Alex Zandonella Posted September 24, 2022 Share Posted September 24, 2022 Hello everyone! In a few weeks my girlfriend has her birthday and as a present I wanted to make her a bracelet made out of bronze so I went to my steel supplier and got a round bronze rod (25mm). Today I wanted to try forging it, after a few attempts it just kept cracking and breaking it apart. I looked up what might be causing it. Apparently it should be how the allow is made up. If there's to much zink and lead it makes it brittle. My Bronze is called here in Italy RG7 and the datasheet says about a 1,5 to 11% tin and 1 to 9% zink and some traces of nickel and lead. So technically it should work for forging. The right temperature should be on a dull orange. I tried it a few times with no success. I tried forging it cold, it worked a little better but still opened little cracks. I tried heating it up more but obviously it just started melting on the outside. Some even say that you should hit it gentle so after failing with my 4 pound hammer I tried it with my 2 pound hammer, no difference really... So I'm a bit frustrated now, not knowing what I really do wrong. Attached you can see some pieces that broke of. My guess might still be that the bronze is not suitable for forging, but as I'm not sure I wanted to ask you guys for your opinion. If it all doesn't work I might switch to copper even though I preferred bronze for the bracelet. Greetings Alex Link to comment Share on other sites More sharing options...
