| ¡¡¡¡¡¡¡¡¡¡* Aluminum base series filler metals | |
ONE: Operation Introduction  ¡¡¡¡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 . |
| TWO: Product Specification 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. |
