Product: Oxygen-free copper busbar and copper bar with high conductivity
Type Specifications: T2, TU1, TU2, TAg
Copper busbar is a strip or bar of copper that conducts electricity, often produced with high purity oxygen-free copper ingot through extrusion and drawing processes, usually used in high and low voltage electrical equipment, switch contact, electrical distribution equipment, and bus slot, etc.

- Q: is re piping better then epoxy for copper plumbing?
- There is an epoxy for copper pipe, but it does not work as advertised. Repipe, it's cheaper in the long run.
- Q: Why is the air conditioning copper tube again become "air conditioning purple copper tube"?
- Because copper has good ductility, it can be bent, so it is used in the pipeline. Brass, however, is of high hardness, brittle and easily broken. So, in the air conditioner, it is usually used as the connecting head.
- Q: We heated purified copper powder in a crucible over a hot plate (while continuosly stirring) the result, the powder turned black.What can be the purpose of this experiment? Is this correct: To determine whether there is a chemical reaction when Copper powder is heated?
- Copper forms a black oxide, CuO, but because it is relatively unreactive, it takes a lot of heat to make it oxidize. (It also forms a red oxide, Cu?O, but not under the oxidizing conditions of the atmosphere.)
- Q: How does the molecular structure of hydrated copper sulphate look like , its the only compound having all for types of chemical bond.

- Q: why does copper look silver inside ,,well what i mean is like when i have a piece of copper plumber pipe and ill scratch it deep, the scratch its self looks kinds silver or chrome ,even when you scratch wire ,,why is that, if its a copper pipe shouldnt the scratch stay copper colored ------and why do some copper peices look dull & bumpy and others are smooth and shiny
- your copper pipe isn't all copper. Copper is pretty expensive, not very tough and pretty heavy, it wouldn't make much sense making a plumbing pipe all out of copper. Your pipe will probably be some other metal like steel or so and then coated with copper, so that it doesn't corrode. Copper looks copper colored all the way through. I could imagine the opposite, if you have a piece of badly corroded copper, it will be pretty dark on the outside but when you scratch it, it will become very clear and bright copper color.
- Q: I'm pretty sure I just got a copper quarter for change from the airport. It's year is 1981. How much could it be worth? How do I clean it to make sure it's not just rusted without damaging it or reducing the value?
- A copper quarter is worth ...slightly less than 25 cents. After the bicentennial coins in 1976, quarters, half dollars and dollar coins were made of 91.67% copper and 8.33% nickel composition for general circulation. Somebody worked quite diligently to remove the silver color for reasons that only he/she knows. Your quarter is the same as every other coin of it's type, except yours has been purposely defaced. It may look neat, but it is not valuable.
- Q: When I smelting copper, I noticed that, the melting point is about 2000 degrees f. and a propane torch gives out 3000 degrees f., why isn't the copper melting?
- Copper is one of the better thermal conductors, if you are heating a small piece of copper (such as a wire), it should melt. However, if you are heating a large object, expect the process to take a while (if it melts at all). Due to the high thermal conductivity, you are actually heating the entire thing using a small torch. Also, with the small difference in temperature between the flame temperature and the metal melting point, the speed of heat dissipation may exceed the heating. You could try using a hotter welding torch with acetylene fuel.
- Q: Please help! I want to know how does the copper get in to the blood. Do we it some type of food or something. I don't want to know what the blood actually taste like, to me it taste something like metal. So please help!
- Copper gets into your blood the same way all vitamins, minerals and food does through the gut. Copper is found in small doses in a lot of food. The metallic taste you describe is iron the main constituent of haemoglobin which gives blood the red colour and enables it to carry oxygen around the body. Our blood is not copper based - if it was it would be blue like a lobster's blood.
- Q: what diseases or problems could occur if copper isnt included in a persons diet?what is the name of this mineral deficiency?what are the symptoms of this?What are the long term effects?is the deficiency reversable or does it do permanent damage to the body?
- Symptoms of copper deficiency include fatigue, bleeding under the skin, damage to blood vessels, and an enlarged heart. Anemia is common, and the number of white blood cells is decreased. The diagnosis of copper deficiency is based on symptoms and on blood tests that detect low levels of copper and ceruloplasmin (a protein that contains copper). Copper deficiency is treated with a copper supplement.
