EutecRod-1803

Brazing Rod for Copper-To Copper Joints ®

EutecRod 1803

BRAZING • Good for moderate to loose joint clearances • Self-fluxing in copper to copper joints • Excellent choice for light metal HVAC, pipe and electrical applications

DESCRIPTION:

BRAZING METHOD:

EutecRod 1803 is a copper-phosphorus alloy. EutecRod 1803 contains some 15% silver for improved corrosion resistance and flow characteristics in joints where close fits cannot be maintained

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.

Excellent brazeability on copper-base alloys when used with FloTectic 1100 or Xuper Braze 100 fluxes.

TECHNICAL DATA: Typical Tensile Strength: 30,000 to 40,000 psi (207 to 276 MPa) Solidus*: 1190°F (645°C) Liquidus**: 1475°F (800°C) Max. Brazing Temp.: 1500°F (815°C) Electrical Conductivity: 9.9% IACS Electrical Resistivity: 17.3 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.

Technique: Use a 2x carburizing flame to prevent oxidation.

After preheating, deposit filler metal using a continuous “drop-and-melt” technique. Note that 1803 is very fluid.

Make sure that joint gaps do not exceed 0.006”. 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.

TYPICAL APPLICATIONS: EutecRod 1803 has silver-enhanced flowability and groundcontact corrosion resistance.

Use when brazing copper heat exchangers, in-ground electrical connections, copper parts subject to vibration. No clean up is needed due to its self-fluxing properties.

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.
