Product Description

Alloy Aluminum Painted Sheet For Aluminum Case For Electroylytic Capacitor Making

Product Introduction:

 

The 0.30mm thick Alloy 3003 H24 prepainted aluminum sheet is a specialized material playing a crucial role in the production of electrolytic capacitors. This type of aluminum sheet combines the excellent properties of Alloy 3003 with the advantages of a prepainted finish, making it highly suitable for the demanding requirements of the electrolytic capacitor manufacturing industry.


 

Product Parameters

Alloy 3003 has the following properties:

 

• Mechanical Properties
  • Strength: It has moderate strength. The addition of manganese increases its tensile strength and yield strength compared to pure aluminum, with a typical tensile strength of 145 - 290 MPa and a yield strength of 125 - 255 MPa, depending on the temper.
  • Hardness: It has a relatively low hardness in the annealed state, but can be hardened through cold working. For example, the Rockwell B hardness of the H18 temper is around 60 - 70.
  • Formability: It has excellent formability, allowing it to be easily formed into various shapes by processes such as rolling, bending, and stamping without cracking or excessive springback.
  • Ductility: It has good ductility, enabling it to undergo significant plastic deformation before fracture. The elongation at break can range from 20% to 40% in different tempers.
• Physical Properties
  • Density: The density of Alloy 3003 is approximately 2.73 g/cm³, which is relatively low, making it a lightweight material.
  • Melting Point: It has a melting point range of 643 - 657 °C, which is suitable for various manufacturing processes.
  • Thermal Conductivity: The thermal conductivity is 155 - 168 W/(m·K) at 20 °C, indicating good heat transfer capabilities.
  • Electrical Conductivity: It has an electrical conductivity of 30 - 35% IACS (International Annealed Copper Standard), which is sufficient for many electrical applications.
• Corrosion Resistance
  • Alloy 3003 has excellent corrosion resistance. The aluminum - manganese alloy forms a thin, dense, and self - healing oxide layer on the surface, which protects the underlying metal from further corrosion. It can resist corrosion from water, atmospheric exposure, and many common chemicals, making it suitable for use in various outdoor and indoor applications.

Paint Coating Performance

 

Prepainted Finish

The prepainted finish on the 0.30mm thick Alloy 3003 H24 aluminum sheet offers several benefits. Firstly, it provides an additional layer of protection against corrosion. The paint coating acts as a barrier, preventing direct contact between the aluminum surface and the surrounding environment, thus extending the lifespan of the capacitor components made from this sheet. Secondly, the prepainted finish can enhance the aesthetic appearance of the electrolytic capacitors, which may be important for certain applications where the visual aspect of the product matters. Additionally, the paint can also have specific electrical insulation properties that contribute to the overall performance and safety of the electrolytic capacitors.


 

Use Application

Application in Electrolytic Capacitor Production

In the production of electrolytic capacitors, the 0.30mm thick Alloy 3003 H24 prepainted aluminum sheet is typically used for various components such as capacitor casings, electrodes, or other structural parts. Its consistent thickness and excellent material properties ensure the precision and quality of these components. The formability of the sheet allows for the creation of complex shapes that are necessary for the proper functioning of electrolytic capacitors. The combination of corrosion resistance, strength, and the protective prepainted layer helps to improve the reliability and performance of the capacitors, making them suitable for a wide range of applications in electronics, including power supplies, consumer electronics, and industrial equipment.

 

In conclusion, the 0.30mm thick Alloy 3003 H24 prepainted aluminum sheet is a vital material in the electrolytic capacitor production process. Its unique combination of alloy properties, temper, and prepainted finish makes it an optimal choice for manufacturing high-quality and reliable electrolytic capacitor components.
