WhatsApp: E-mail: Tel: +86 Ⅰ-a: what is a 5251 Aluminium sheet? 5251 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. The 5251 alloy is also popular because of its high resistance to corrosion and ismonly used in marine, coastal environments.Designed for general sheet metal work 5251 (NS4) is an alloyed non-heat treatable aluminium sheet product which is ideal for applications where a greater degree of formability is requiredbined with higher mechanical property characteristics. The alloy is internationally recognised as EN AW 5251 H22 and is AlMg2 hardened to the quarter-hard May 30, 2020 · There are 30 material properties with values for both materials.
