First up, there is one very important item you'll be needing.. a magnet! You can find magnets everywhere, there in speakers, microwaves, and in most electronics which you can pull it and use. You can easily identify the common metals just by their characteristics. Now, my guide on how to identify different metals.
Aluminum
- Very light
- Doesn't stick to a magnet
- Doesn't rust
- If chipped, leaves a saw edge
- Heavy
- Sticks to magnet
- Rusts
- Strong
- Common
- Yellow-ish if high in zinc, otherwise reddish
- Doesn't stick to magnet
- Doorknobs are usually brass/bronze
- Doesn't stick to magnet
- Reddish Brown
- Oxidizes into green
- Found in wires and electronics
- Copper #1 = Clean Copper
- Copper #2 = Painted Copper
- Light Copper or Copper #3 = Copper Sheeting
- VERY HEAVY, two tablespoons can weigh over a pound
- Expensive! A pound goes for about 7$
- Super strong
- Makes short, dim, dark red sparks
- Usually found in end mills, saw tips, and tool inserts.
- Very Malleable and Soft
- Very Toxic
- Heavy about 150% denser than iron
- Non-Magnetic
My biggest problem is distinguishing the difference between brass and bronze
