5251 Alyuminiy varaqning umumiy ko'rinishi
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 qotishma korroziyaga nisbatan yuqori qarshilik tufayli ham mashhur va odatda dengizda qo'llaniladi, qirg'oq muhitlari.
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. Aksincha, 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.
