400g – 2.4mm ER4047 Aluminium TIG Filler Wire Rods

Premium ER4047 aluminum TIG filler rods engineered for industrial-grade welding and brazing applications. With exceptional fluidity, low melting point, and crack-resistant properties, these rods deliver bright, clean welds ideal for critical repairs and high-temperature scenarios.

Applications

Ideal for cylinder head repairs, aluminum heat exchangers, thin material welding, leakproof joints, and high-temperature applications. Perfect for both welding and brazing tasks requiring precise, durable results.

Core Performance

Features a narrow freezing range and superior flow characteristics, ensuring minimal porosity and fusion defects. The high silicon content enhances shear strength and resistance to hot cracking, making it suitable for sustained elevated temperature use.

Quality Assurance

Each rod is individually stamped/laser engraved with grade identification. Our premium fillers undergo strict quality control to ensure consistent performance, free from common defects found in inferior wires. Sturdy packaging prevents damage during transport.

Differentiation

Unlike generic aluminum fillers, our ER4047 rods offer traceable grade marking, industrial-grade purity, and MDR-compliant certification. The superior fluidity and low melting point provide unmatched precision in critical welding applications.

FAQ

Q: Can this be used for anodizing applications?
A: Not recommended for color-matching after anodizing, as the high silicon content typically results in a dark grey finish.
Q: Is this suitable for thin aluminum sheets?
A: Yes, excellent for thinner materials requiring leakproof joints due to its controlled fluidity.
Q: What’s the difference between ER4047 and ER4043?
A: ER4047 has higher silicon content, lower melting point, and superior fluidity compared to ER4043.
