- Q: I know they stopped in 1982, but when did they start?Also for a bonus if you know when they started and stopped making Canadian pennies out of copper as well.
- The first year for the 95% copper cent was 1864. The only year between 1864 and 1982 where it wasn't copper was 1943, when it was made out of steel (the copper was considered a vital war material). From 1857 through early 1864, the cent was made out of 88% copper and 12% nickel. Before that, it was essentially pure copper (there were often impurities, depending on where they got it from). For Canadian cents, the last year for the bronze cents was 1996
- Q: Which is better to conduct heat thin or thick copper pipe?
- Conduct heat from where to where ?? In some setup it is better to have thin pipes and in another setup the reverse is right. More Precious words are needed for your question.
- Q: Nearly all the copper piping that goes to my taps (under sinks, etc) looks brown/tarnished and is very tough (I have removed some and it was not easy to bend). I have come across quite a bit of 1/2 annealed copper tubing. It is new and shiney, and quite easy to bend with my bare hands. Is this suitable to use for replacing old plumbing pipes? Is there anything I‘d need to be aware of?Thanks very much.
- just use it it will be ok
- Q: Today, just bought 2 beautiful air conditioning, take apart the box to see, connect the copper pipe only 3 meters, I rely on, too short, other brands have 5 meters, to install, you want to buy copper pipe, the United States and the United States too tyrants. The United States is too aggressive and wants to increase revenue.
- Now the most common air conditioner manufacturers original frequency of 3 meters 3.5 meters 2P 3P air conditioning cabinet cabinet 4 meters businesses did not eat you like
- Q: replacing piping in a old house, what kind of piping should i use. copper or cpvc?
- Pex then cpvc then copper last. Pex is the easiest to work with and takes less connections. Less connections means less room for errors. cpvc is also easy to work with takes more connections so make sure you glue them solid. Copper was great in its day but I feel it has done its time, time to move on to better stuff.
- Q: per pound of copper wire?
- Copper is going for around $1.70 per pound. The price varies daily, so it could be a bit more or less.
- Q: i have copper rings that turn my finger green i asked people and said that those are my toxins
- No, the green is not the result of toxins in your body coming out. Copper naturally turns green when it oxidizes. That's a fancy word for rust. Metals react with oxygen to for an oxide. If the metal is iron, then the rust is red. If it's copper, the rust is green. Your copper rings leave a green stain on your fingers because they are reacting to the water you sweat. There isn't any way to leach toxins out of the body. The body naturally eliminates some things through urine, sweat and stool. The true toxins- things like heavy metals - lead, etc, can only be removed from the body through a process called chelation. That requires some pretty heavy duty chemicals that have to be given by intravenous infusion, in the hospital, while you are monitored constantly by doctors who are experts at the process. Nothing you wear, eat or drink will do the trick. What you have is a case of copper rust staining on your skin- nothing else.
- Q: Does any one know of any sites that explains how Alaskan Natives used the metal copper many years ago?I've tried searching, but I cannot find anything.Thank you so much!
- Uses of Copper for an Alaskan Man (without any feminism offcourse in my answer...) 1) Melting Point is 1000 degree celcius approx - hence one of the easiest to melt and extract or cast 2) Copper Vessels conduct heat faster than Iron/steel etc hence good for cooking 3) Soft, so can be easily cast into hooks , and other hunting objects say spear tips etc.. Hey Stargrl, am not havin any definite sources..I'm stating the possible reasons for using copper and also what i had seen them doin when i visited Alaska a few yrs back... 4) Copper is the easiest metal that can be made into alloys , so its also useful in making other 'corrosion resistant' things..Since life is in general 'tough' in alaska,
- Q: i am trying to figure out how the atom copper is harmful to people in everyday life . so is it or is it not?
- Copper oxidation in the water supply from oxidized pipes causes copper poisoning. Symptoms Swallowing large amounts of copper may cause vomiting, abdominal pain, diarrhea, and yellow skin (jaundice). Touching large amounts of copper can result in hair discoloration (green).
