HITEALLOY

AgCu28 silver based brazing material is currently the most widely used hard brazing material. They have a moderate melting point, good conductivity, high plasticity, high welding strength, high thermal conductivity, and high softening temperature. They also have good corrosion resistance in various media. Silver solder is widely used in device brazing, especially in the temperature range of 600-1100 ℃, and silver solder is the preferred solder.

The most commonly used silver based brazing material is the eutectic Ag72Cu28 alloy brazing material.

Ag72Cu28 silver copper alloy has a melting point of 780 ℃, which not only has excellent process properties such as suitable melting point, good wettability, and strong filling ability, but also has high welding quality, which can form high-strength, high conductivity, and corrosion-resistant brazing joints. As a filling material, it is widely used in the welding of electric and vacuum devices, for brazing low-carbon steel, stainless steel, high-temperature alloys, copper and copper alloys, kovar alloys, and refractory alloys.
