Copper grease?

[Martini-night]

Copper grease goes here on a steel frame? if I can remember? Has been 25+ years since I last assembled a bike.. plus I couldn't get a straight answer on Google

All of those will be fine for copper anti seize.
You basically gotta think of it as not a grease, it doesnt lubricate. All it does is keep two surfaces from bonding together.
So you only want to use it on components that dont potentially move relative to eachother. Pretty much anywhere but in bearings.

Thanks

I'm not sure that it is a good idea to use copper grease with aluminium.

Hi, it's a 1991 old steel frame.Not aluminium. Just been powder coated

Yes but I assume you are using aluminium seat posts and stems. Just use normal grease with those. Copper grease will be fine in the BB though.

Wouldn’t be using it anywhere on a bike to be honest. I’d just be using a good quality waterproof grease. I also wouldn’t be using anything on headset cups. I’d just be pressing them in dry.

Yes, correct. Seat post is aluminium and stem us also aluminium. Thanks

Copper grease isn't necessary, and it's toxic.
Steel to steel non-moving parts is acceptable.
There's a certain style of bike owner overkeen with the copper though.

Yup that's what I do.

Probably teaching how to suck eggs but the reason for grease on stems and seatposts is to put a layer between the aluminium and steel since in contact they create a galvanic reaction which causes corrosion and leads to the stuck stem or seatpost scenario that most of us are unfortunately familiar with when renovating old bikes (although never with our own carefully maintained bikes of course). Copper and aluminium also create galvanic reactions together.

Steel on steel, no galvanic reaction but you just need something to keep the water out to prevent rust.

Ordinary grease will do both these jobs adequately on a bike.
