4045 brazing material in coil form

4045 brazing material in coil form is also called aluminum alloy brazing sheet. When brazing aluminum alloy using brazing under vacuum, vacuum brazing, flame brazing, high frequency brazing, etc., it is supplemented with aluminum brazing solvent. (Commonly known as aluminum solder) will work better together. When the aluminum alloy is brazed, the difference between the melting points of the brazing material and the weldment is very small, so it is more accurate in terms of temperature adjustment than other brazing requirements.


 
Chemical composition of 4045 brazing material in coil form:
Al (minimum): balance
Silicon Si: 9.0 ~ 11.0
Fe: ≤0.8
Copper Cu: ≤0.30
Manganese Mn: ≤0.05
Mg: ≤0.05
Zinc: ≤0.10
Titanium: ≤0.20
Other unspecified elements: each: ≤0.05; total: ≤0.15
 
The advantages of 4045 brazing material in coil form :
For irregular solder joints, due to the use of ordinary welding rings, there is a problem of high welding failure rate;
Manual welding has the problems of unstable welding quality and low welding efficiency;
Welding pads are designed according to the shape of the solder joints, which can not only pack the welding quality, but also realize automatic production.
Production.
