    COPPER TEC 0% SILVER – ROUND (BCuP-2) 2.00mm

    Code: B000025
    AWS Classification – BCuP-2
    A self fluxing, low cost copper rod containing 0% silver suitable for copper to copper or brass joints where good fit up exists. Primarily for use on copper, this alloy may also be used on other non ferrous copper based alloys. Used mainly in the refrigeration & air conditioning industry as well as electrical conductors and brass pipe fittings. Due to its phosphorous content, the rod is self fluxing on copper to copper only applications.
    This rod can be used for joining brass and bronze, however Bronze brazing flux would be required for this process.
    Melting Point: 710 Deg C
    Flowing Point: 790 Deg C
    TIP: Surface cleaning of welding area is critical for capillary action to take place and form a solid bond.

    COPPER TEC 15% SILVER – SILFOS 15 (BCuP-5) 2.00mm

    Code: B000031
    AWS Classification – BCuP-5
    A self fluxing, copper rod containing 15% silver suitable for copper to copper or brass joints where close fit up does not exist. The addition of Ag assists in a lower melting temperature as well as the flow of the filler material. Often referred to in the industry as Silfos 15, the key element again is the inclusion of phosphorous. Although it increases the ductility of the filler material, it decreases the flowability of the rod, therefor the 15% Ag added assists in the flow of the filler wire.
    This product is used extensively in the refrigeration. Air conditioning, electrical conductor industry where agitation, vibration and extensive movement of the joints would be subjected to. A flux should be used when using this rod to braze brass or bronze.
    Melting Point: 645Deg C
    Flowing Point: 800 Deg C
    TIP: Surface cleaning of welding area is critical for capillary action to take place and form a solid bond.

    COPPER TEC 2% SILVER – SILFOS 2 (BCuP-6) 2.00mm

    Code: B000027
    AWS Classification – BCuP-6
    A self fluxing, copper rod containing 2% silver suitable for copper to copper or brass joints where good fit up exists. The addition of Ag assists in a lower melting temperature as well as the flow of the filler material. Often referred to in the industry as Silbralloy or Silfos 2, the key element again is the inclusion of phosphorous. Although it increases the ductility of the filler material, it decreases the flowability of the rod, therefor the 2% Ag added assists in the flow of the filler wire.
    The optimal fill gap is a maximum of 0.2mm, the filler metal cannot be used to braze iron containing materials such as carbon, stainless steel or nickel as the phosphorous in the rod will make the joint brittle (6% Phosphorous)
    This rod is used in the refrigeration, air conditioning, electrical engineering industries like the brazing of motor rotor bars to end rings.
    Melting Point: 650 Deg C
    Flowing Point: 740 Deg C
    TIP: Surface cleaning of welding area is critical for capillary action to take place and form a solid bond.

    Code: B000029
    AWS Classification – BCuP-3
    A self fluxing, copper rod containing 5% silver suitable for copper to copper or brass joints where close fit up does not exist. The addition of Ag assists in a lower melting temperature as well as the flow of the filler material. Often referred to in the industry as Silfos 5, the key element again is the inclusion of phosphorous. Although it increases the ductility of the filler material, it decreases the flowability of the rod, therefor the 5% Ag added assists in the flow of the filler wire.
    This product is used extensively in the refrigeration. Air conditioning, electrical conductor industry where the gap in isn’t a tight fit. It has a good electrical conductivity and a very high tensile strength of around 250N/mm2. Most commonly used in the rewinding of electric motor copper coil industry.
