Aluminum Hookup Wire - Page 2

If you want exotic wire, I get the bare Cardas silver from Michael Percy, and teflon sleeving to fit. Sounds good, solders well, costs.

The reviews on silver coated copper are variable. Apparently some is heavily coated, some barely coated; some apparently sounds vile, some very good. So I just avoid the whole thing, and use the solid silver.

You shouldn't be paying much more than the market price of silver (about $200/kg).

Why waste money on Cardas when you can buy soft tempered fine silver wire from a jeweler?

Do you cut the legs of electronics parts ultra-short so there is less signal path through copper? Did you wind your transformer with silver? Your mains cable? If you use PCBs instead of point to point, is it silver instead of copper PCB?

Copper clad Aluminium

Quote:

Copper clad aluminum is a composite wire consisting of an aluminum core clad with ETP copper. Even though the material is 90% aluminum, the wire has high frequency electrical properties equal to solid copper. MWS Wire Industries produces a broad line or round, flat, square, and rectangular copper clad aluminum wire. Copper clad bare, plated, and film insulated. Copper clad aluminum is widely used in applications requiring the conductivity of copper while retaining much of the weight advantages of aluminum.

D.C. conductivity....65% IACS
14 to 40 AWG

This only makes sense for high frequencies due to the skin effect. For audio frequencies, the aluminum core will be doing most of the conducting since it's the bulk of the cross-section.

Thank you very much James you made my day ! This is just what the doctor ordered...no aluminium oxide to worry about & there is 24 AWG

God bless you !!
