Brass Extrusion and Components
Lead-free brass is a copper-zinc alloy designed to eliminate or minimise lead content (typically less than 0.25% by weight) while maintaining the desirable properties of traditional brass alloys. These alloys use alternative elements such as bismuth, silicon, phosphorus, tin, or nickel to replace lead while preserving machinability, strength, and corrosion resistance. Lead-free brass was developed primarily for safety and environmental compliance, particularly for drinking water applications, as lead can pose serious health risks when it leaches into potable water systems. These alloys demonstrate excellent corrosion resistance, good mechanical properties, antimicrobial characteristics, and comply with strict health and safety regulations, including the Safe Drinking Water Act, RoHS, and California Proposition 65.
