What ever the chart says, mate, we know zinc is in short supply and is an irreplaceable industrial metal.

The beauty of zinc as a protective coating for steel is that if the coating is scratched, an electrolytic cell is set up which saves the steel at the expense of the zinc. Same scratch in a painted coating, even electrocoat or powder coat and the steel rusts under the paint which will peel off.

Also zinc is a battery metal, group it with cobalt, lithium and nickel. And everyone knows the world runs on batteries, even under the sheets.
