A Brief Introduction to Aluminum Discs

Aluminum discs, also known as aluminum circles, are flat, circular sheets of aluminum that are widely used across various industries.

They offer excellent thermal and electrical conductivity, 耐食性, and lightweight properties, making them an essential material in cookware, 自動車, エレクトロニクス, および産業用アプリケーション.

Aluminum discs are typically manufactured through precise cutting and stamping from aluminum sheets, ensuring high-quality finishes and uniform dimensions.

Common Alloys of Aluminum Discs

Aluminum circles are available in different alloy compositions, each with specific mechanical properties suitable for various applications.

Below is a table summarizing the common aluminum alloys used in aluminum discs:

States of Aluminum Discs

Aluminum discs are supplied in various tempers depending on the mechanical requirements of the end-use application:

• o (アニール): Soft and excellent for deep drawing and spinning applications.
• H12, H14, H16, H18: Work-hardened aluminum circles with different levels of strength.
• H24, H26: Semi-hard conditions, balancing strength and formability.
• T6: Solution heat-treated and artificially aged, offering high strength.

Production Process of Aluminum circles

The manufacturing process of aluminum discs involves several steps to ensure precision, 一貫性, and high quality:

1. 原材料の選択: High-quality aluminum coils or sheets of the desired alloy are chosen.
2. Cutting and Blanking: The aluminum sheet is cut into circular blanks using a blanking press or laser cutting machine.
3. アニーリング (オプション): The aluminum discs are heat-treated to enhance softness and ductility.
4. 表面処理: アプリケーションに応じて, aluminum discs may undergo surface treatments such as anodizing or coating.
5. 品質検査: Each aluminum circle undergoes rigorous quality control to check dimensions, 厚さ, and surface finish.
6. パッケージング: The finished aluminum discs are packed according to industry standards to ensure safe transportation.

Typical applications of aluminum discs

Kitchenware field

In fact, many friends may not know that aluminum discs have entered all aspects of our lives, especially in the field of kitchenware.

Because the entire industry market has changed a lot, many kitchenware have turned to use aluminum circles with low density and light weight to replace them. Take the pots we use in daily life as an example.

We use the new rolling technology to make the pots into three-layer processes.

The first layer is made of stainless steel, the second layer is made of aluminum discs, and the third layer is made of iron.

The pots processed by the three-layer technology not only have the toughness of steel, the long life of iron, and the light density of aluminum.

This is one of the reasons why aluminum circles are now increasingly used in the field of kitchenware, and this data will gradually increase with the development of the market.

Signage field

The field of signage is one of the more common ones we are currently exposed to in the entire market life.

例えば, the round signs we see on the road are generally processed with aluminum discs.

例えば, the no parking signs we see in the garage, or some speed measurement or speed limit signs we see on the highway, all use thicker aluminum circles for back reinforcement.

This is also one of the core application areas of aluminum circles. The advantage is naturally because of the density of aluminum, the small life span and corrosion resistance on the highway or in the open air.

Electronic baseboard field

We may not come into contact with electronic baseboards much, but they have begun to be used in large quantities in all aspects of our lives.

例えば, the baseboards inside the back panels of our monitors or TVs are copper-clad with aluminum circles.

The products displayed after treatment are the applications of electronic baseboards.

同時に, I think many friends have heard about the application of electronic baseboards.

It’s just because we look the same on the surface, but in fact, it is still made of aluminum discs.

Rice cooker liner field

We don’t need to introduce too much about rice cooker liner, which is very common in our lives.

例えば, the rice cookers currently used by larger brands, AD, Haier, Gree, 等, are all stamped with aluminum discs and coated to produce finished products.

Such a product is an electric rice cooker, so for electric rice cookers, it is a place in our lives where aluminum discs are used more and more.

Aluminum container field

This field is a newly developed new field. 例えば, liquid nitrogen liquid is stamped with a new type of aluminum and aluminum alloy, and then used as an aluminum container.

For this field, 6061 alloy aluminum circles or 5052 alloy aluminum discs are generally used.

Because both types of aluminum discs contain magnesium, it is not easy to react chemically with the liquid inside.

同時に, the performance of 6 series and 5 series rolling is better than that of 1 series and 3 シリーズ.

Aluminum discs play a crucial role in various industries due to their excellent properties and versatility.

Whether used in cookware, エレクトロニクス, or transportation, these circles offer reliability and efficiency for manufacturers worldwide.

Understanding the different alloys, states, and production processes helps in selecting the most suitable aluminum disc for specific applications.
