Combining copper with aluminum can drive up the conductivity, e.g. by cladding. What percent copper is allowed before it gets judged against the copper metric?

We have not yet developed percentage bins for amount of copper and silver. We simply provided a notion of what we might consider to be a breakthrough for 95% Cu or 95% Al.
