Brass scrap is supplied for metal recycling and alloy production.
Brass scrap, commonly sourced from plumbing fixtures (faucets, valves), electrical components, and industrial manufacturing waste, is a valuable, recyclable, and copper-based alloy. It is broadly classified into yellow brass and red brass, often identified by color or a file test. Cleaning brass (removing iron/chrome) boosts its value.
Common Types and Sources
Yellow Brass: Plumbing fixtures, faucets, light fixtures, and hardware.
Red Brass: Valves, sprinklers, and pipes often found in HVAC and plumbing.
Industrial/Other: Bullet casings, keys, and industrial manufacturing turnings.
Scrap Identification and Processing
Cleaning: Remove chrome, paint, and iron contaminants (using a magnet) to ensure it is “clean” for higher prices.
Testing: Use a file to check for a yellow (yellow brass) or red/copper color (red brass) underneath the surface.
Processing: Before melting, large pieces are cut, and hollow pieces are flattened.
Recycling and Value
Valuation: Prices vary, with cleaner, sorted, and higher-copper content (red) brass fetching more value.
Recycling: Scrap yards (like SA Metal Group in South Africa) buy and process it by melting in furnaces, often with borax and glass to manage zinc loss.
Market: Global trading exists, with specialized suppliers available.
