Siding
Must be clean no glue on the back. trim coils, siding, down spouts, gutters, leaders, shutters.
Clean AL Wire
Same concept as a #1 bare bright only aluminum, clean stripped aluminum wire.
Thermo
Looks like a normal sheet / prepared aluminum the only difference is a rubber strip down the middle of the window frame. always keep these separate from your other aluminum.
Dirty AL
If the AL is dirty ex: heavy steel, rubber, fabric, screws it will be downgraded by percentage.
What is solid copper?
Solid Copper. Solid copper has two different grades. For copper #1, it can’t have any brass or large amounts of corrosion. This includes copper tubing and pipes if fittings are removed and they’re not corroded. Copper wire without any insulation and thicker than a pencil lead, about 12 gauge, are considered #1.

Copper wire 25% includes heavily insulated wire and is considered the lowest grade of copper. Copper wire 45% has thinner insulation, but the copper inside is still thinner than a pencil lead. Copper Wire 55% has thinner insulation and the copper wire itself is thicker than a pencil lead, typically around 12 gauge or lower.
