I stand by that.

I stand by that.

Physician, heal thyself!

A soft alloy with silver or copper can be more conductive
than pure aluminum.

Can you give an example of a AgCu alloy that (at room temperature) is
softer than the pure state of the dominant constituent?

Can you give an example of a AgCu alloy that is a better conductor than the
dominant constituent?

Hint: The semiconductor industry routinely adds a little bit of Cu to the
Al used for on-chip wiring. It is well known that this decreases the
conductivity. (They do it to improve the mechanical properties.)
