Description

2.5mm Silver Copper Eutectic Alloy Ag72Cu28 Brazing Wire

Silver-based brazing filler metal is currently the longest and most widely used brazing filler metal in solders. Due to its suitable melting point, good electrical conductivity, high strength and plasticity, good processing performance, and corrosion resistance in the medium Also better.

Ag72Cu28 is widely used as a filler material for the brazing of electric vacuum devices. It is used for brazing low-carbon steel, stainless steel, high-temperature alloys, molybdenum, nickel, copper and their alloys, Kovar and refractory alloys.

Equivalent for Ag72Cu28:

GB/T 10046-2008: BAg72Cu

DIN EN 1044:AG 401

DIN 8513: L-Ag72

EN ISO 3677: B-Ag72Cu-780

AWS A 5.8:BAg-8

Features:

-Eutectic brazing wire, melting point is 780℃

-Good wetting performance

-Good electrical and thermal conductivity

-Excellent mechanical properties

-Corrosion resistance, high reliability of welded joints

-The most widely used solder for electric vacuum devices.
