How can I find out the weight of the copper content of various types of electrical cable per meter in g/kg's without having to strip and weigh varios AWG/mm2 lengths of cable or wire. I want to know so that I can quickly work out cash values of scrap cable.
About 60% of all copper and copper alloys consumed in the USA are used because of the electrical conductivity of the metal, and about 80% of that is wire and cable.
So we assume that 20% of the weight of copper wire is actually copper. Here is a table of the weights of AWG/mm2 legnth cable wire with weights of different sizes of cable wire.
If I need more information please let me know!! I am happy to help. If I have answered your questions, please accept and leave positive feedback so I can continue helping others. Thanks!
Relist: I still need help.
What I am looking for is table that tells me per meter (1000mm)length, of any given AWG/mm2 (US and UK sizes of cable core)the weight in Kilos of the copper core. I can see no firm evidence this answer that the core is approx 20% of the weight of any length of cable. I am hoping to have a point of reference whereby i am quickly able to calculate that the scrap value (for example) of 85 meters of 120mm2 4 core cable is £X based on the current market price of £Y per metric tonne :)
There is a list at http://mdmetric.com/tech/wirewt.htm which might be more helpful. It has weights per length for standard wire sizes.
Reply to Peter's Post: Hmm, this table doesn't really help me that much. It gives a weight but for what length and it isn't clear if the weight given is for a single core, multiple cores overall or the combined cores and insulation? There is also a bit of confusion in the cable sizes between US and UK standardisation (ie AWG/mm2)It's probably a very useful table for an electrical engineer or somebody with a bit of technical knowledge, but I'm afraid it's not as concise an answer as I was looking for. sorry:-)
Actually, you could make your own table: The density of copper is 8.96 gm/mm^3For any diameter of wire - the cross sectional area would be calculated by the formula for area of a circleradius=diameter/2Area = r^2 * pi To calculate volume you multiply by the lengthIf each unit was measured in mm (diameter and length) you would then get mm^3 as your volume. To get weight in grams - multiply by the density.You could develop a spreadsheet that would automatically do the calculation for you, including any conversion you wanted from feet/meters or pound/kg
I'm rubbish at calculations like this. I'd really like a table based on the following:
1 core, 2 core, 3 core, 4 core.
(mm^2) 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500.
kg per mtr, kg per ft.
If anyone can come up with an accurate table that would be worth $15.
If someone fancies writing software for a nice, tidy looking desktop application that I just enter 1.X no:core/s 2. X mm^2 3. X meter/ft
(and it would at the click of my mouse give me)
total= X kg copper content.
I'd happily pay an extra $30 for it! :-)
While I could develop such a table - the table that the other expert gave you really provides the information.The link to the information ishttp://www.interfacebus.com/Copper_Wire_AWG_SIze.htmlIn the details provided on this page this weight is WITHOUT insulationHere is another table which gives the weight of solid and strand type with weight per 1000 feethttp://www.engineersedge.com/copper_wire.htmhttp://www.nehringwire.com/html/p4.htmLet me know if these are what you are looking forFamilyPhysician39089.5500636574
not really i'm afraid.
OK...I'll work on that over the next day - It will take a day or so
Here is an Word document with the information in table format (done in Excel)If you print this and laminate it - you could carry it with you, and easily look up the weights IMPORTANT - The diameter is the diameter of EACH CORE - NOT the the total diameter of the bundle. In cases where the cores were not equal in diameter - you would add the diameter of each core from the 1 core columnFamilyPhysician39090.1264729514
Reply to FamilyPhysician's Post: Hi, WOW! I'm still a little confused. I'm assuming that the second column is the surface area of a core mm^2? if so what is the first column? Also if this is the case then I only have calculations upto 5mm^2 and I only have length in feet (Everything's done in meters in the UK)
In the one I gave you: The first column is diameter in 1/1000's of an inch (MILS), the second column is the diameter in MM.The 3,4,5 columns are the weight of 100 feet of single, double, and triple coreColums 6,7,8 are the weight of 100 feet single, double, triple core in KGI can convert this to kg per 100 meter if you would prefer, and only use the diameter in mm only. I can also extend the diameter to higher amounts if you want.Here it is in pdf formatThere was an error on the first one - this one has corrected that error. Sorry for the confusion.FamilyPhysician39090.9145930556

This is getting really close to what I'm looking for. Now if we're able to reduce this table down to the following, we're there!
all i need is a table with weight in kg for one meter length, for the following core surface areas (all mm^2)
0.5, 0.75, 1.0, 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800, 1000.
If I get this I will be very, very happy!
I'm improving my Macromedia flash skills and I've created a nice little calculator for you.You can see it here.
Hi Peter, please please don't think that I'm trying to be awkward-I'm honestly not. But I've just typed 1 core of 120mm^2 X 1 mtr into the calculator and it's saying it's 101.335kg? similarly 1 mtr of 6mm^2 single core is also not coming out as I'd expect.
If you can get this ironed out I'll happily pay you as I've promised. The CopperWeightCalc looks fantastic by the way. Keep up the good work!!
120 mm^2 has a diameter of about 6.2 mm. A diameter of 120 mm gives an area of about 45 238 mm^2.
I am using diameter (mm across the copper core) not area (mm^2) for the calculator. This is so you can use enter the values in directly from the measurements and don't need to calculate anything first. If you have a handheld computer (PocketPC for example) with Flash you could put the calculator on there and with a micrometer and tape measure, you would have a portable tool.
I could change the calculator to use area if you need that.
Hi again, yes please! mm^2 is the standard classification for cable in the UK (its usually printed on the side of the casing), so if you can change the calculator to cross surface area that would be perfect.
Off-line until tommorow now, but thanks for your efforts so far, much appreciated!
I think this is what you needClick here
Version 2 of the calculator has been uploaded to the same location.
While proofreading the link I gave you - I noticed that I had prepared the table correctly except I included 90 instead of 95 as your requested.Here is the table with the values your requestedPeter's calculator will give you the same values as well if you want to use the online calculator as well.Thank you for using JustAnswer.
