AG6227 Silver Copper Brazing Alloy

Silver-Copper Hard Solder Description

Silver-Copper Hard Solder is a high-performance solder designed for applications that require high heat resistance, strong mechanical connections, and excellent conductivity. Its properties make it ideal for vacuum systems, aerospace components, medical devices, and highly reliable electronic assemblies.

The Silver-Copper Solder contains no volatile elements and exhibits good wettability on Copper and Nickel, but poor wettability on Steel and stainless Steel. Ag72Cu solder is suitable for vacuum soldering of Copper and Nickel or for soldering in a reducing atmosphere.

Frequently Asked Questions

Q1: Is the Silver-Copper solder suitable for high vacuum applications?

Yes, AgCu28 is ideal for vacuum environments as it avoids flux contamination and ensures a high-quality joint due to its high purity and non-oxidising properties.

Q2: Is the Silver-Copper solder compatible with other metals?

Yes, Silver-Copper Hard Solder bonds well with metals such as:

• Copper
• Nickel
• Gold-plated surfaces
• Stainless Steel
• Aluminium (with appropriate fluxes or treatments)

Q3: What precautions should be taken during soldering?

• Ensure bonding surfaces are clean (free from oxides and oils).
• Maintain a precise heating profile to prevent alloy separation.
• Proceed carefully to avoid thermal shock during cooling.
• Store the solder under dry and temperature-controlled conditions to maintain purity.
