Cardas Cold Forging

Ultrasonic welding.

The linked article deals with mainly mechanical properties, but you get the idea.

Thanks, will read, but those pesky formulas:)

All said, $400 for retermination is definitely not VFM. Whether it is robbery or not cannot be confirmed without listening though.

One thing I haven't seen addressed either in the Cardas video or in this thread is that Cardas wire is coated - from their website:

As each strand is drawn, the resultant ultra pure surface is immediately given a urethane enamel "Litz" coating. This is a continuous process that results in a perfectly insulated strand and ultimate longevity of the conductors. Ordinary uncoated copper stranding corrodes in a relatively short time. Cardas meticulously maintains the purity of the conductor strands until they are sealed at termination.

In their previous soldering process it is my understanding the wire was "tinned" in a solder pot to remove the enamel coating. In the ultrasonic welding link posted above, enamel coatings are removed by "high frequency vibration." How is the enamel removed in the Cardas "Cold Forging" process, or is it simply mashed into the connection?

Lenny, I'll give my opinion freely without question. Thanks.

The fact that I have not heard them does not mean anything. But one thing can be true, fusing different metals can easily change the electrical properties in a negative way. So there may be some truth to the improvement by making the connection as solid as possible without actually binding the material.

And it all goes back to YOUR ears. Why do I even bother commenting on a subjective subject anyway? ;)
