Silver Brazing Alloys Bearing Cadmium     Silver Brazing Alloys Cadmium Free     Copper/ Brass Brazing Alloys     Phosphorous Silver Brazing Alloys     Brazing Fluxes                                             We manufacture and export superior quality products our product range includes the following:           Silver Brazing Alloys Bearing Cadmium       PE 50% Cd  & PE 50N  Cd   For brazing tungsten carbide tips to rock drills, milling cutters, cutting and shaping tools, also suitable for brazing steels which are difficult to 'Wet' such as stainless steels. (Flame-neutral)   PE 45% Cd  PE 43% Cd & PE 40%  Cd These alloys are an ideal composition for economy in brazing operation requiring a low temperature, quick amd complete penetration, and neat joints of high strength that need little or no finishing. These alloys are essentially used where joints to employ fitted or where it is desired are closely brazing alloys that will be effective in the widest possible range of application. They  satisfactory results on steel, copper, brass, gun metal, tin bronzes, aluminum and manganese bronzes, copper-nickel alloys and nickel silvers of all types. (Flame-neutral).   PE 35% Cd,  PE 30% Cd, PE 25% Cd & PE 20% Cd Alloys for general engineering metals with excellent capillary flow with better ductility for filling gaps.         Product Composition % Melting Range Specifications Silver Copper Zinc Cadmium Nickel Solidus °C Liquidus °C   IS:2927  BS:1845 DIN-8513 AWS:A5.8 PE50%Cd 50 16 15 19 - 629 637 BaCuAg10 AG1 LAg50Cd BAg1a PE50NCd 50 16 16 15 3 634 688 BaCuAg12 AG9 LAg50CdNi BAg3 PE45%Cd 45 15 17 23 - 605 620 BaCuAg15 - - BAg1 PE43%Cd 43 16 19 22 - 610 620 BaCuAg16A AG2 - - PE40%Cd 40 18 21 21 - 593 628 - AG10 LAg40Cd - PE35%Cd 35 26 18 21 - 610 702 BaCuAg20 AG11 LAg34Cd BAg2 PE30%Cd 30 29 21 20 - 610 700 BaCuAg21 AG12 LAg30Cd BAg2a PE25%Cd 25 35 26 14 - 600 715 - - - BAg27 PE20%Cd 20 39 29 12 - 603 755 - - LAg20Cd -           Silver Brazing Alloys Cadmium Free     Product Composition % Melting Range Specifi-cations Silver Copper Zinc Manganese Nickel Tin Solidus °C Liquidus °C IS:2927 BS:1845   DIN8513   AWS:A5.8 PE 60% 60 29 11 - - - 688 732 BaCuAg6 - - - PE 55% 55 22 18 - - 5 620 653 BaCuAg8 - L-Ag55-Sn BAg-7 PE 50% 50 34 16 - - - 688 774 BaCuAg9 - - BAg-6 PE 49% 49 16 23 7.5 4.5 - 625 705 - AG18 L-Ag49 BAg-22 PE 45% 45 29 26 - - - 677 743 BaCuAg14 AG15 L-Ag44 BAg-5 PE 43% 43 37 20 - - - 688 765 BaCuAg16 AG5 - - PE 40% 40 30 28 - 2 - 660 779 BaCuAg18 - - BAg-4 PE 30% 30 36 32 - 2 - 690 760 - - - - PE 25% 25 41 34 - - - 680 795 - AG17 L-Ag25 -           Copper/ Brass Brazing Alloys       Paras Copper based brazing consumables are produced from pure metals to exact chemical specifications. Our carefully controlled process guarantees a smooth, bright product with consistent brazing properties.     PE Silicon Bronze   For brazing of  tubular and sheet metal joints of steel, copper, galvanized iron, fusion welding of brass  & bronzes.   PE Manganese Bronze   For braze welding cast and malleable iron. Can also be used for building up of worn surfaces.   PE Nickel Bronze   For braze welding steel or malleable iron. Building up worn surfaces and welding copper-zinc-nickel alloys of similar composition.          Product Composition % Melting Range Speci-cations Copper Zinc Silicon Manganese     Nickel Solidus °C Liquidus °C IS:1278 BS:1453 PE SILICON BRONZE 60 39.7 0.3 - - 875 905 SC6 C2 PE MANGANESE BRONZE 60 39.6 0.2 0.2 - 895 920 SC8 C4 PE NICKEL BRONZE 51 39.7 0.3 - 10 910 925 SC9 C5 PE C.N.S 96.7 - 0.60 0.20 2.50 1090 1100 - - PE Ferro Bronze 57.5 38.5 - 2.00 2.00 (Cobalt) 870 930 - -           Phosphorous Silver Brazing Alloys       Paras Brazing alloys are the cleanest and brightest, free of oxide and surface impurities. These brazing alloys are extensively used for joining copper tubing in the refrigeration and air conditioning industries, as well as in other application. Phosphorous acts as a fluxing agent due to its affinity for oxygen, therefore the usual application of a brazing flux may be omitted. However, this type of brazing alloys cannot be used on Ferrous or Nickel alloys because of brittle joints.   Leaks are caused by oxide and impurities. Contamination that enters the joint in the molten metal of an impure brazing alloy and impede the brazing alloy flow. Wherever there is contamination, the alloy flows around it, leaving pinholes in the joint. These pinholes are tiny doors which allow refrigerant gas to leak out. Leaks are expensive, the serviceman has to return to the job to re-braze the joint and must refill the expensive refrigerant that was lost from the leaks.         Product Composition% Melting Range Specifications Silver Phos Copper Solidus °C Liquidus °C IS:2927 BS:1845 DIN:8513 AWS:A5.8 PECopper Phos-A - 7.2 92.8 710 802 BaCuP-2 CP3 L-CuP7 BCuP-2 PE Copper Phos-B - 6.1 93.9 725 830 BaCuP-1 CP6 L-CuP6 - PE 2% 2 6.6 91.4 643 788 BaCuP-3 CP2 L-Ag2P BCuP-6 PE 5% 5 6.6 89 643 816 BaCuP-4 CP4 L-Ag5P BCuP-3 PE 6% 6 6.5 87.5 643 774 - - - BCuP-4 PE 15% 15 5 80 643 804 BaCuP-5 CP1 L-Ag15P BCuP-5         Brazing Fluxes     Application Working Temp °C Silver Brazing 600-800 Brass Brazing 750-950 Drill Rod Brazing 700-900 Ferro Bronze 800-950
