Along with increasing of silver content,strength will be better.Use for copper and copper,copper and brass parts with shock in air condition and freezer, copper and copper alloy tie-in electric motor mete, Low phosphor content suitable for ample clearance, high phosphor content suitable for gap tie-in.

• 15% Silver Bearing: USA AWS A5.8 Class: BCuP-5 brazing alloy rods. Contents: Silver (Ag) 14.5-15.5%; Phosphor (P): 4.8-5.2%; Copper (Cu): Rest. For the best results, recommend to be use with Bluefire JFB-102S brazing flux.
• Valued Pack: Each tube contains 20 sticks of 14" long brazing rods, total 0.5 (1/2) pound in weight (Minor weight difference might exist in each tube, which is normal). GREAT SAVING!
• Best Performances: Solidus Temperature: 1193°F / 645°C, Liquidus Temperature: 1472°F / 800°C, Recommended Joint Clearance: 0.002"/0.006", Fluidity Rating: 3. The 15% silver contents greatly improve the performance of the brazing alloys, providing better wettability, higher strength and lower melting temperature. Consequently, making the welding fluids capable to flow deeply into the small brazing gap, providing higher strength and toughness of the welding joint, and reducing the brazing time.
• All-Purpose: A Must-Have for HVAC, Plumbing and Mechanical repairing.Perfect for both professionals and DIY. Ideal for brazing or filling of Copper to Copper, or Brass and Bronze joints with small to medium gaps, especially suitable for parts that requiring higher strength and vibrating resistances, such as air-conditioners, refrigerators and freezers, compressors, electrical motors, and etc.
• High Quality: All Bluefire brazing alloys are manufactured under highest quality control. Equivalent to HARRIS STAY SILV 15 or SIL-FOS 15% silver brazing rods, with more affordable price!
