5356 Aluminum Alloy Plate
5356 aluminium alloy is an alloy in the wrought aluminium-magnesium family (5000 or 5xxx series). Unlike most aluminium-magnesium alloys, it is primarily used as welding filler. It is one of the most popular aluminium filler alloys, alongside 4043. It possesses relatively high strength, but at the expense of being more vulnerable to cracking. It is the preferred filler when making lap or butt welds on the popular 6061 aluminium alloy, or when the welded parts are to be anodized.
5356 aluminium alloy is the most widely used welding alloy and can be classified as a general purpose type filler alloy. AL5356 is typically chosen because of its relatively high shear strength. The 5XXX alloy base material, welded with AL5356, possessing a weld pool chemistry greater than 3% magnesium and service temperatures in excess of 150°F will be susceptible to stress corrosion cracking.
