Brass
An alloy that is 70% copper,30% zinc. One of the most widely used of the copper zinc alloys; malleable and ductile; excellent cold working but poor hot working and machining properties; excellent for soft soldering; good for silver alloy brazing or oxyacetylene welding, but fair for resistance or carbon arc welding. Used for drawn cartridges, tubes, eyelets machine items and snap fasteners.
