High Purity High Density Copper Alloy Bar Application:

Produced by low-vacuum copper smelting casting technology with its intellectual property right; high density and high purity product with low hydrogen and oxygen content, usually processed into copper products of various shapes and widely applied in steelmaking, electric power, shipbuilding, and machinery sectors

Q:How copper sulphate is prodused in industries with copper and sulphuric acid? If any catalyst is used what is that and at what tempertatuure?: Copper sulfate can be made by the action of sulfuric acid on a variety of copper(II) compounds, for example copper(II) oxide. It may also be prepared by electrolyzing sulfuric acid, using copper electrodes.

Q:Who knows the brands , models and years of the heaters with copper liners? People just want to know!: I hope those people aren't the same people who have been stealing copper downspouts from churches. The other people just want to know about that.

Q:I have some Wardley Shrimp Pellets and I see copper sulfate in the ingredients...won't this harm my inverts? (Blue lobster, fiddler crabs, dwarf shrimp): It is only a trace amount but I would avoid any copper with inverts. It does not take much to kill snails for example. Invertebrates, like other living things, do need a trace of copper in their food. Some of them even use copper instead of iron in their blood, which makes it blue or even green instead of red. It is common to simplify and say all invertebrates have copper based blood. The naturally present copper in foods is the safe way to obtain what is needed. Using a food with copper supplemented is unnecessary. Copper supplements, like copper containing medications, can precipitate in the aquarium and build up. Then with some shift in water parameters such as pH, temperature, or hardness, all of the stored up copper goes back into solution. There would be no problems with the copper additive until there was something else handy to blame it on. You would have just done a partial water change and automatically guess that the water company put some toxic chemical treatment in the water supply. If you want to see what a little copper sulfate can do, look at the pictures in this link below. It can change the color of hardened concrete.

Q:Why is some copper wire from say a winding in an electric motor bright gold and other like speaker wire is white. are they both copper or is one copper with an alloy?: copper wire is well copper colored. Speaker wire that is silver is an alloy. Copper is expensive. currently the amount of copper in a penny is worth more than $0.02. so if you were to sell 100 pennies you would get $2 plus for the copper. Enough so that the feds recently made this illegal. The color is there so that you can tell the polarity of the current running through the wire.

Q:Could someone just explain to me why the zinc is the negative terminal and not the copper? thanks: Because zinc is a more active metal than copper. Being more active, it is more likely to be oxidized (lose electrons). The copper ions at the other terminal are more likely to be reduced to copper metal (and when they do, they gain electrons).

Q:Why is copper used for: coins,pipes,& saucepans?eg. good conductor of electricity.Thanks :): copper is (was) a cheap and abundant metal with very high conductivity for both electricity and heat, it offers relatively low resistance also. It's basically efficient and cheap. Another useful property of it is its ease of use for electroplating at low voltages.

Q:Really dont know why but i was wondering is copper going to be the next BIG gold or silver Boom: Turtles is correct, copper is a commodity. It doesn't have the same store of wealth quality that gold and silver to a lesser extent have and probably never will. The only way that copper is going to boom is if demand rises significantly and given that the Chinese housing market will probably crash in the next couple years, US new home construction won't rebound nearly enough to cover, and there aren't a lot of new industrial uses coming to market in the near future I don't see a boom anytime soon.

Q:I have a culminating activity to do and I wanna know which one is better. If you got the information on it please send me the source. I would be appreciated.: have you not watched the news lately re: the people in Flint, MI and the problems they are having with lead pipes ??
