The aluminum slugs for electronic capacitors are usually used for the outer shell or electrode part of the capacitor. Aluminum materials are suitable for large-scale production due to their good conductivity, light weight and corrosion resistance, and are widely used in electronic components. 1070 aluminum slugs is a high-purity aluminum material with an aluminum content of more than 99.7%. Due to its excellent conductivity, corrosion resistance and good formability, it is widely used in the manufacture of electronic components, including the outer shell of capacitors.
- Material properties
– Purity requirements: The aluminum slugs for capacitor shells are usually made of high-purity aluminum (such as 1070, 1060 and other grades), and the purity is generally required to be more than 99.7% to ensure good conductivity and corrosion resistance.
– Mechanical properties: The aluminum slugs need to have a certain strength and toughness to withstand subsequent processing (such as stamping, stretching) and mechanical stress during the use of capacitors.
– Surface treatment: Anodizing or other surface treatment is usually required to improve corrosion resistance and insulation properties.
- Processing technology
– Stamping: The aluminum slugs is made into the capacitor shell by stamping process, which requires the material to have good stamping performance to avoid cracking or deformation.
– Dimensional accuracy: The shell size of the capacitor needs to be precisely controlled to ensure the matching degree with the internal components (such as electrodes, electrolyte).
– Surface finish: The inner surface of the shell needs to be smooth to avoid adverse effects on the performance of the capacitor.
- Application scenarios
– Aluminum electrolytic capacitors: Aluminum slugs 1070 are often used to make the shell of aluminum electrolytic capacitors. This type of capacitor is widely used in power filtering, coupling, bypass and other circuits.
– Power capacitors: In high-voltage power capacitors, aluminum shells are also often used because of their light weight and good heat dissipation.
In short, 1070 aluminum slugs for electronic capacitors are ideal for making capacitor shells due to their excellent physical and chemical properties.
