OK Autrod 18.22 GMAW
AlMg6MnZr
Description
OK Autrod 18.22 is suitable for welding aluminium alloys with a magnesium
content of more than 3% where high strength is required. The alloy has a small
addition of zirconium that has a fine graining effect that makes it less sensitive to
hot cracking during solidification. Non-heat treatable.
