Copper Vs Iron Whats The Difference Ask Difference

Apr 25, 2018 Iron metal has been used since ancient times, although copper alloys, which have lower melting temperatures, were used even earlier in human history. Pure iron is relatively soft, but is unobtainable by smelting because it is significantly hardened and strengthened by impurities, in particular carbon, from the smelting process.Apr 25, 2018 Iron metal has been used since ancient times, although copper alloys, which have lower melting temperatures, were used even earlier in human history.
