Aluminum Base Series Filler Metals

Aluminum Base Series Filler Metals
  • Product Details

一、 Note the use of
　　The aluminum base filler metals are mainly made up of aluminum and silicon alloy , with a little copper , zinc , manganese , magnesium etc .They can adopt oxyfuel gas welding ， furnace welding ， Vacuum welding , and other welding . They are suitable to braze pure industrial aluminum from L2 to L6 and aluminum alloy such as LF21, LF1 , LD2 , specially aluminum materials .Except for Vacuum welding all the aluminithermic brazing needs to use suitable aluminum flux in the process of brazing . The dregs of a flux on the joint must be completely cleared away after brazing .
二、 Product specifications
The stick-shaped rods whose diameters are between 1.5mm to 4.0mm . and the minute soldering pieces whose thickness are 0.1 to 0.4 mm.
