5251 Aluminium sheet Overview

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 is commonly used in marine, coastal environments.

5251 alyuminiy varaq Temperlash

5251 alloy aluminum sheet can be provided in different tempers to achieve specific mechanical properties and characteristics. The common alloys include:

H22 - Work hardened and partially annealed to a quarter hard state

H24 - Work hardened and partially annealed to a half hard state

H26 - Work hardened and partially annealed to a three-quarter hard state

O – Wrought and fully annealed

The choice of temper for 5251 alyuminiy qotishmasi, or any aluminum alloy, depends on the specific requirements of your application. If you need a balance of strength and workability, H22 is a common choice. Biroq, if higher strength is required at the expense of some formability, you might opt for a higher number, like H32 or H34. Conversely, if formability is more critical, you might consider a lower number or the "O" jahl. It's essential to consult with aluminum suppliers or manufacturers to select the right temper for your specific application.

5251 alyuminiy varaq Welding

Baho 5251 Aluminium alloy is a good weldable alloy.

When welding this alloy to itself it is recommended that use filler wire is 5356.

Filler wire 5356 is also recommended if you are welding 5251 alloys to an alloy of the 6000 seriya, 7000 series and the majority of 5000 seriya.

If you are welding either 5251 uchun 5005 yoki 5020 or an alloy of the 1000 series and the 3000 series of alloys then we suggest you use filler wire 4043.
