Overview

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