1060-O aluminum plate VS 1060-H24 aluminum plate

1060 aluminum plate is a pure aluminum alloy with an aluminum content of 99.6%. It is a commonly used aluminum alloy. Good elongation and tensile strength make the cheap 1060 aluminum plate highly praised in the market.

First of all, we need to know that the O state is a state of the aluminum plate, which is the product of the aluminum plate after annealing. Aluminum alloys of the same grade are divided into two different forms: O state and H state.

The O-state aluminum plate is formed by crystallization after complete annealing.

H24 is a state of incomplete annealing after work hardening.

Physical properties

The O-state aluminum plate is softer, while the H24-state aluminum plate is harder than the O-state. That is to say, the hardness of the 1060 aluminum plate in the H24 state is greater than that of the 1060 aluminum plate in the O state.

Scope of use

Because the O-state aluminum plate is relatively soft, it is easy to bend and draw. It is mainly used in decoration, packaging, and other industries.

The H24 state is relatively hard and can be drawn, sheared, and bent. It is generally used in curtain walls, mechanical processing and other industries.

Strength

1060-H24 aluminum plate generally exhibits higher tensile strength compared to 1060-O. This means it can withstand higher loads or stresses without permanent deformation.

The higher strength of 1060-H24 makes it suitable for structural applications where mechanical strength is a primary concern, such as construction or automotive components.

Surface finish

Due to differences in manufacturing processes, the surface finish of 1060-H24 aluminum plates tends to be smoother and more uniform than that of 1060-O.

For applications where aesthetics or surface appearance is important, such as architectural or decorative uses, a smoother surface finish may be desirable.

Machinability

While both types can be machined, 1060-H24 may require more specialized tools or techniques due to its higher hardness.

Machining 1060-H24 aluminum plate may require slower cutting speeds and more frequent tool changes compared to machining 1060-O, which impacts manufacturing efficiency and cost.

Corrosion resistance

Due to the inherent properties of aluminum, both 1060-O and 1060-H24 aluminum sheets have excellent corrosion resistance.

However, the work hardening process involved in producing 1060-H24 may result in slightly better corrosion resistance in certain environments or under specific conditions.

Formability

1060-O aluminum sheet is easier to shape and shape due to its softer state, making it better suited for applications requiring complex shapes or deep drawing.

The higher formability of 1060-O makes it suitable for applications such as packaging that require complex designs or tight tolerances.

Weight

Due to the density difference caused by work hardening, the weight of 1060-H24 aluminum plate may be slightly higher than that of 1060-O for the same volume of material.

While the weight difference may be small, it can be considered in applications where weight reduction is a priority, such as aerospace or automotive design.

Surface treatment

The hardness of 1060-H24 aluminum makes it more suitable for certain surface treatments, such as anodizing or painting.

The harder 1060-H24 surface provides better adhesion and durability to the surface finish compared to the softer 1060-O surface.

Endurance

In applications where the material is subject to repeated stress or cyclic loading, 1060-H24 may exhibit better durability properties due to its higher strength and hardness.

The increased strength of 1060 H24 helps prevent fatigue failure and extend the service life of components in demanding applications, such as machinery or equipment that is used frequently.

In summary, for applications where high formability is required and strength is not a primary consideration, choose 1060-O aluminum plate. For applications requiring a balance between formability and strength, choose 1060-H24 aluminum sheet. Consider your project's specific requirements, such as molding process, mechanical properties, and intended use, to make the appropriate selection.
