base grease is crap and meant to burn off leaving the copper particles behind as a lubricant. For temperatures up to about 150C I prefer molycote type stuff. And silicon based for o rings with dielectric grease for electrickery
No it doesn't. That's a common misconception, it is in fact a very good insulator. Here are a few facts about silicone grease Silicone grease - Wikipedia, the free encyclopedia Dielectric Grease vs Conductive Grease
It's also why stainless steel bolts in aluminium castings can form a green deposit having got wet, through (I think) electroysis.
can confirm copper grease does not conduct as say, copper bar would - anyone with any doubt can check their own 'tub' with a multimeter. Of course almost anything can be persuaded to 'conduct' if amperage is high enough but copper grease/copper ease/copaslip not a good conductor.
I have just put two electrodes across @Chris and can confirm, he could not conduct an orchestra without further training.
or a bus for that matter. :smileys: i am going off using copper grease for caliper slides always on the back of pads and where they sit in the carrier.
that was an agree on the 'bus' thing - I can't comment or remember about the pads bit - I remember that I get fed up seeing the grease spray radially if it gets anywhere on wheel or disc bolts. People always bang on about Loctite here, Loctite there but I only use it when I really have to, and never had a problem that lead to my 'undoing' :smileys:
