|
|
Bcup-1
|
It is the highest temperature of the P Cu solder widely used in Gas appliances
|
|
Bcup-2
|
Good flow property economical widely used in the brazing of presenting in
air-conditioners and the no-verbatim load areas
|
|
Bcup-3
|
Have certain plasticity suitable for brazing copper alloy and some copper –which can’t conjugate tightly
|
|
BCup-4
|
It is of low melting point It is especially fit for the automatic braze welding it
has been largely applied in the soldering with four way valve and cut-off valve
|
|
Bcup-5
|
Bettered plasticity and conductivity of joint suitable especially for brazing copper and copper alloy with vibration load
|
|
Bcup-6
|
Widely used in brazing copper and copper alloy in the fields of air-conditioning and mechanical-electrical good flow property and filling capability
