Specific gravity 8.5, Moh hardness 3.5.  Normal 'Admiralty' brass 62% copper 38% zinc.  Often produced from machine shop swarf.  Degreased by heating or chemically.  Below 4% cosmetic only.  Above 4% by weight in a formula controls fade - due to formation of copper oxide which keeps the friction level up.  Tendency to polish.

Many companies also use brass chippings to help differentiate between friction material grades.  Products with higher brass content usually designates premium material.
