Brass Round Bar 314, also known as leaded commercial bronze, is a free machining brass that offers superior thermal/electrical conductivity, good strength, and corrosion resistance. The lower zinc content of 314 gives it a reddish color along with superior resistance to cracking when compared to other alloys of brass as well. It is typically used in hardware, electrical components, fasteners, screws, and other industrial applications.
