Sep 24 2021 2001. A. Aluminum will be very susceptible to galvanic corrosion in contact with copper assuming that the two metals are also in contact with a common electrolyte such as water with some ionic content. Almost any text or handbook on corrosion will have galvanic series table. The farther two metals or alloys are separated on the table faster the corrosion of

Aug 22 2020 The Siemens spec sheet says the max wire on the line side of the meter is 1 600kcmil OR 2 350kcmil for the two hots and 1 500kcmil OR 2 250kcmil on the neutral. In their meter requirements the power company says Lugs must accept 350 MCM aluminum wire. They say this is the largest wire they carry.
If a wire of smaller diameter with a higher gauge number carried that much current the wire could rise to a high temperature and cause a fire. Table of resistivities Calculate the rate at which internal energy is produced in 2.00 m of 12 gauge copper wire carrying a current of 20.0 A. W Repeat the calculation for a 12 gauge aluminum wire.
Use steel wool to clean the copper metal anode and the nickel plated steel or brass cathode. Attach bare copper wire to the cathode so that the object may be completely immersed in the plating solution. Determine the masses of the anode and the cathode with the attached copper wire . Make your mass measurements to the nearest 0.1 mg.
Mar 04 2011 Copper toxicity or poisoning is different from copper allergy. It is usually as a result of excess of copper built up in the body than its normal requirement. It can occur as a result of excess of copper in the food water and with nutritional deficiency of zinc manganese and other trace elements which are responsible for keeping copper
Dec 03 2013 In network communications bandwidth typically means data transfer rate i.e. the amount of data that can be transferred from one point to another in a given amount of time. 6 copper cables have a maximum bandwidth of 1 Gb/s while 5e copper cables top out at 100 /s. These bandwidths are sufficient for most industrial applications today.
and Copper II sulfate CuSO4 mixture. It will require separation by physical means. You will use the differences in water solubility to separate the two substances. Sand SiO 2 is insoluble in water whereas copper II sulfate is water soluble. When water is added to the mixture the sand will not dissolve but the copper II sulfate will.
Procedure. Weigh out 2 g 0.025 mol of copper II oxide and 1.6 g 0.025 mol of zinc powder. Mix thoroughly to give a uniformly grey powder. Pour the mixture in the shape of a ‘sausage’ about 5 cm long onto a clean tin lid sitting on top of a tripod or onto a strip of ceramic paper folded lengthwise into a V shape .
Copper sulfate is an inorganic compound that combines sulfur with copper. It can kill bacteria algae roots plants snails and fungi. The toxicity of copper sulfate depends on the copper content. Copper is an essential mineral. It can be found in the environment foods and water.

Feb 15 2017 BEWARE of wire sold on discount sites or any wire sold at too good to be true prices. Often this cheap wire is actually aluminum with a thin copper coating. Aluminum is only 60 as conductive as copper so you d have to use a much larger gauge to carry the same load.
Copper Wire Granulators for Sale Copper Wire Shredders Copper wire granulator systems granulate copper or coils and aluminum which allow you to maximize profits. The output of a copper cable shredder can range from 250 to 2600 lb./hr. These products allow owners to easily add value and upgrade material. Contact Online
There is a 6A cable distance limit based on how cables are designed and deployed. The longer the path that data has to travel the more susceptible it is to signal degradation. There are certain factors that can negatively impact data transmission along a cable impacting the 6A cable distance limit.
