Bare aluminum foil—often referred to as “plain foil”—is a foundational aluminum product created through the melting, casting, and cold-rolling of aluminum ingots. It undergoes no further processing, such as coating, lamination, printing, or embossing. Retaining its original silvery-white metallic surface and inherent material properties, it serves as a versatile substrate for various types of deep-processed aluminum foil […]
A plain aluminum foil jumbo roll—also referred to as a master coil or simply an “aluminum foil jumbo roll”—is a wide-width coil of aluminum foil produced through processes including melting and casting, hot rolling, cold rolling, foil rolling and annealing. Plain aluminium foil is typically supplied as an industrial raw material to facilities specializing in lamination, […]
Bare aluminum foil serves as the essential substrate for various functional coatings. Its surface cleanliness, thickness uniformity, and flatness directly determine coating adhesion, application precision, and the yield rate of the final product. Haomei Aluminum optimizes bare aluminium foil properties specifically for mainstream coating processes—such as roll coating, rotogravure, and extrusion coating. Our bare aluminium foil […]
8021 aluminum foil serves as the essential barrier layer in the aluminum-plastic films used for soft-pack lithium-ion batteries. It plays a critical role in blocking moisture and oxygen, preventing electrolyte leakage, and enhancing the structural integrity of the packaging—factors that directly determine a battery’s cycle life, safety, and reliability. Haomei Aluminum has specifically optimized 8021 […]
8011 H18 aluminum foil is a widely used material for air filter separators, primarily serving HEPA high-efficiency filters, sub-HEPA filters, cleanroom filters, HVAC filters, and certain industrial dust collection systems. Its main function is to maintain stable spacing between pleated glass fiber filter media, ensuring uniform airflow through the filter element while supporting the pleats […]
Fins are critical thin-walled components responsible for heat exchange in air conditioners, condensers, and evaporators. As refrigerant flows through the tubes and air passes through the gaps between the fins, heat transfer occurs at the interface where the fins contact the copper tubes. The thermal conductivity, formability (specifically stamping performance), and corrosion resistance of the […]
Electronic aluminum foil serves as the core electrode material for aluminum electrolytic capacitors, performing the critical functions of forming the dielectric oxide layer and providing the necessary electrode surface area. Based on their roles within the capacitor, electronic aluminum foil for capacitor are categorized into two main types: anode foil and cathode foil. Anode foil undergoes electrochemical etching […]
Among electronic grade aluminum foil products, capacitor aluminum foil is one of the most demanding segments of the aluminum foil industry regarding raw material purity and surface consistency. Processes such as anodic etching and formation (for anodes) and the creation of oxide films (for cathodes) in electrolytic capacitors rely directly on the surface purity and […]
