5251 Aluminum Sheet & Plate

5251 Aluminium Sheets and Plates are used for containers, durniture tubing, marine structures, boats, panelling and pressings, aircraft parts, silos and vehicle panels.


5251 Aluminum Sheet / Plate

5251 aluminum alloy sheet has good machinability, good weldability and good corrosion resistance. Because its composition contains 2.0% magnesium and 0.3% manganese, so it has medium static strength and high fatigue strength. It also has low density and excellent thermal conductivity common to all aluminum alloys.It is widely used in the ocean and atmosphere.

5251 aluminium plate is a medium-strength metal known for its ductility and formability.This grade of Aluminium alloy is best known as a metal that can harden rapidly and is weldable easily.5251 has the same high resistance to general corrosion as other non heat treatable aluminium alloys. It also has the higher resistance to slightly alkaline conditions common to the 5000 series alloys. The resistance of 5251 to corrosion in marine atmospheres is excellent, exceeding that of 5005, hence the frequent use of 5251 in marine applications such as small boats and dinghies.
