Sequoia Brass & Copper has over 40 years of experience supplying nonferrous metals like brass and copper to fabrication centers across the US. We carry an extensive inventory of brass products, including 330 brass. Also known as alloy C33000, this low-lead metal responds well to machining, forming, and cold-working. Due to its many desirable properties, 330 brass is well-suited to various applications, including consumer and commercial tubing.

330 Brass Material Properties

330 brass is an easily machinable material that requires minimal finishing or corrections. While its lead content makes the material more workable, it makes welding difficult. 330 brass is composed of between 65-68% copper, 0.2-0.7% lead, 0.07% iron, and zinc as the remaining portion. Some of its most notable characteristics include:

  • Corrosion Resistance. 330 brass will not rust or corrode when exposed to freshwater or saltwater. This makes it a great option for tubing and outdoor applications.
  • Machinability. 330 brass has a machinability rating of 60. This means that it is easy to cut and fabricate into complex, precise designs. The cut lines take on an acceptable surface finish that often does not require further processing.
  • Workability. 330 brass can easily be formed into new shapes without compromising its structural integrity. In addition to its workability, 330 brass offers good resistance to cracking and fracturing.
  • Solderability. 330 brass is suitable for soldering processes. As long the material’s oxidation rate and high conductivity are accounted for, technicians can easily solder joints to brass tubing.
  • Finishing Characteristics. 330 brass features a nice surface finish after cutting and machining, requiring minimal finishing processes to produce the completed product. This material is easily polished and typically does not require deburring.
  • Brazing Characteristics. 330 brass is highly suitable for brazing processes to join metal pieces together.

Physical Properties of 330 Brass

Identifying the best material for any application requires insight into its physical properties. Some of the most important properties of 330 brass include:

  • Density: 0.307 lb/in3 at 68° F
  • Electrical Conductivity: 26% IACS at 68° F
  • Elongation at Break Percentage: 32%
  • Hardness Rockwell/Brinell: B80/147
  • Shear Strength: 43.5 KSI
  • Shear Modulus: 5,660 KSI
  • Modulus of Elasticity: 15,200 KSI
  • Melting Point: 1660° F solid and 1720° F liquid
  • Poisson’s Ratio: 0.35
  • Specific Heat Capacity: 0.09 Btu/lb/°F at 68° F
  • Thermal Conductivity: 67 Btu/sq ft/ft hr/°F at 68° F
  • Ultimate Tensile Strength: 65.3 KSI
  • Yield Tensile Strength: 50 KSI

Advantages of 330 Brass

330 brass is the ideal choice for many plumbing and manufacturing projects due to its many desirable properties compared to other metals. It is easy to machine without extensive finishing or corrections, making it a cost-effective option that streamlines manufacturing operations. Due to its lead content, 330 brass is easy to work with but isn’t the best option for welding or highly corrosive environments.

It is commonly chosen for tubing; however, it’s important to understand the fluids that will be running through them to ensure 330 brass is compatible with the environment. It offers great cold workability and machinability and can be formed using bending, shaping, machining, piercing, and punching processes.
