Copper-clad Aluminum Wire chemical formula and processing needed [Indonesia] 

November 16, 2006

Good day,

I'm a graduate fresh from uni. Me and a good friend of mine are being assigned by a company we worked for to find information regarding Copper-Clad Alumunium Wire. Now, as much as we would like to impress our boss, the information regarding the process of making one is not as easy as it seems. We may be 'green' in this subject, but we are certainly not 'yellow'!

So if anyone out there please please can help me out a little bit, it would be much appreciated !

My boss would like to know the information are:

1. How large should the tank be

2. What and how much chemicals for the Cathode

3. What and how much chemicals for the Anode

4. Approximately running speed of the machine when coating

5. The Ampere and voltage required

6. Diametre of the wire 0.5mm can be drawn to 0.12mm

Much gracias to people out there trying to help ~!

Impress your boss by locating the right consultant, or at least an experienced plating process vendor, Andrew. There is far more than one tank ("the tank"), probably more like a dozen. This is a major industrial installation rather than a cut & try one-off tank. You'll probably need steps for cleaning, acid activation, zincate, zincate stripping, rezincating, cyanide copper plating, and acid copper plating, with rinses in between. An alternative is a stannate process in lieu of the zincate. Good luck.

Why are you plating? Worked for Texas Instruments in Wire Div. for 35 years and CommScope Wire for 5 Years before retiring. You should look at other alternitives.
