Copper For Aluminum?

[jdh]

Hello Everyone,

I'm rebuilding the speaker output terminals on a vintage receiver.

All the internal wires that run to the terminals are made of stranded aluminum.

Q:

Anyone see a problem with extending these wires by soldering on stranded copper wiring?

Thanking all in advance,

JDH

No, and if you can, make them all copper. That will reduce the output impedance.

mixing aluminum and copper is not the best of ideas, as there are corrosion issues when these 2 metals touch. Soldering on aluminum is also dificult to say the least. There are some ways to do it but getting a good solder joint can be a problem. My recomendations would be to either stay with all aluminum or replace with all copper ( I don't know if this is feasible because I don't know exactly what you are working with)

Why do you think it is aluminum? I seriously doubt they used aluminum wires inside, even back then.

Thanks for the replies, Gang,

Two clerks at the local electronics shop IDed the wire as aluminum.

After thinking about it, I too had my doubts so I hunted down the shop's owner.

Ends-up the wire is coated copper.

That is what I was going to say but better you found out independently

I never heard of aluminum being used in audio. Power lines, home cables of large diameters, yes, in audio, I will be shocked.

Copper is less expensive that aluminum, has higher conductivity and is readily available in wire form. There's NO WAY a company would ever use aluminum wire, but you already found that out...

You can buy magic aluminum cables though. Check out the prices on this stuff...and it's aluminum alloy.

I didn't see any pricing listed, but I wasn't looking too close. I didn't see anything there that made me think they had come up with something useful either

Here's the price listing:

Gotta love the price on the "Aluminata" stuff.

And people buy it They must, or it would not be on the list for sale.

I need to invent a $10/lb of sugar

I am working on $10/lb sugar, would be more for audiophiles though

Do you stick it in your ears? You'll have to come up with a cool name though...

Sounds "Sweet" Sorry I couldn't resist.

Would this be ultra pure cane or super sappy sweet brown. Oh, I'm sorry that is surely a secret at this point...

Hey i have an idea...if you cut it with crack your customers would do anything to get more!!!

Okay I'm done now,

"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,

"Alumi-sugar" aka Alumisuga If you fill your speakers, you'll need to replace it about once a month, so that mrtycraft stays in business.

Ants will take care of that!

 

[j_garcia]

I guess Mrty will just have to make it ant proof Or not, since that means more sales... Hey, can you recycle that stuff?

I wouldn't put...

...too much faith in these guys...first they say the wire is aluminum...then the shops' owner refers to it a coated copper? Do I have that right?

The term is tinned...copper can be difficult to solder properly unless it is tinned...
