Easy-open lid aluminum alloy 3004/3104/5182
The convenient-to-open (Easy Open) lid construction typically employs 5182 aluminum alloy, renowned for its exceptional formability, robust strength, and impeccable sealing capabilities, making it an ideal choice for can lid manufacturing. Moreover, 3104/3004 aluminum alloys are employed as alternative materials, particularly when projects necessitate superior deep drawing characteristics and thinning stretchability to facilitate lightweight designs. The employment of these aluminum alloy variants is strategically aimed at fulfilling the stringent criteria of can lid materials, emphasizing processing efficiency, strength, and sealing integrity. The 3004 aluminum alloy belongs to the Al-Mn series, boasting superior strength over the 3003 aluminum plate, coupled with excellent formability, solubility, and corrosion resistance. Its primary applications encompass components that necessitate a higher strength threshold than the 3003 alloy, encompassing chemical products, storage systems, thin plate fabrication elements, architectural baffles, cable trays, sewage piping, and diverse lighting fixtures. Requirements for Easy-open can lid material Can lids are usually made of metal, usually aluminum. The requirements for can lid materials mainly include the following points: ◆Food safety: Can lids must be made of materials that meet food safety standards to ensure that they will not affect the quality and safety of canned food. ◆Sealing: The lid must have good...
