•  Strong & Ridged

•  Durable & Rust Resistant

•  Gray Appearance

•  Galvanized or Unfinished

Aluminum

•  Light! Great Strength-To-Weight Ratio

•  Easily Formed

•  Silver Appearance

Brass

•  Heavier Than Steel

•  Stiffer Than Aluminum, But Still Formable

•  Gold Like Appearance (when polished)

Galvanized wire has a zinc coating for increased corrosion resistance and is great for soldering. Can be brazed. Use with electrical / plumbing solder. Use unfinished wire for welding.

Lightweight, corrosion resistant to most chemicals, easy to machine, and a good conductor of heat and electricity. Use with aluminum solder.

Consists primarily of copper but can contain as much as 40% zinc, which increases machinability. Doesn't spark with a grinder. Good conductor of heat and electricity. Often used for nuts, rivets, hinges, locks. Can be brazed. Use with electrical / plumbing solder.
