Radnor ER4043 Aluminum-silicon alloy for use on many weldable cast and wrought aluminum alloys. Radnor 4043 rod is generally recommended for welding 5052, and any 6000 series alloys and castings.

• Manufactured under a quality system certified to ISO 9001 requirements
• 36" cut length rods embossed on each end for ease of alloy identification even after the rod is partially consumed
• Pristine surface condition monitored in the manufacturing process to ensure excellent weld quality.
• The manufacturing process precisely controls the alloy and chemical composition to produce consistent physical characteristics.
