Guides
Wire is where most scrappers make their copper money — and where the most value gets left on the table. Learn to identify every common cable type, what percentage of copper is inside, and when to strip versus sell as-is. Every guide here pairs with the Wire Yield calculator.
How much copper is actually inside each kind of cable — a sourced, conservative table you can trust, plus a calculator to run your own weights and prices against it.
Not all wire is created equal. Learn to identify every common cable on sight — from fat THHN to hair-thin Christmas lights — and know its copper value before you weigh it.
Run the numbers before you pay — weight, composition, asking price.
