Hello, I have 12000 meters of 4mm diameter copper wire. It is pure 99,9% copper. Unfortunately it is too soft for what i want to use it for. How can i harden it ? I have seen many ways on the web but none is adapted to such a large quantity. Please help. Thank you

Hello. I'm interested in historical metallurgy, and I have a question about differing types of bronzes, specifically copper/tin and copper/arsenic. I cannot seem to find any information about producing harder flavors of bronze (preferably without resorting to zinc/brass). Anyone know specific copper/tin or copper/arsenic alloys that could be used to make tools to work cast bronze (90/10 or 88/12)? -Jeff

I have been using these two following steels for making damascus billets: UHB20C steel with the following properties: UHB15LM steel with the following properties: Now - I am wondering - does anyone here have experience with these steels? I tried hardening a blade in room temperature water, (single bar 100+ layers twisted 15 and 20 steel with a 1,25% C steel as edge steel in a san-mai lamination) but it cracked open at the edge as the lamination came undone in an area approx 1cm long. I then hardened another blade in vegetable oil (dual bar twisted, san-mai lamination) a

Hey Y'all I had a thought; does quenching a piece in oil prevent as much firescale, or is all the scale formed in the forge, not the quench? Also, does heating a piece in a clay sleeve prevent scale from forming? Thanks and Cheers!
