【 Featured Products 】
Nickel base filler metal grades: BNi-2, BNi-7
Introduction: BNi-2 filler metal is the most widely used nickel base high temperature filler metal. braze
In the process, it has good wettability, and the joint has excellent oxidation resistance and corrosion resistance
Performance. Suitable for brazing stainless steel, heat-resistant steel and superalloy working at high temperature
Parts. BNi-7 has the lowest melting temperature among nickel-based brazing metals, 14% Cr element
At the same time, good heat resistance and corrosion resistance of the filler metal were ensured. In the brazing process, BNi-7
The filler metal has excellent fluidity and can flow into close-contact joints.
Copper base filler metal containing titanium grade: BCuSnTiIntroduction: CuSnTi filler metal is mainly used in brazing diamond tools. Ti is a strong carbide active element and is also high
The strength of the connection element can generate TiC on the diamond surface as an intermediate layer, improve the diamond surface wettability, to improve
Combine strength for purpose.
Silver base filler metal grade: BAgCu28
Introduction: BAgCu28 filler metal is a kind of eutectic alloy filler metal, alloy melting point
780℃, brazing process has good wettability, strong joint filling ability, and can
Enough to form high strength, high conductivity and corrosion resistance of brazing joints, widely used in electricity
Device welding, can also be used for brazing low carbon steel, stainless steel, superalloy, copper and
Copper alloy, Var alloy and refractory alloy, etc.
