Old brass is a non-ferrous scrap metal that is commonly found in plumbing fixtures, hardware, and decorative items. It is a copper-zinc alloy that contains varying levels of other metals such as lead, aluminum, and manganese. Old brass scrap is valued for its corrosion resistance, durability, and malleability, which makes it a popular material for recycling and reuse in various industries such as construction, automotive, and manufacturing. The recycling of old brass not only conserves natural resources but also helps reduce waste in landfills and promotes sustainability.
