Super Glaze 5356 is our most popular aluminum MIG wire. It is a great general purpose filler alloy designed for the welding of 5XXX series alloys when 40,000 psi (276 MPa) tensile strength is not required. 5356 is often chosen for its high shear strength. It has a low melting point and excellent fluidity. This wire is preferred by welders because of its favorable operating characteristics. This wire is less sensitive to weld cracking and is suitable for sustained elevated temperature service, i.e. above 150 degrees F.
