Material: Elkaloy 42  
     
Type of Product: Cadmium containing silver brazing alloy  
     
Application: This is the ultimate commercial silver base brazing alloy when considering:  
     
  a)       Low melting temperature  
  b)       Short melting range  
  c)       Ability to join a wide range of parent metals  
  d)       Strength and ductility of the joints obtained.  
     
  Suitable applications are:  
     
  1. Where a minimum brazing temperature is desirable in order to preserve the properties of the parent metal, to increase the speed of brazing and to eliminate or to limit "finishing"operations.  
     
  2. Where joints have a close and regular joint gap.  (Alloys with short melting ranges are not suitable for bridging large gaps or for building up large fillets.)  
     
  3. Furnace brazing or any other work where the rate of heating is slow and would cause "liquation" in an alloy having a wide melting range  
     
     
  4. Delicate work in which small, neat joints are required.  
     
Physical Properties: Melting range  0  C 608 - 617
  Tensile strength, kgf/mm2 45
  Elongation, per cent 30
  Hardness, Hv 135
  Electrical conductivity, per cent IACS 20
     
Flux Selection: In most cases the use of Elkaflux is recommended.  Specific advice can be obtained from Mallory Alloys Group Technical Department.  
     
Forms of Supplies: The main forms of supply are 1.5mm and 2.0mm rod but other forms available are: wire; strip; foil washers; rings and special shapes.
