Product Details

5052-H34 aluminum is a half-hard temper of the 5052 aluminum-magnesium alloy. It is commonly selected when a project needs a practical balance between strength, stiffness, corrosion resistance, and forming performance. Compared with softer H32 material, H34 provides higher strength and rigidity, while remaining more workable than harder tempers such as H36 and H38.

What Does 5052-H34 Mean?

The designation combines the alloy number 5052 with the temper designation H34. 5052 belongs to the Al-Mg family and is valued for its corrosion resistance, weldability, and good forming characteristics. The H34 condition indicates that the material has been strain hardened and stabilized to a half-hard condition.

Quick interpretation: 5052 = alloy grade; H = strain-hardened condition; 34 = stabilized half-hard temper.

5052 Temper Selection: O to H38

The main difference between 5052 tempers is the balance between strength and formability. As the degree of work hardening increases, strength generally rises while elongation and deep-forming capability decrease.

Temper	Hardening Level	Formability	Typical Selection Logic
O	Annealed	Excellent	Deep forming and complex shapes
H32	Quarter-hard	Very good	Forming with moderate strength
H34	Half-hard	Good	Balanced strength and forming
H36	Three-quarter-hard	Moderate	Higher strength and stiffness
H38	Hard	Lower	Maximum strength among common H tempers

Why Choose H34?

H34 is often used when a sheet must remain formable but cannot be too soft. The additional work hardening improves resistance to deformation and provides better stiffness for panels, enclosures, brackets, transportation components, and general fabricated parts.

For many fabrication projects, H34 sits between easy forming and structural rigidity. It can therefore reduce the need to move to a harder temper when moderate strength is sufficient.

5052-H34 vs H32: Which One Should You Choose?

Requirement	H32	H34
Formability	Higher	Good
Strength	Lower	Higher
Stiffness requirement	Moderate	Better suited
Deep bending	Preferred	Requires radius evaluation
Typical decision	Formability first	Strength and forming balance

H34 vs H36: When Does Higher Strength Make Sense?

H36 provides greater work hardening than H34, so it can be useful when panel stiffness and resistance to permanent deformation are more important than forming flexibility. However, increased hardness also makes bending more demanding.

For components requiring repeated or relatively tight bends, the specified inside radius should be checked against alloy, thickness, grain direction, and forming method. A generic radius should not be applied to every 5052 thickness.

Practical rule: Choose H32 when forming is the priority, H34 when strength and forming must be balanced, and H36 when additional strength or stiffness is more important.

Typical Mechanical Properties

Mechanical properties vary with thickness and the applicable product specification. The following values should therefore be treated as a practical reference rather than a substitute for the material certificate or governing standard.

Temper	Relative Tensile Strength	Relative Yield Strength	Relative Elongation
H32	Moderate	Moderate	Higher
H34	Higher	Higher	Moderate
H36	High	High	Lower

5052-H34 Sheet Availability

Common commercial thicknesses can range from approximately 0.5 mm to 6 mm, depending on the mill, width, temper, and order quantity. Availability should be confirmed by the exact combination of thickness, width, surface condition, edge condition, and certification requirements.

For standard fabrication, buyers should avoid specifying only the alloy number. A complete inquiry should identify the applicable standard, temper, thickness, width, length, quantity, and any required inspection documentation.

How to Order 5052-H34 Correctly

Example purchasing description:

ASTM B209 5052-H34 aluminum sheet, 1.5 mm × 1000 mm × 2000 mm

For production orders, the description should also state quantity, tolerance requirements, surface condition, edge condition, packing requirements, and inspection documentation. If the material will be used for pressure, marine, transportation, or other regulated applications, the required certification should be stated before production.

Commercial Supply and Custom Processing

For buyers who need more than standard sheet supply, aluminum sheet sourcing can be combined with cutting, sizing, bending, surface protection, and other fabrication requirements. Teda Ganghua can support specification-based sourcing for different aluminum grades and tempers, helping buyers match the required alloy condition with the intended fabrication process.

A practical supply program can also combine standard sizes with custom-cut sheets. This can reduce downstream processing when the required dimensions are known in advance, while documentation and material identification can be maintained throughout the order.

FAQ

Is 5052-H34 good for bending?

Yes. It has good forming capability, but it is less ductile than H32. The required bend radius should be evaluated according to thickness, forming direction, and fabrication method.

Is H34 harder than H32?

Yes. H34 represents a higher degree of strain hardening than H32, so it normally provides higher strength and stiffness with somewhat reduced formability.

Should I choose H34 or H36?

Choose H34 when a balance between strength and forming is required. H36 is more appropriate when higher strength or stiffness is prioritized and the component does not require demanding bends.

What information should be included in a 5052-H34 inquiry?

Specify the alloy, temper, applicable standard, thickness, width, length or sheet format, quantity, tolerance, surface requirements, edge condition, and required certification. This prevents ambiguity during quotation and production.

Can 5052-H34 be used for outdoor applications?

Yes. The 5052 alloy is known for good atmospheric and marine-related corrosion resistance. The final selection should still consider exposure conditions, surface treatment, joining method, and the required service life.
