I know this sounds like a ridiculous request, but it is for a project I'm working on that requires high grade copper but only a little bit. Happy to pay a decent price for a copper bar. Does anybody have a small piece they'd be willing to sell? Thanks guys.
Streetips uses Copper pipe as its so pure, to bring 99% silver out of solution. Ive never bought any as its expensive due to Australia's GST.
If you just want to experiment, precipitation from solution with pipe is fine. Anything further you should be using solid bar or very thick plate, i use 60mm thick x 200mm. Small bits will end up in your precipitate if you use pipe and cause contamination. Or to skip all the waste issues and boiling of must be pure water, buchner filters etc, use silver chloride method.
Yeah, cant use aussie copper coins as they are an alloy which produces unwanted impurities and will precipitate other metals from solution in the reactivity series and also produce unwanted chlorides which stick to the copper surface disabling the reaction.
Most electrical appliances with motors (such as vacuums, drills and washing machines) have copper wire in the motors that you can often get for nothing.
Go to any large electrical company in your area 20 plus employees and ask for copper Busbar Generally 5mm thick and comes in off cut lengths. Thats what I do and works a treat
I'll spill the beans on what I'm doing, I guess. I'm preparing to propose in a rather different way. My girlfriend and I never agree on design of anything (furniture, art, etc), so I'm proposing with all the raw components of a ring and I've lined up a jeweller to make the whole thing from scratch after we design it together. Hoping to get a small film of the experience as well. I've already lined up the rock, already have gold and silver, but want to get all components of multiple gold colours so she can choose. High purity is pretty important, obviously. I'm actually an electrician and have access to a bunch of offcuts, obviously, but it would look like crap, proposing with busbar. Haha.
An electrician that cant get hold of Copper!,thats a new one lol. Good luck with the proposal, sounds like an awesome idea and project!! Good tidings,God speed RB
Given that I'm not proposing with a ring, I think that what I do use needs to be tidy, that's all. Plus cable is all coated to suppress corrosion. Thanks, I've had this plan since before I met this lovely lady, many years ago. I think I'd better use it before someone I've mentioned it to does it first. Haha.
Hi Top, if you are still looking, i got some copper bullion. But you need to buy the whole 10 or 12 oz of it, but i do you a good deal just to help you out. Send me a pm if you are still looking. Cheers
Was not aware of this then put the 1 & 2 cent coins under an XRF and did some copper Pennys. Spot on not 100% pure copper!
16mm,25mm,32mm,50mm,70mm,95mm,120mm XLPE or SDI would have no coating on the copper cores if stripped out You could also use small domestic buss bars etc

They are also used to connect high voltage equipment at electrical switchyards, and low voltage equipment in battery banks.
