Hardness: Not rated Yield Strength: 15,000 to 25,000 psi Temper: 1/2 Hard (H02) Alloy 360 is known as free-machining brass. Its lead content prevents successful welding but does provide lubrication to enable high-speed machining such as drilling, milling, and tapping with reduced tool wear and breakage. Alloy 360 is corrosion resistant and has a smooth finish that readily accepts plating. Not heat treatable. Warning! Hardness and yield strength are not guaranteed and are intended only as a basis for comparison.
