What is the purity of 1235 aluminum foil?

Hey there! As a supplier of 1235 aluminum foil, I often get asked about its purity. So, I thought I'd write this blog to break it down for you.

Let's start with the basics. Aluminum foils come in different grades, each with its own unique properties and purity levels. The 1235 aluminum foil is a popular choice in many industries, and understanding its purity is crucial if you're thinking about using it for your projects.

What Does Purity Mean in Aluminum Foil?

Purity in aluminum foil refers to the percentage of pure aluminum in the foil. The higher the purity, the more aluminum and less of other elements are present. This matters because the purity can affect the foil's performance in various applications. For example, high - purity aluminum foils are often more resistant to corrosion and have better electrical conductivity.

The Purity of 1235 Aluminum Foil

The 1235 aluminum foil is known for its relatively high purity. Typically, it contains at least 99.35% pure aluminum. The remaining percentage is made up of trace elements such as iron, silicon, copper, manganese, magnesium, zinc, and titanium. These trace elements are present in very small amounts, usually less than 0.65% in total.

The presence of these trace elements isn't necessarily a bad thing. In fact, they can enhance certain properties of the aluminum foil. For instance, a small amount of iron can improve the foil's strength, while silicon can enhance its formability. However, the exact composition of these trace elements needs to be carefully controlled to ensure that the foil meets the required standards.

Comparing 1235 Aluminum Foil with Other Grades

It's always helpful to compare 1235 aluminum foil with other common grades to get a better understanding of its purity.

• 1060 Aluminum Foil: This grade has a purity of around 99.6%. It's even purer than 1235 aluminum foil. The higher purity makes it a great choice for applications where high corrosion resistance and good electrical conductivity are required, such as in the electronics industry.
• 1100 Aluminum Foil: With a purity of about 99%, 1100 aluminum foil is slightly less pure than 1235. It's often used in applications where formability is more important than high - end performance, like in packaging.
• 1070 Aluminum Foil: This grade has a purity of approximately 99.7%. Similar to 1060, it's very pure and is suitable for applications where high - quality aluminum is needed, such as in chemical processing equipment.

Applications of 1235 Aluminum Foil Based on Its Purity

The purity of 1235 aluminum foil makes it suitable for a wide range of applications.

Packaging

In the packaging industry, 1235 aluminum foil is a popular choice. Its relatively high purity means it's resistant to corrosion, which helps to protect the contents of the package. Whether it's food, pharmaceuticals, or other consumer goods, 1235 aluminum foil can keep them fresh and safe from external factors.

Electronics

In the electronics field, the electrical conductivity of 1235 aluminum foil is put to good use. It can be used as a shielding material to protect electronic devices from electromagnetic interference. The high purity also ensures that the foil doesn't introduce unwanted impurities that could affect the performance of the electronics.

Heat Exchangers

1235 aluminum foil is also used in heat exchangers. Its ability to transfer heat efficiently, combined with its corrosion resistance due to its purity, makes it an ideal material for this application. It can help to improve the energy efficiency of heating and cooling systems.

Quality Control of 1235 Aluminum Foil Purity

As a supplier, we take quality control very seriously when it comes to the purity of 1235 aluminum foil. We use advanced testing methods to ensure that the foil meets the required purity standards.

We start by carefully selecting the raw materials. Only high - quality aluminum ingots are used in the production process. During the manufacturing process, we monitor the composition of the alloy continuously. Samples are taken at regular intervals and analyzed using techniques such as spectrometry to determine the exact percentage of aluminum and trace elements.

If the purity doesn't meet the standards, we take immediate corrective actions. This could involve adjusting the alloy composition or changing the production parameters. By doing so, we can ensure that every roll of 1235 aluminum foil that leaves our factory is of the highest quality.
