AA1050 H18 0.4MM Prepainted Aluminium Coil for Capacitor Shell

AA1050 H18 0.4MM Prepainted Aluminium Coil for Capacitor Shell

 The AA1050 H18 0.4MM Prepainted Aluminium Coil is a high-performance material specifically developed to meet the strict standards of capacitor shell manufacturing. It is made from AA1050 aluminum alloy—a high-purity grade with an aluminum content of no less than 99.5%—which undergoes precision rolling to a thickness of 0.4mm and is processed to achieve the H18 temper (full strain-hardened, offering high strength). Its surface is covered with a high-quality, insulation-enhanced pre-paint layer, designed to adapt to the internal environment of capacitors while providing reliable protection—making it a key material for high-quality capacitor shells.

Product Parameters

Application Scenarios

• Power Capacitors: Shells for power factor correction capacitors, filter capacitors, and harmonic suppression capacitors used in power systems. The material’s high strength and insulation ensure the shell can withstand the pressure and electrical environment inside the capacitor, guaranteeing stable operation of power equipment.
• Electronic Capacitors: Shells for aluminum electrolytic capacitors, film capacitors, and ceramic capacitors used in electronic devices such as computers, televisions, and mobile phone chargers. Its thin thickness (0.4mm) helps reduce the overall size of the capacitor, meeting the miniaturization demand of electronic products.
• Industrial Capacitors: Shells for capacitors used in industrial equipment like frequency converters, welding machines, and motor drives. The corrosion-resistant pre-paint layer protects the shell from the influence of industrial dust, moisture, and chemical substances, extending the service life of the capacitor.
• Automotive Capacitors: Shells for capacitors used in automotive electronic systems, such as engine control units, in-vehicle infotainment systems, and electric vehicle power modules. The material’s lightweight and high-temperature resistance (adaptable to the high-temperature environment in the engine compartment) make it suitable for automotive applications.
