BCUP-9 Phos-Copper Brazing Alloy Flux Cored Rod for HVAC & Plumbing Welding
Product Details
Product Overview
The BCUP-9 Phos-Copper Brazing Alloy Flux Cored Rod is a high-performance welding consumable designed for joining copper and copper alloys in HVAC, refrigeration and plumbing applications. The integrated flux core eliminates the need for separate flux application, improving work efficiency and ensuring consistent, leak-proof brazed joints with excellent corrosion resistance and mechanical strength.
Key Features
- Integrated flux core design, no additional flux required for copper-to-copper brazing
- Phosphorus-copper alloy formula provides strong, corrosion-resistant joints
- Low melting point (710-815°C) for smooth flow and easy operation
- Suitable for both manual and automatic brazing processes
- Complies with AWS A5.8 standard for reliable performance
- Ideal for HVAC piping, refrigeration systems and copper plumbing installations
