Notes:
The close tolerance manufacturing processes of extrusion, drawing,cold rolling, hot and cold stamping, and casting ensure that near-net component preforms are readily available.
Brasses particularly leaded brasses are capable of being machined at very high speeds and feeds with very little tool wear.
A premium price is paid for brass swarf or scrap (clippings from stampings, sprues from castings etc.).
In normal atmospheres plating and painting is not required to prevent corrosion. If however a more wear resistance or decorative finish is required such as chromium plating brass provides the ideal substrate. Most plated finishes are porous and the corrosion resistance of brass prevents the early onset of cracks, blisters, or eruptions of rust through the plating which can occur if steel is the substrate.
When brass is resmelted for recycling there is no loss of mechanical, electrical properties.
The infrastructure to collect and recycle brass has been in place for many years and is known to everyone and everyone is aware of the value of scrap brass. The majority of extruded brass is made from recycled material.
