Hardness of 1000-8000 series alloy aluminum sheets

Introduction to the hardness of 1000-8000 series alloy aluminum sheets

The hardness of aluminum alloys is closely related to the alloy composition, processing technology and heat treatment. However, the hardness of different series of aluminum alloys is different. The following is the difference between aluminum alloy series that we have summarized through our long-term research on aluminum alloy series. Analysis of hardness.

Hardness of 1000 series aluminum plate

The 1000 series aluminum plate belongs to the series of products containing the most aluminum among the entire aluminum plate series. The basic aluminum content is maintained above 99.00%, which is usually called 1000 series pure aluminum;

The 1000 series aluminum plate has a relatively simple production technology, and its price is basically the lowest among the entire aluminum alloy series. The hardness of the 1 series alloy aluminum plate is the lowest among the entire series, and the ordinary plate is more suitable for stamping or decoration purposes.

1000 series aluminum sheets are suitable for applications where strength is not required, and their softness makes them ideal for forming, welding and applications requiring high corrosion resistance, such as food packaging.

Hardness of 2000 series alloy aluminum

The 2000 series alloy aluminum plate is the product with the highest hardness in the all series. The advantage of the 2000 series is its high hardness, especially for stamping parts and parts. 2000 series aluminum alloys will be preferred, such as 2A16/2A06, which are the leading products of the 2000 series, this brand of aluminum alloy is also used in automobile wheels.

Hardness of 3000 series alloy aluminum plate

The 3000 series aluminum plate is basically a rust-proof aluminum plate, and its hardness is harder than 1000 series aluminum plate. Because the manganese element in 3000 series aluminum plates is high, the basic proportion is about 1-1.5%, and the price is slightly higher than that of 1000 series aluminum alloys;

Therefore, 3000 series aluminum alloys are widely used and are generally used in fields where the hardness requirements are slightly higher than those of 1000 series aluminum alloys.

Hardness of 4000 series alloy aluminum

The 4000 series is generally a series with a high proportion of silicon element. It is often called Al-Si alloy. Basically, the silicon content can reach 4.5% to 6.0%. However, the 4000 series products are used less, and most of them are used more for products that require low melting point and good corrosion resistance. Because the advantages of 4000 series alloy aluminum plates are heat resistance, wear resistance and corrosion resistance.

Hardness of 5000 series alloy aluminum plate

The 5000 series aluminum plate is a hot-rolled aluminum plate and has similar uses to the conventional 1000 series and 3000 series aluminum plates. It is generally based on aluminum-magnesium alloy, with a magnesium content of 3-5%. As a common aluminum plate in our lives, 5000 series is widely used in various fields due to its advantages of low density, high elongation and high tensile strength. Moreover, the 5000 series alloy aluminum plate has moderate hardness and mature technology.

5000 series aluminum alloy is a medium-strength aluminum alloy material.

Hardness of 6000 series alloy aluminum plate

The 6000 series aluminum plate is an all-in-one aluminum plate and strip. It basically combines the product advantages of the 4000 series and the 5000 series. The 6000 series alloy aluminum plate has high hardness, corrosion resistance, and forging resistance. In particular, it has good oxidation effect and high aesthetics.

The 6000 series aluminum alloy can be strengthened through heat treatment. The processed state is T4, T6, T651. The 6000 series aluminum alloy strengthened by heat treatment has higher strength.

• 6063 aluminum sheet
• 6082 aluminum alloy

Hardness of 7000 series alloy aluminum plates

7000 series aluminum plate is an aviation series aluminum plate, and the main alloy element is zinc. Among the products after the 2000 series, the alloy aluminum plate has the highest hardness. At the same time, the 7000 series aluminum plate contains aluminum, magnesium, zinc, and copper alloys and does not deform after processing. It has high hardness and high strength.

Hardness of 8000 series alloy aluminum plate

8000 series alloy aluminum plates belong to other series, so the hardness of 8000 series alloy aluminum plates generally does not fall into this comparison category. Because 8000 series alloy aluminum plates are mainly used for bottle cap materials or aluminum foil, there are not many customers who have separate needs in the field of civilian processing.

In summary, as the series number increases, the hardness of aluminum alloys does not strictly increase or decrease, but has its own characteristics according to different alloy compositions and processing techniques. Among them, the 2000 and 7000 series tend to have the highest hardness, while the 1000 series is the softest. Although the hardness of the 5000 and 6000 series is not as good as these two series, they are widely used in practical applications due to their excellent overall performance.

The 3000 series aluminum alloy6063 aluminum sheet is a medium-strength aluminum alloy with excellent price and excellent performance. It is also an extremely widely used aluminum alloy material.

Hardness is not the only factor that determines the suitability of alloy plates. When choosing the best series, consider your specific requirements for strength, weight, corrosion resistance and formability.

The temper designation has a significant impact on the hardness of each series. Be sure to consult a reference sheet or material data sheet for the precise hardness value for a specific temper condition.
