Anyone heard of "Gold Plus"?
Ran across an alloy being sold in Thailand under various trade names.
It was a very basic aluminium bronze with a composition of about 94%
Cu, 5% Al, 1% Si. It's very drossy to cast and has a gold color that
resists tarnish. It does get a bit dull looking over time. It has
been called "V - Gold", "China Gold" also. It will gunk up your
crucible & stirring rods with dross from the aluminum oxide, flux
