Definition - What does Copper Cake mean?

This is a large slab of copper that is a byproduct of zinc production. The description of copper cake depends on:

  • Weight – weighs up to more than 3 tons
  • Dimensions (thickness, width and length)

It is used in this form to make alloys, rolling forms like sheets and batteries.

Corrosionpedia explains Copper Cake

The manufacture of metals usually ends in the form or shape required for easy transportation and use. These metal industries sell their materials in the following forms:

  • Sheets
  • Ingot
  • Billet
  • Pipe
  • Bar
  • Plates
  • Rods
  • Wires
  • Strips
  • Cakes, etc.

The copper cake is preferable in engineering and construction because of its high scrap value and excellent performance in terms of heat transfer. The resistance of copper to air and saltwater corrosion makes it durable. Copper alloys have reasonable strength and improved corrosion resistance. One common alloy is the copper cake obtained from zinc processing. The copper cake has reduced levels of oxidization, thus the upper surface retains a resistance to corrosion as compared to pure sheets.
