360 Brass, known for its strength and resistance to corrosion with properties closely resembling that of steel, is one of the most popular copper alloys used today. 360 Brass also known as Free Machining or Free Cutting brass, has the highest machinability of all copper alloys, and is the standard against which all the others are compared to. 360 Brass forms a thin protective “patina”, which, unlike steel and iron, will not rust when exposed to the atmosphere. As a high-density material, 360 Brass is ideal for heavy industrial parts and is valued for its high polished finish. 360 brass can be brazed and soldered, but is not heat treatable.
