About brass scrap
The cleanest brass grade is yellow brass solids: taps, valves, fittings, locks, handles and vessels with no steel, plating or plastic. Chrome-plated bathroom fittings still count as brass but are graded slightly lower, because the plating has to be dealt with in the melt.
Machining shops produce honey brass turnings — bright golden swarf from turning brass rod. Kept clean and drained, this is a well-paying grade; mixed with steel swarf or soaked in coolant it drops sharply, so a dedicated bin is worth the floor space.
Watch for pieces that look like brass but are not: gunmetal and bronze are heavier and redder, while plated zinc castings feel light and are worth far less. We identify these at intake and grade each portion rather than paying a single blended rate.
