Product Brief

5252 Aluminum Sheet, Aluminum Sheet Manufacturer, Aluminum Sheet Supplier. Aluminum Sheet Metal:

5251 aluminum sheet is provided by Henan Mingtai Aluminum with a medium strength alloy possessing good ductility and therefore good formability. 5251 aluminum sheet is known for work hardening rapidly and is readily weldable. Like all the 5000-series high magnesium alloys, 5251 aluminum sheet has a fairly high strength and is hardenable to a significant degree by cold working, enabling a series of H tempers and conforming to ASTM B209M.


Temper Types

The most common tempers for 5251 aluminium are:

H24 - Work hardened by rolling then annealed to half hard

H26 - Work hardened by rolling then annealed to three-quarter hard

O - Soft

H22 - Work hardened by rolling then annealed to quarter hard

 

Weldability

Aluminium alloy 5251 is a readily weldable alloy.

The recommended filler wire is 5356 when welding alloy 5251 to itself, 6XXX series alloys, 7XXX series alloys and most other 5XXX alloys.

When welding alloy 5251 to 5005, 5020, 1XXX series or 3XXX series alloys, the recommended filler wire is 4043.

Weldability – Gas: Very Good

Weldability – Arc: Very Good

Weldability – Resistance: Very Good

Brazability: Poor

Advantages

5251 aluminum sheet contains nominally 2.0% magnesium & 0.30% manganese. It has good workability, high fatigue strength, medium static strength, good weldability and very good corrosion resistance, especially in marine atmospheres. It also has the low density and excellent thermal conductivity common to all aluminium alloys. Aluminum 5052 is commonly used in sheet, plate and tube form
