Copper For Aluminum?

"Sounds Sweet brand sugar"

In your ears? Come on now...You put a cup on top of each speaker, or pour it in your speaker cabinet to tune the enclosure. Be carful, some have reported that the "sugar highs" are on the bright side and can be fatiguing...

So I wasn't done,

If you use it to fill your bass traps it'll make any sub sound "sweet".

I defy you...

Actually it's not uncommon to find aluminum clad wires in industrial electrical gear. It's not just tinned ends. Strip it back and the whole length is alluminu clad. It's easy to identify. When you cut the wire tip with dikes you'll notice the end is copper.

...to point me to a reference (ANY ref) for aluminum-clad copper wiring...you will find Ni-clad Cu, Sn-clad Cu, Pb-clad Cu or CCA, Cu-clad aluminum...In fact, if you do a search on MSN.com for "aluminum clad copper wiring" there are zero, none, nada results returned. Do a Google, and you get results for copper-clad aluminum and various permutations of those words, but none the other way 'round.

And FWIW, when I say "tinned", I don't mean use-specific tinning of the ends after the fact, but refer to copper-core wiring which is clad with any of the previously mentioned metals that will aid in soldering as a part of the manufacturing process over it's entire length. Just try soldering aluminum with a simple Weller and some 60/40.

So, you can cut it with dikes or shears or reveal it's copper core with abrasives, but the shiny outer cladding ain't aluminum; many people make that mistake.

HHmmm...

First thing you do is want to go on the attack.

You consider that an attack??? Facts=attack...interesting. Speaks volumes.

Hey, if you don't believe me that alluminum is a common material to coat wires, just ask any lineman from your local electric company. In their case most of the high voltage (over 13KV) is alluminum coated steel. But that due to the strength of steel.

I'm sorry...it was speaker/electronics wire we were speaking of and not high tension transmission line wasn't it? Where exactly does Al-clad steel come in? Did I miss something? Was I out sick that day?

Solid alluminum wire also was very common in house wiring before code changes.

Yes, it caused fires as I recall or was at least suspect in that regard. It is generally recommended that it be replaced when practicable.

Now about the only place solid alluminum wire is used in the house is the drop and the main.

Yes, as an economy and for a more favorable length/weight ratio...and as a drop, it has more air to better cool it. See fire hazard reference above.

There are also many alloys of alluminum, nickel and other non-corrosive metals. The real point is that the entire length of the wire or cable is coated with an alloy that's silver in color. It's not just a "tinned" end.

Let me refresh your memory with a quote which you saw fit to quote, but obviously didn't quite get:

And FWIW, when I say "tinned", I don't mean use-specific tinning of the ends after the fact, but refer to copper-core wiring which is clad with any of the previously mentioned metals that will aid in soldering as a part of the manufacturing process over it's entire length. Just try soldering aluminum with a simple Weller and some 60/40.

And yes, there are a myriad of bimetallic combinations available for specific uses...unfortunately Al-clad Cu ain't one of 'em.

I think you need to switch to decaf

While I do enjoy a cup now and again, I don't drink coffee on a regular basis...

I've heard living in Fla. tends to thin the blood...
