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:in plumbing what are three finishes applied to copper pipe?
- In plumbing, finishes are not applied to copper pipe. There is no reason to apply anything.
- Q:My single story house was built in 1955 on a slab. My stub outs are iron pipe. What kind of plumbing pipe is running through my slab, iron or copper? I always thought it was copper, but why the iron stub outs?The reason I ask is that I‘m going to change my angle stop valves and want to know if I need to apply much counter torque when I remove them from the 1/2 MIP stub.Thanks!!
- The purpose of two rotors is to dissipate heat better. You'll also notice that motorcycle rotors are typically vented, and increasingly wave (the outer edge of the rotor is a wave vs. just a round disk) all of these changes increase the surface area of the rotor. More surface area more heat released into the air on braking. Besides the number of rotors and pads, you also have to consider the size of the rotors. Frankly, most Motorcycle brakes are overkill for the type of riding (most stock bikes have adequate braking systems to be used on the track) - maybe its cheap enough to make the brakes on a bike much better than a car, and the safety benefit outweighs the cost anyway? Heat is generated from friction when the pads rub against the rotor when the brakes are applied. The more the bike weighs, the more heat will be generated when stopping. Smaller, lighter bikes may not generate as much heat when braking, so they only use one set of rotors in front. I don't know about Evo or Honda brakes. There are lots of reasons why the designers may feel one brake system is needed on a vehicle vs another. Besides the number and size of the pads, the size of disc, and the material are also considerations. If the brakes don't dissipate enough heat, you'll eventually wind up with warped rotors, and reduced brake life.
- Q:If the air conditioner is re assembled, will it damage the copper tube?
- Influential。 Depending on the location of the copper tubes, the effect on the air conditioning is different.When the air conditioner indoor and outdoor machine connecting copper pipe bend, air conditioning and refrigeration system piping "pressure loss" will become large, from the compressor working point, variable pressure loss large led directly to the air conditioning compressor capacity output of small systems, such as air conditioning compressor is 2 horsepower capacity, due to internal and external connecting pipe bending machine fold to a certain extent lead to evaporation pressure air conditioning system is reduced, the compressor habit pressure is reduced, the corresponding proportion of the output capacity of the compressor capacity may become smaller, 1.8 horses or even lower number of horses compressor value.When the air conditioner indoor and outdoor machine bending connecting copper pipe to a certain extent, if we can repair the best, it can not be repaired, can only replace the connecting copper pipe or the bending place on both sides are connected by pipe cut to brazing.
- Q:i want to treat my marine fish with copper in a hospital tank (they have whitespot), how do i do it? what should the copper be, for how long? then how do i get the copper out of my water when ive finnshed?
- If this is your first time treating with copper, then I would recommend a chelated copper like Seachem's Cupramine. Chelated copper is buffered, which makes it easier to maintain at a safe level, but it can be less deadly to the parasite. Non-chelated copper, like Red Sea Copper, must be administered and monitored very closely, to prevent overdosing, but it is the most effective form of copper treatment. Either way, you will need to buy a copper test kit, to ensure that the copper is maintained at therapeutic levels (0.15ppm-0.20ppm or 0.15-0.20 mg/l). I would dose the copper as recommended by the manufacturer, and maintain therapeutic levels for a minimum of 14 days. I would also raise the temperature to 80 degrees, to speed up the parasite's life cycle. I would also recommend testing your copper level at least once daily, but 2-3 times per day would be better. After 14 days, I would begin to remove the copper with some activated carbon, or even better, an adsorbent like CupriSorb, if there are no more visible spots. I would also keep the fish in quarantine for at least 14 more days after treatment, to ensure that the fish has been completely rid of the parasite. The entire quarantine should last at least one month. Please see the links below for more information. Regards

- Q:Is the refrigerator copper tube good or aluminum tube good?
- For refrigerators, the use of copper tubes and refrigerators with aluminum tubes are good, and the difference between the two is not great.Aluminum or steel and copper has been used in the refrigerator for many years, has been known as a relatively mature technology, most refrigerator manufacturers are handy application, there are still some gaps only a few manufacturers application technology, does not have its own mature process, or use of brass.What material for piping, parts each part of the refrigerator, the refrigerator manufacturers at the beginning of the product design has been tested a lot of long time, will use in the determination of the material used in parts of no problem, not the temerity to replace material. If the refrigerator that use aluminum tube is not good, the refrigerator manufacturers should be more worry, more anxious than users, because it directly affects their profits, their reputation. After all, refrigerators are sold out and there are still years of warranty.When purchasing refrigerators, do not think too much about whether the refrigerator is made of copper tubes or aluminium tubes.
- Q:im trying to attach aluminum 1 inch fins to a copper pipe (radiator heater pipe). (dont ask). im trying to find the best glue to do that. i think i can use epoxy to do that.any other suggestions ?
- Copper and aluminum form a bond that when it gets wet will cause the aluminum to disintegrate. This is called electrolysis. If you have any choices, use copper fins, as a second choice aluminum pipe as an alternative. Aluminum has a very poor coefficient of heat. JB weld will work.
- Q:What is copper used for in technology? or what is it's uses in technology?
- copper is used most extensively for all the wireings in each and every electrical item u see all motors have copper its there in electromagnets u name it it has copper copper utensils are also used in many places it has like infinite uses
- Q:When I mixed Copper Sulfate and baking soda, I got a blue precipitate, I'm pretty sure this is Basic Copper II Carbonate. If I was to mix Sodium Carbonate instead of baking soda, would just Copper II Carbonate precipitate out instead? Also, does using baking soda to make a carbonate always make it a basic carbonate? Thank you for your time.
