Item Name: Phosphor Copper Welding Rod Material: Copper Melting Point: Melting Point 600 Degrees Celsius Features: Widely Used, Easy to Use, Self-brazing Phosphor Copper Electrode: BCU93P, BCU91PAG Cu: Margin Brazing Temperature: 710 Degrees Celsius -810 Degrees Celsius Specifications: 1: Flat, 2: 1.0mm, 3: 1.6mm, 4: 2.0mm, 5: 2.5mm, 6: 3.0mm Size Details: Round Welding Rod Length: 50cm/19.69" (Approx.) Flat Welding Rod: 50cm x 0.32cm x 0.13cm/19.69" x 0.13" x 0.05" (Approx.) Notes: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Phosphorus copper electrodes do not require flux compatible welding red copper pipes. Phosphorus is a reducing agent that can reduce cuprous oxide and generate phosphorous oxides floating on the surface of the weld. Phosphorus copper electrodes have good fluidity and self-soldering effect. Flux is used compatible other silver-copper electrodes. Package Includes: 10 x Phosphor Copper Welding Rods
