- When pulling apart transformers there are normally both aluminium and copper windings. You can tell the difference by the weight or by using a file to scratch the lacquer coating. If it’s alloy then it will be silver grey and if copper it will be a reddish colour.
- Most plumbing removed from houses and buildings can easily be separated into different grades of copper and brass using a grinder. Normally Copper No2 will only be the Copper joins or painted sections of pipe.
