Copper Annealing

Copper Annealing. When copper is worked, meaning bending, folding, hammering, etc., the copper becomes more and more rigid. Continued work will cause the copper to fracture. To avoid this, it is time to anneal the copper.

That is an interesting idea! I've never tried that and thus don't have any experience to share with you. You may have hit on a whole new techniques. Be anxious to hear how it turns out.

ive heated copper at 265 degrees Celsius at different time intervals i found that after some time the hardness of copper decreases why is that

[897473]

@coma22309 if you work with copper, such as hammering or bending, copper becomes more rigid. If you heat copper it becomes softer, more malleable.

Either way you are changing the internal structure of the metal.

Look up Annealing (metallurgy) in wikipedia

I agree, copper is an amazing metal. Thanks for watching.

unlike ferrous metals, you can anneal copper by quenching as well as air cooling.

@RowanTaylor You're right. Many people do quench in water. I prefer air cooling but it's just a personal preference.

Thank you for this. Excellent explanation.

can i forge weld copper wire into a copper sheet buy weaving it the wire like thread into a sheet, heating it in a forge, and hammering it flat?

Excellent video - thanks!

wow... the coloration of the copper, the second time you heated it up.. real nice.. thnx for the upload :)

Wonderfully simple video, and that's exactly why it helped. =)
