CUTEK COPPER BRAZING ROD

Self-Fluxing on Copper: The most significant advantage. The phosphorus content acts as a flux when joining copper to copper, eliminating the need to purchase, apply, and clean up a separate flux agent. This saves time, money, and labor.
Economical Price Point: Copper-Phosphorus rods are generally the most cost-effective filler metal for copper joining compared to silver-bearing alternatives.

High Strength: The resulting brazed joint provides a high-strength connection (often quoted with tensile strengths around 40,000 psi for similar alloys), making it suitable for high-pressure systems like refrigeration lines.
Good Fluidity (Flow): The alloy melts and flows quickly (low viscosity) by capillary action, allowing it to penetrate tightly fitted joints (required clearance is typically $<0.005$ inches) for a complete and leak-proof seal.
Corrosion Resistance: The joint created by a copper-phosphorus alloy offers good corrosion resistance in most environments, making it durable for water and refrigerant lines.

Self-Fluxing	Typically, copper-phosphorus alloys used for brazing copper to copper are self-fluxing (no external flux needed).

Copper brazing rods like Cutek are primarily used for:

Joining Copper to Copper: This is the most common application, especially in systems where a flux is not desired or required.
HVAC-R Industries: Widely used for joining copper tubing and pipes in heating, ventilation, air conditioning, and refrigeration systems.
Plumbing: For connecting copper water pipes.
