How to Melt Copper Wire

Save

Copper is the third most utilized metal in the U.S. behind iron and aluminum thanks to its malleability, ductility, conductivity and resistance to erosion. This semi-precious element boasts hundreds of applications, from electronics to transportation to health care products, and is often combined with other metals to form alloys. Those who wish to refashion copper wire for some other use often start by melting it down, although such a dangerous procedure should only be undertaken by knowledgeable individuals.

Things You'll Need

  • Propane torch
  • Propane gas tank
  • Copper wire
  • Tin snips
  • Crucible
  • Crucible stand
  • Thick oven gloves
  • Welder's face shield
  • Crucible tongs
  • Workbench
  • Flat iron pan
  • Metal casting mold

Preparation

  • Connect the propane tank to the propane torch. Turn on the propane tank and test the torch to ensure it is working properly.

  • Cut the copper wire with tin snips and place them inside the crucible.

  • Place the crucible into the crucible stand and position the propane torch directly underneath the crucible.

  • Put on the oven gloves and face shield.

  • Adjust the propane torch to a low heat setting and turn it on. Preheat the copper at about 212 degrees Fahrenheit to remove moisture.

Melting and Pouring

  • Turn up the propane torch to its highest setting. Copper melts at approximately 1,981 degrees Fahrenheit and will emit green flames as the melting process begins. Maintain this temperature until all the copper has melted.

  • Place your metal casting mold on a flat iron pan to catch any spilled metal from running onto your workbench.

  • Lift the crucible out of the crucible stand with a pair of crucible tongs and gently pour the molten metal into your metal casting mold.
