430 UHV SOLDER

430超高真空焊锡


     Use for all metals with the exception of alu- minum. Low temperature solder often used in residential HVAC. Flows quickly to penetrate tight clearances. Extremely versatile, 430 silver-bearing solders are widely used through-out the industry as a better-than-brazing method in many situations.


Chemical Composition : 4% Ag     96% Sn

Specifications : ASTM B32 SN96    NSF 51 J-STD-006   SN96AG04A

Solidus : 430°F      221°C

Liquidus : 430°F      221°C

 

The important advantage of 430 solder is the greater strength of the overall component. After joining, its lower working temperature eliminates the weakening of the base metals caused by annulment from high brazing heat. The result is a stronger, more economical joint.

430 silver bearing solders have the same excellent affinity as Safety-Silv alloys for bonding with most of the ferrous and nonferrous alloys (including stainless steel, nickel, copper, brass, etc.) It provides a considerably higher than necessary elongation for sound dissimilar metal joints  and vibration applications. 430 alloys range in temperature from 430°F to 535°F.

430 solder eliminates oxide scale formed from brazing heat. No nitrogen purge is required for HVAC/R tubes. They are cadmium free and nontoxic.

430 is a eutectic alloy with a single melting point of 430°F (221°C).
