Alnoble®ZR

Outline

Alnoble® ZR is the product name for the highly corrosion resistant and highly strong aluminium foil newly developed by Toyo Aluminium. In addition to having a resistance to corrosion equivalent to that of high-purity aluminium foils, it also has an extremely high mechanical strength. Please consider the use of this material for food packaging applications that were difficult for conventional aluminium foils due to the resistance to corrosion from the contents packaged and as electrode materials for lithium-ion batteries, for which long-term stability is required.

Examples markets for aluminium foil where a high resistance to corrosion is demanded

Item Application
Electrolyte resistance Long-term durability is demanded for aluminium materials used for the lead terminals, current collector material and cladding materials on lithium-ion batteries, aluminium electrolyte capacitors and electric double-layer capacitors. Materials are required to have a high resistance to electrolytes and high strength to fulfill processing suitability requirements.
Chemical resistance When laminated materials made from aluminium foil are to be used for alkaline or acidic chemicals such as hair dyes, the durability of the material is determined by the corrosion resistance of the aluminium foil, even if it does not come into direct contact with the packaged contents.
Food resistance If aluminium foil comes into direct contact with highly corrosive foods, the aluminium may be dissolved and cause leakage of the contents or contamination with the dissolved materials. Highly food resistant aluminium foil is therefore required for these foods.
