Silver base copper phosphorus environmental protection solder (silver copper phosphorus solder) grade and performance

(1) HaG-2B silver 2% equivalent to American standard AWS BCUP-6, NATIONAL standard BCu91PAg and L209, has good fluidity and filling capacity, widely used in air conditioning, refrigerators, mechanical and electrical industries, copper and copper alloy brazing. Melting point is 645-790 degrees Celsius.

The silver content of HAG-5B is 5% equal to that of AWS BCUP-3 GB BCu88PAg and L205. It has certain plasticity and is suitable for the welding of copper and its alloy joints that cannot keep close fit. Melting point is 645 to 815 degrees Celsius.

(3) HAG-15B contains 15% silver equivalent to American AWS BCUP-5 gb BCu80AgP and L204, with good joint plasticity, improved electrical conductivity, especially suitable for uneven clearance occasions. Brazing of copper and its alloy joints that can bear vibration load. Melting point 645-800 degrees Celsius.

Comparison table of common silver solder:

Hyag-50b silver electrode (silver wire, silver plate), melting temperature: 690-775 Used for welding of electronic, food and materials subjected to vibration loads.

Hyag-47b Silver electrode (silver wire, silver sheet) melting temperature: 663-730 Good comprehensive performance, excellent toughness and permeability, good tensile strength. It is commonly used for brazing mechanical and electrical, food and parts with higher requirement of smooth surface.

Hyag-45b silver electrode (silver wire, silver welding sheet) melting temperature: 645-680 Good process performance, joint can withstand vibration load, is the most widely used silver material

Hyag-40b silver electrode (silver wire, silver solder) melting temperature: 600-630 low melting point, excellent process, suitable for quenching steel and small thin parts of another brazing.
