Al ,I need know how can cast of chrome in molten copper that has

Please if you any one can help me to achieved these requirements.

alloy with the ratios above Thank with my regards

Most of your questions I can't help you with, but the fact that you
don't
know if chromium is soluble in copper tells me that you haven't done
your
homework.

A Really Short Web Search tells me that chromium-copper systems are
pretty complex: apparently chromium isn't miscible in copper, so you
have
to work hard to get a nicely distributed suspension. This is NOT a
question that you're likely to get answered on an amateur
metalworking
group (although there may be some enthusiast or retired metallurgist
who
knows, in which case I'll be interested in seeing the answer
myself).

I think you have some research papers to seek out and read.

It shows how the solubility of chromium in molten copper increases
with temperature.
