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. |

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. |
