  • PhosCopper 0
    (BCuP-2)
    Copper and phosphorous alloy offering excellent liquidity for tight fitting joints. Used extensively in the Heating, Ventilating and Air Conditioning (HVAC) industry to make preform rings for evaporators/condensers.

    PhosCopper 0LP   Flow is more sluggish than the PhosCopper 0. Fit-up should provide .003-.005" clearance.

    PhosCopper 0HP   For use with copper or brass. Fluid alloy, requires good fit-up, .002-.004" clearance.

    PhosCopper 2
    (BCuP-6)
    Combination of low silver with high phosphorous creates very good fluidity. While not quite as liquid as PhosCopper 0, tight fit-up is recommended.

    PhosCopper 2LP
      Sluggish flow, used for copper joints with wider clearances of .003-.006".

    PhosCopper 2HP   Used for copper or brass. More fluid than the PhosCopper 2LP. Clearances of .002-.005" recommended.

    PhosCopper 5
    (BCuP-3)
    Delivers moderate liquidity and improved gap filling compared to PhosCopper 0. The 5% silver content provides good economy when compared with PhosCopper 15.

    PhosCopper 5LP   Primarily used where fit-up can't be controlled, clearance .003-.006".

    PhosCopper 5HP
    (BCuP-7)
    Similar to PhosCopper 5. Developed especially for use as a preform alloy, the higher phosphorous content delivers good liquidity.

    PhosCopper 6   Medium range alloy for applications with clearances of .002-.005". Use with copper or brass.

    PhosCopper 6HP
    (BCuP-4)
    For copper or brass. Fluid alloy for controlled clearances of .001-.004". Good for automated brazing applications.

    PhosCopper 6D
    Premium alloy developed to mimic brazing performance of PhosCopper 15 at lower cost.

    PhosCopper 15
    (BCuP-5)
    (Formerly AB-15)
    This very popular alloy offers superior ductility and strength. It is suitable for wide gap applications. Joint clearances of .002-.006". Easy to use, good control. Used extensively in copper tube joining applications.
