Er4047 Er4043 Aluminium Filler Wire. 030"". 035 3/64"

Er4047 Er4043 Aluminium Filler Wire. 030"". 035 3/64". Versatile Al-Si Filler: ER4043 aluminum welding wire with ~5% silicon, the go-to choice for general 6xxx series welding. High-Silicon Formula: ER4047 aluminum welding wire with 11- 13% silicon, near the Al-Si eutectic point for outstanding performance . Good Fluidity: 4043 Offers smooth weld pool flow, making it easy to fill joints on 6061, 6063 and 6000-series aluminum frames. Superior Fluidity: Flows into tight joints and thin gaps far better than ER4043 - perfect for brazing, castings and thin-wall parts . Fine Anodized Color Match: ER4043 Produces a light gray bead after anodizing, close to the base metal - ideal for architectural and visible parts . Low Melting, Low Shrinkage: Melts around 577-582, about 50 degrees Celsius. lower than ER4043, with minimal distortion and shrinkage. Excellent Hot Crack Resistance: Narrow freezing range (only about 10 degrees Celsius) makes ER 4047 aluminum welding wire highly resistant to hot cracking, even on crack-sensitive 6xxx alloys . Stable Feeding: Precision-drawn surface and tight diameter tolerance of SWT ER4043 ensure trouble-free feeding in both MIG and TIG welding . Built for Thin & Cast Parts: SWT ER4047 is the preferred filler for aluminum castings, engine blocks, heat exchangers and automation-grade thin sheet welding . Brazing Ready: ER4047 works great for aluminum brazing and pairs perfectly with welding flux for clean, strong joints.
