5% 10% 15% Silver Brazing Alloy - Ultimate Metal Fix by China Suppliers & Factory for Copper & Stainless Steel
Material
Advantages
The welding liquid can flow into the depth of the small brazing gap, so that the welded joint has higher strength and toughness, and the strength of the brazed joint can reach more than 90% of the base material.
Working temperature 600°C~900°C, reducing the risk of thermal deformation and brazing time.
The face-centered cubic (FCC) crystal structure of silver (Ag) enables it to undergo plastic deformation without cracking during welding, and silver is the metal with the best known conductivity (IACS 105%). Silver brazing alloys ensure conductivity through high silver content + low impurity control (oxygen content <0.01%).
Appliance
Particularly suitable for replacing split air-conditioning copper pipes, household refrigerators, commercial refrigeration units, filters in refrigeration system accessories, water compressors, etc., to ensure a firm and reliable connection.

Frequently Asked Questions
What are the primary chemical elements in these silver brazing alloys?
Our silver brazing alloys are composed of Silver (Ag), Copper (Cu), Phosphorus (P), Zinc (Zn), and Tin (Sn), varying in percentages depending on the specific alloy code.
What is the typical melting temperature range for these alloys?
The working and melting temperatures generally range between 600°C and 900°C (specifically from 605°C to 850°C depending on the Ag content), which helps minimize thermal deformation during brazing.
Which industries and applications are these brazing alloys suitable for?
They are highly suitable for the refrigeration and HVAC industries, including split air-conditioning copper pipes, household and commercial refrigerators, refrigeration accessories, water compressors, motors, and instruments.
Can I order custom sizes for the silver brazing rods?
Yes. While we offer standard Flat (e.g., 1.3x3.2mm) and Round (e.g., 1.5mm, 2.0mm, 3.0mm) sizes, custom sizes can be manufactured according to specific customer requirements.
Why do silver brazing alloys offer superior electrical conductivity?
Silver is the most conductive metal known (IACS 105%). By combining a high silver content with strict control over impurities (such as keeping oxygen levels below 0.01%), our alloys maintain excellent electrical conductivity.
How strong are the joints welded with these silver brazing alloys?
Due to their outstanding wettability, the liquid alloy flows deeply into narrow brazing gaps, creating joints with high toughness and a strength that can exceed 90% of the base material.
