Nickel Brazing osmosis layer fin tubes:
welding ratio between tubes (pipes) and fins is 100%
no thermal contact resistance
contact resistance of 0, significantly less than the high-frequency welding and copper alloy welding, embedded fin tubes (pipes), similar with single metal fin tubes;
welding parts smooth, uniform layer of alloy infiltration.
Working temperature is about 500 to 600 degree.  |
