Re: Working with cheap wire

Before you use copper wire, you can harden it.

To harden copper wire, clamp one end of the wire in a vice. Holde the other end with a flat nose pliers and stretch the wire so far as possible. You can stretch a 1 meter wire to about 1,20 m or more, before it breaks. Copper can not be hardened by heat treating.

I forgot! If you heat up the wire to about 600 degree Celsius or more after the stretching, the wire gets soft again.

But that is not a copper alloy but a 750 gold alloy. And the price is many, many times higher.

Pure copper can be hardened only by cold working. Flame hardening is not possible.
However, there are hardenable copper alloys. Search in the Internet for a suitable alloy .

You can also the following do. Clamp one end of the wire in a vice. Take the other end in a pliers. Straighten the wire as much as possible. By that the wire get harder. Bending the Omega after that

Looking for a way to harden copper

Julian*** — Mon, 02 Nov 2009 00:08:02 GMT

I am looking for a way to harden copper outside of work hardening. I have made an omega out of copper wire and I don't want to hammer it. I have tried tumble polishing it but it is still very soft. Is there a way to flame harden copper or bake it like Argentium?

Soldering Larger Brass Jewelry

kaysjewels — Thu, 29 Oct 2009 05:55:03 GMT

I have larger pieces (approx 40mm round, some larger) of 24 gauge brass sheet that I have tried numerous times to solder a brass bezel on with no luck, using past solder. I tried brass paste solder (grainier than silver paste) from Rio and easy silver paste- neither work-just doesn't flow or I have over heated it to a cement! Would additional flux help while using paste or would chip solder work better on larger pieces? I don't care if I use silver or brass solder. The paste worked fine on the bezel, but I can't seem to join it to the larger back plate. Knowing my problem is joining two metals of different thickness and size, I hope someone with more experience can help. Practice, practice, practice? Yes, clean, slowly heated the back plate... maybe not hot enough? Is the size the real issue? My torch- larger than Micro torch- still butane but can get a nice soft flame. Time to invest in Little Smith? I would love to finish my pieces! Thanks... anyone's opinion would greatly be appreciated! Kat

Supply Sources for SS necklaces,etc

Stlmag — Thu, 29 Oct 2009 01:54:32 GMT

Hello-

New here. I am spending too much time scanning the interent for sterling silver necklaces and SS discs for hand stamping, stamps for jewelry stamping (different fonts) I seem to be chasing my tail and getting nowhere. I have ordered from a few companies (one necklace source has poor quality necklaces and another never bothered to notify me they were out of discs) but I would like to find one or two to use all the time. Any advice for me?

Thanks
