4047 ALUMINUM
High-Silicon Alloy for
Precision Brazing & Thermal Control
4047 Aluminum is a high-silicon, corrosion-resistant alloy ideal for brazing applications and thermal management systems. Commonly used in the aerospace, automotive, HVAC, and telecommunications industries, 4047 is known for its excellent flow characteristics, low melting point, and strong bond integrity.
We supply 4047 in coil, sheet, and custom-cut formats—processed in-house for your exact specs.
Key Features
- High silicon content (~12%) for excellent brazability
- Superior corrosion resistance
- Lower melting point than 4045 or 6061
- Smooth finish and strong post-braze bond
- Great fluidity and wetting characteristics
- Ideal for clad or multi-layer applications
