MIG/MAG WIRES (GMAW)ALUMINUM WIRESOK Autrod 4043esab.com/fillermetalsOK Autrod 4043 is one of the most widely used welding and brazing alloys and can be classed as a general purpose filler alloy. The silicon additions result in improved fluidity (wetting action) to make the alloy a preferred choice by welders. The alloy is not sensitive to weld cracking and produces bright and almost smut free welds. Not recommended for anodizing. Non-Heat treatable.SpecificationsClassificationsSFA/AWS A5.10 : ER4043 EN ISO 18273 : S Al 4043 (AlSi5) JIS Z 3232 : A4043 ApprovalsCE : EN 13479 CWB : ER4043 DB : 61.039.05 JIS : JIS Z 3232 VdTÜV : 12187 Alloy TypeAlSiTypical Tensile PropertiesConditionYield StrengthTensile StrengthElongationAs Welded55 MPa124 MPa18 %Typical Wire Composition %MnSiAlCuTiZnFe0.015.00Rem0.020.010.010.14Recommended Welding ParametersCurrentWire DiameterVoltage60-170 A0.8 mm13-24 V100-130 A0.8 mm18-22 V125-150 A0.8 mm20-24 V60-170 A0.9 mm13-24 V125-150 A0.9 mm20-24 V85-120 A0.9 mm20-23 V170-190 A0.9 mm21-26 V90-210 A1.0 mm15-26 V140-260 A1.2 mm20-29 V125-150 A1.2 mm20-24 V170-240 A1.2 mm24-28 V180-210 A1.2 mm22-26 V190-350 A1.6 mm25-30 V190-260 A1.6 mm21-26 V260-310 A1.6 mm22-27 V240-300 A1.6 mm22-27 V280-320 A1.6 mm24-28 V290-340 A1.6 mm26-30 V280-400 A2.0 mm26-31 V280-400 A2.4 mm26-31 V280-360 A2.4 mm26-30 V300-400 A2.4 mm26-30 V
