Product Description RBCuZn-D Brass Welding/Brazing Filler Metal: Technical Summary1. Classification & OverviewAWS A5.8 Designation: RBCuZn-D (formerly celebrated as "Naval Brass")Material Type: Copper-Zinc alloy (Cu-Zn-Sn system) enriched with tin, providing superior corrosion resistance.Key Use: Expertly designed for flawless joining of copper alloys, steel, and cast iron where enduring seawater or chemical corrosion resistance is of utmost importance.2. Chemical CompositionTable 1: Composition (Weight %)CuZnSnFePbSiImpurities58.0-61.0%Rem.0.5-1.5%0.25-1.0%≤0.10%0.04-0.25%≤0.50% totalKey Elements:Sn (Tin): Crucial for enhancing seawater resistance against dezincification.Fe (Iron): Plays a vital role in boosting strength and wear resistance.Low Pb/Si: Essential in reducing hot cracking during critical welding processes.3. Mechanical PropertiesAs-Deposited:Tensile Strength: Ranges from 410-510 MPa, ensuring robust performance.Hardness: 85-105 HB, offering excellent durability.Melting Range: Between 885-900°C (solidus-liquidus), accommodating diverse applications.Corrosion Resistance: Exceptional resilience in seawater, marine atmospheres, and mild acids/alkalis, ensuring longevity.4. ApplicationsMarine Engineering: Ideal for crafting ship propellers, seawater piping, and condenser tubes.Industrial: Perfect for heat exchangers, pump components, and rugged valve bodies.Repair: Optimal for joining or building up manganese bronzes and high-tensile brasses, delivering reliable performance.5. Welding & Brazing GuidelinesProcess Compatibility:Oxy-Acetylene Welding (OAW): Highly recommended for precise cast iron repairs.Gas Tungsten Arc Welding (GTAW/TIG): Optimal for precision joints, using DCEN polarity for best results.Parameters:Flux Requirement: AWS Type FB3-A or borax-based flux, essential to prevent oxidation during processes.Preheat: Maintain between 150-260°C, especially for thick sections or cast iron to ensure integrity.Interpass Temp.: Keep ≤200°C to effectively avoid Zn fuming.6. Handling & SafetyZinc Fume Hazard: Employ state-of-the-art local exhaust ventilation (LEV) systems combined with OSHA-approved respirators to ensure optimal safety and health standards.Storage: Preserve in sealed containers with humidity levels maintained below 40% to effectively prevent oxidation and sustain product quality.Form Availability: Available in rods of 3-6 mm diameter, as well as convenient coil forms for versatile use across various applications.7.
