Contents: Phosphor (P): 6.6-7.4%; Copper (Cu): Rest. This brazing alloy is close to eutectic crystal composition. It is self fluxing and do not need any brazing flux when soldering copper to copper or copper to brass joints, while for brazing brass to brass parts, Bluefire JFB-102 brazing flux is recommended for best results. - Valued Pack: Each tube contains 21 sticks of 14" long brazing rods, total 0.5 (1/2) pound in weight. GREAT SAVING! - Best Performances: Solidus Temperature: 1310°F / 710°C, Liquidus Temperature: 1508°F / 820°C. Recommended joint clearance: 0.002"/0.007", Fluid Rating: 5. JCuPB brazing rods contain lesser phosphors, resulting a much better plastic performances and a little higher melting points. - Versatile: A popular and economic solution for HVAC, Plumbing and Mechanical repairing. Ideal for gas welding, MIG and TIG welding, contact welding, HF brazing and some furnace welding. Perfect for brazing Copper to Copper, or Brass and Bronze joints in A/C, freezer, evaporator, heat exchange, water heater and etc. Cannot be used to weld iron or steel parts. - High Quality: All Bluefire brazing alloys are manufactured under highest quality control. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B093P5ZQSY | | Best Sellers Rank | #152,100 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #86 in Brazing Rods | | Color | Gold | | Customer Reviews | 4.6 4.6 out of 5 stars (400) | | Date First Available | April 28, 2021 | | Included Components | 1/2 lb Phosphor Copper Brazing Rods | | Item Package Quantity | 1 | | Item Weight | 8 ounces | | Item model number | JCuP B | | Manufacturer | Bluefire | | Material | Copper | | Part Number | JCuP B | | Product Dimensions | 14 x 0.13 x 0.05 inches | | Size | 0.5lb | ## Images ![21 Sticks BLUEFIRE BCuP-2 Half 1/2 lb Self Fluxing Phosphor Copper Brazing Alloy Welding Rods No Need for Flux 0.050" x 1/8" x 14" Industry Professional Grade Propane Gas Soldering Torch Supply - Image 1](https://m.media-amazon.com/images/I/81tsHoL2LcL.jpg) ![21 Sticks BLUEFIRE BCuP-2 Half 1/2 lb Self Fluxing Phosphor Copper Brazing Alloy Welding Rods No Need for Flux 0.050" x 1/8" x 14" Industry Professional Grade Propane Gas Soldering Torch Supply - Image 2](https://m.media-amazon.com/images/I/71qq2zgGCbL.jpg) ![21 Sticks BLUEFIRE BCuP-2 Half 1/2 lb Self Fluxing Phosphor Copper Brazing Alloy Welding Rods No Need for Flux 0.050" x 1/8" x 14" Industry Professional Grade Propane Gas Soldering Torch Supply - Image 3](https://m.media-amazon.com/images/I/71m9acOrCAS.jpg) ![21 Sticks BLUEFIRE BCuP-2 Half 1/2 lb Self Fluxing Phosphor Copper Brazing Alloy Welding Rods No Need for Flux 0.050" x 1/8" x 14" Industry Professional Grade Propane Gas Soldering Torch Supply - Image 4](https://m.media-amazon.com/images/I/71PPftv2soS.jpg) ![21 Sticks BLUEFIRE BCuP-2 Half 1/2 lb Self Fluxing Phosphor Copper Brazing Alloy Welding Rods No Need for Flux 0.050" x 1/8" x 14" Industry Professional Grade Propane Gas Soldering Torch Supply - Image 5](https://m.media-amazon.com/images/I/71WVMhmPT+L.jpg) ## Frequently Bought Together - 21 Sticks BLUEFIRE BCuP-2 Half 1/2 lb Self Fluxing Phosphor Copper Brazing Alloy Welding Rods No Need for Flux 0.050" x 1/8" x 14" Industry Professional Grade Propane Gas Soldering Torch Supply - AUTOKAY 10PCS Stem HVAC AC Schrader System Vacuum 1/4" SAE *1/4" OD *2.75" AC Refrigeration Kit - GSParts Harris Stay-Silv Silver White Brazing Flux Paste for Hi Temperature, SSWF7 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/353816911-21-sticks-bluefire-bcup-2-half-1-2-lb-self](https://www.desertcart.pt/products/353816911-21-sticks-bluefire-bcup-2-half-1-2-lb-self) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-03*
