Brass tubing is an alloy of copper and zinc and typically contains 65-70% copper, 30-35% zinc, and sometimes small amounts of lead, iron or manganese. Brass tubing has excellent mechanical strength, making it a popular choice in the construction of piping systems. It also is highly resistant to corrosion, which is why most brass plumbing fixtures have a long lifespan. Brass alloys come in various grades, which depend on the amount of zinc and copper. The mechanical and electrical properties of brass are altered with varying amounts of zinc and copper. The gold-like appearance of the polished brass tube makes it a choice of decoration. The machinability of brass is increased through the addition of Lead.
Due to its malleable nature and affordability, the brass tube has become extremely popular. Brass round tubing offers excellent corrosion resistance and superb electrical conductivity properties – qualities which make it ideal for producing amps and musical instruments.
Locks, gears, door knobs, ammunition casings, valves and bearings are some low-friction applications that use brass. The malleability in thin brass tubing is higher in comparison to bronze and zinc. The melting point of brass is relatively low. In applications where sparking is dangerous, use brass to prevent any hazardous outcomes. High workability and durability demanding applications make use of brass. DZR (Dezincification Resistant) is the corrosion-resistant form of brass, which is used specifically in applications requiring high corrosion resistance. The durability of DZR brass also makes it usable in water boiler systems. Bio-fouling is prevented in brass.
