Brazing Alloy for Light Metal Joints ®
EutecRod 1804
BRAZING • Good for tight to moderate joint clearances • Self-fluxing in copper to copper applications • Withstands constant service temperatures up to 300°F (150°C)
DESCRIPTION:
BRAZING METHOD:
EutecRod 1804 is a copper-phosphorus alloy. Excellent brazeability on copper-base alloys when used with FloTectic 1100 or XuperBraze 100 fluxes.
Preparation: Clean joint area with RotoClean® OS or use a VOC-free solvent. Align parts and preheat locally to facilitate quicker joint area heat-up. When brazing copper to brass or bronze paint joint area and rod with FloTectic® 1100.
TECHNICAL DATA: 2
Typical Tensile Strength: 50,000 psi (345 N/mm ) Solidus*: 1190°F (645°C) Liquidus**: 1325°F (720°C) Max. Brazing Temp.: 1500°F (815°C) Electrical Conductivity: 9.5% IACS Electrical Resistivity: 18.2 MichrOhm-cm Heating Method.: Oxy fuel torch, induction and furnace brazing * The solidus temperature is the highest temperature at which the part remains solid i.e. the start of melting. **The liquidus temperature is the lowest temperature at which the part is molten i.e. complete melting.
TYPICAL APPLICATIONS: EutecRod 1804 is an economical alloy for repairing radiators, joining various plumbing connectors, air-conditioning coils, copper tubing. Minimal clean-up required. Water and brushing are sufficient when necessary.
Technique: Use a 2x carburizing flame to prevent oxidation. After preheating, deposit filler metal using a continuous “drop-and-melt” technique. Note that 1804 is very fluid. Make sure that joint gaps do not exceed 0.005”. Continue until the joint is slightly overfilled. Note: When using a flux any “glassy” residue can be readily removed by light scraping. Post-Brazing: If necessary, parts can be cooled in water.
HEALTH AND SAFETY: Observe normal brazing and welding practices, respiratory protection and proper air flow pattern advised. For general welding and brazing practices, see AWS publications Z49.1 “Safety in Welding and Cutting and Allied Process”. Welding and brazing are completely safe processes when performed in accordance with proper safety measures. Become familiar with local safety regulations before beginning welding or brazing operations. DO NOT operate brazing or welding equipment or use brazing and welding materials before you have thoroughly read the proper instruction manual(s). Please refer to the Eutectic internet site for Material Safety Data Sheet (MSDS) information. DISREGARDING THESE INSTRUCTIONS, AND/OR THE INSTRUCTIONS OF BRAZING EQUIPMENT OR MATERIAL MANUALS, MAY BE HAZARDOUS TO YOUR HEALTH.
