  • Copper Aluminum Solder Flux Lead Free Stainless Steel Material With No For - China

    price: contact company for price

    copper aluminum solder flux lead free solder stainless steel

    solder material with no flux for aluminum copper pipe solder


    Stainless steel solder material with no flux non corrosion

    brazing filler metal alloy JH-004BXG series

    Research background

    Recent year, stainless steel tube with thin tube wall widely

    used in household electric appliance refrigeration industry

    ; but traditional stainless steel pipe welding has 3

    disadvantages .

    1. The price is much higher using the silver solder

    2. If using Corrosive solder flux, it is easy to cause

    solder Corrosion once entering inside of pipe,

    3. Solder welding temperature is high, because the stainless

    steel tube wall is very thin that easy be oxidated,

    especially the internal wall of pipe, the black oxide skin

    is difficultly to remove.

    For a few decades, domestic and foreign experts in brazing

    technology research, has been in the pursuit for the

    solution of soldering technology of stainless steel low

    temperature without corrosion, but a little results.

    Jinghang brazing technology R&D team have broken the world

    top problem after several years effort. The stainless steel

    solder with no Corrosive flux can be welded in the

    temperature arrange :380C~450C, the brazing performance is

    excellent , for easily operate with low brazing temperature;

    it is wildly applied in brazing of different stainless steel

    pipe .


    1.Stainless steel solder with no Corrosive flux

    Alloy system is composition of Sn-Ag rare earth quaternary

    alloy, brazing temperature :380-450C

    can be made into diameter of 1.0-3.0 brazing rod ; strength

    is 300MPa-400 MPa It can be changed according to its work-

    hardness capacity.

    2.Brazing performance

    JH-004BXG brazing filler metal by flame brazing and high

    frequency brazing heating, it has good extension performance

    in stainless steel surface ; it has good seam filling

    performance when weld the stainless steel tube wall . As the

    filler metal melt temperature is below 450C, which is much

    lower than high silver filler metal (melt temperature

    680C). So in brazing , the stainless steel base metal is so

    soft enough to avoid the brazing welding stress and tiny

    cracks and improve the air tightness .

    Type No:JH-004BXG-P

    Composition :Sn Al Ag rare earth and no Corrosive flux

    Specification: Diameter of section φ1.6mm φ2mm

    2kg /roll 5kg /roll

    Shape : rod , wire , ring wire , paste

    Usage: suitable for brazing welding in stainless steel pipe

    Brazing way :

    manual Flame brazing

    Auto flame brazing

    high frequency brazing

    Furnace brazing

    remark : 1 brazing seam should be loose

    2 thickness of stainless steel pipe wall should be less than


    3.let welding parts be there for one minute after brazing .

    Type No:JH-004BXG-G

    Usage: suitable for brazing welding in stainless steel pipe
