Brass is a metallic alloy that is made of copper and zinc. The proportions of zinc and copper can vary to create different types of brass alloys with varying mechanical and electrical properties. Dezincified (DZR or DR) brasses, sometimes referred to as CR (corrosion resistant) brasses, are used in high corrosion environments and where normal brasses do not meet the standards. Applications with high water temperatures, chlorides or deviating water qualities (soft water) play a role. DZR-brass is excellent in water boiler systems. This brass alloy must be produced with great care, with special attention placed on a balanced composition and proper production temperatures and parameters to avoid long-term failures.


  • 330 Brass

    It is normally only available in tubing type products, and has a good balance of both workability and machinability . If you ever seen fire pole, you were most likely loooking at 330 Brass.

  • Minimum Properties

    Tensile Strength, psi 65,300
    Yield Strength, psi 50,000
    Elongation 32%
    Rockwell Hardness B70

  • Chemistry

    Copper (Cu) 65 - 68%
    Zinc (Zn) 33.5%
    Iron (Fe) 0.07% max
    Lead (Pb) 0.2 - 0.8%

  • 360 Brass

    Free Machining brass is the most commonly used brass. The presence of lead in the alloy creates a highly machinable material that can easily be cut and shaped.

  • Minimum Properties

    Tensile Strength, psi 58,000
    Yield Strength, psi 45,000
    Elongation 25%
    Rockwell Hardness B78

  • Chemistry

    Copper (Cu) 60 - 63%
    Zinc (Zn) 35.5%
    Iron (Fe) 0.35% min
    Lead (Pb) 2.5 - 3.7%

  • 464 Brass Naval Brass

    Used primarily in applications where corrosion resistance is important, the material has a small amount of tin added to help deal with corrosion, especially in seawater.

  • Minimum Properties

    Tensile Strength, psi 75,000
    Yield Strength, psi 52,900
    Elongation 20%
    Rockwell Hardness B82

  • Chemistry

    Copper (Cu) 59 - 62%
    Zinc (Zn) 39.25%
    Iron (Fe) 0.10% max
    Tin (Sn) 0.5 - 1.00%
