กลุ่ม: Aluminum Alloy
Magnesium Alloy (Al-Mg). AA designation 5556.
Overview
AA 5556 is a high-strength aluminium–magnesium welding filler alloy (4.7–5.5% Mg) designed to produce weld joints in 5xxx structures whose strength matches or exceeds that of the base metal. It offers excellent corrosion resistance in marine environments and good as-welded ductility. As filler wire it is used in shipbuilding, LNG storage vessels, cryogenic tanks, and structural marine fabrication.
