copper vs aluminum for terminals/blocks
ncc74656 replied to ncc74656's topic in Amplifiers / Head Units / Processors / Electrical
can copper be stacked? lets say i want to build for a max current of 500A. i can pretty easily get .25" copper but not any thicker. so if i had .25x1.25" that could carry around 300A. could i take two .25x1.25 and stack them to get 600A of current? and if so do i just bolt them together or solder or braise? in an ideal world id like to have a .75" thick copper bar to drill and tap holes into for bolting ring terminals to. as for contact area - i cant seem to find any good data on contact patches. it does not make much sense to me that you have a thick bar with say 1/0 cable coming in and then a ring terminal with about 1/8 square inches of contact surface area on the ring terminals... i dont have any of this installed yet so i cant do a voltage drop test. i want to get things right before i install (or as close as possible). i built some aluminum battery terminals yesterday that seem to be working very well. i am picking up some of that paste that prevents corrosion. im concerned by the shrinkage of aluminum compared to copper so i guess ill find out if my bolts come loose in a couple weeks... i wish i could find a 1X4X15" brick of copper, that would be perfect for what im doing. its just so much easier to find aluminum in those sizes and WAY cheaper. you mention copper can be much thinner - from what i have read and was told by people in the AC electrition field (no idea how DC changes things) aluminum must be upsized by about 25% to carry the same current as copper, the load isnt the major issue in their field but rather the terminal connection and how much more aluminum expands and shrinks by temperature. i think thats right? -

Personally, I will avoid aluminum at all costs. It corrodes much quicker from electrolysis and galvanic corrosion. It's just not worth the trouble in an automotive environment. -

You can do that, but the point of contact is yet another point of resistance. With that being said, you generally need 3 times the surface area of aluminum to copper. In other words. all things other than thickness equal, a 1/4" copper bar will carry the same current (safely) as a 3/4" aluminum bar. - Yesterday

Definitely if your electrical box is in the basement submerged as well.. "Heated indoor pool"

yup. when running copper tho its hard to source pieces that are thick, easy to tap or thread. could you stack slices, say a few layers of 1/4" plate and add that up to a 3/4 or so thick bar? braise them together or solder? aluminum is much easier to find in blocks so thats why i was looking at using it. -
Indoor pool? High-class living right there.

Pray it doesn't warm up that fast here. My basement would be a swimming pool with the 3 foot mounds piled up....... and I'm watching it sprinkle down right now out the doors at work.

Copper is a better conductor so less material is needed versus aluminum in regards to resistance. -
11-year-old thread. Lol!

Well it all melted as its 45 degrees today.

What about 2 dp 15 d1 -
Yeah I bought the 65” Vizio at Best Buy. I wanted the tcl 6 series instead of 5. So I just bought the vizio. It’s a good looking tv the FALD is a bit strange on it. Only while playing video games. On amazon prime with 4K movies it looks amazing.

The Vizio E series was right there too. I've been looking on rtings.com a lot and they rated the Vizio E series a "better" TV than the TCL S515 overall, but the S515 was slightly better in the TV and Movie categories specifically, none of the others categories (gaming, PC, etc) matter to me in the least. And the TCL is like $40 cheaper.

copper can handle more current but if you up size the aluminum its just as good, right? say you need a grounding block or a bus bar - the copper bar is quite a bit more money but its smaller, if you dont care about size an aluminum bar that is 30% or so larger can handle the same current; is there any reason to go copper over aluminum? - Last week

So I bought a Visio e series. Good looking tv. The tcl is great tv as well. Go check out rtings.com. Great tv review website.
