You can convert soft-drawn copper to hard-drawn. Tie one end of the copper
wire to something secure. Get a good grip on the other end and just lean
most of your body weight against it (or use some other technique to apply
about 75-100 kg of force). The wire will stretch and harden. Once you've
done this, it won't stretch anymore.
