The Lincoln Electric SuperGlaze\u00ae 4043 is a premium aluminum-silicon filler metal designed for high-quality Gas Tungsten Arc Welding (GTAW). This 1\/8-inch (3.2mm) rod is engineered specifically for welding heat-treatable base alloys, particularly the 6XXX series (such as 6061) and 5052, as well as various weldable cast aluminum alloys. The addition of 5% silicon significantly lowers the melting point of the filler metal relative to the base material, providing excellent fluidity and wetting action. This characteristic makes 4043 the preferred choice for welders seeking a smooth bead profile and reduced crack sensitivity in constrained joints.<\/p>\n
Lincoln Electric employs advanced manufacturing processes to ensure the surface of the SuperGlaze rod is exceptionally clean, reducing the risk of porosity and inclusions in the weld deposit. This attention to surface quality translates to better arc stability and a cleaner finished weld. A critical feature for industrial environments is the alloy identification embossed directly onto each rod end. This permanent marking helps quality control managers and welders verify that the correct filler metal is being used, preventing costly material mix-ups in shops that handle multiple aluminum grades.<\/p>\n
Packaged in a durable 10 lb carton, these 36-inch cut lengths are ready for immediate production use. The R4043 classification meets AWS A5.10 standards, ensuring compliance with rigorous code requirements. Whether used for pressure vessels, general fabrication, or architectural aluminum structures, the SuperGlaze 4043 delivers consistent mechanical properties and operator appeal.<\/p>\n","protected":false},"excerpt":{"rendered":"Use on many weldable cast and wrought aluminum alloys.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1965,1959],"product_tag":[],"class_list":["post-1752526","product","type-product","status-publish","product_cat-all-aluminum-mig-tig-wires","product_cat-welding-wires-and-electrodes","pa_aws-spec-er4043","pa_brand-lincoln","pa_diameter-3-2mm-2","pa_diameter-3-2mm","pa_packaging-10lb-tube","pa_packaging-10lb-tube-2","pa_packaging-description-10lb-tube","pa_polarity-ac","pa_position-all-position","pa_position-all-position-2","pa_weld-process-tig","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n
