Offered in the 260, 270, 272, and 330 alloys, Brass seamless tubes are frequently used in outdoor and indoor design elements. Alloys are not differentiated and are dependent on availability. Identified by its characteristic dark-gold color, brass is a metal alloy consisting of copper and zinc. In addition to its decorative appearance, brass offers other benefits worth noting. It has a higher malleability than both bronze and zinc, and is a good conductor of heat. Brass resists corrosion, including galvanic corrosion from saltwater. It is not ferromagnetic, which makes it easier to separate from other metals for recycling.
