Aluminum slugs are a common type of aluminum blank used to make cigarette lighter shells. They are typically made from round, sheet-like metal blanks of pure aluminum or aluminum alloys, which are then stamped and formed into lighter casings.
Aluminum slugs for lighter shells usually use high-purity aluminum, such as 1060 or 1070 aluminum slugs. These aluminum materials have good ductility and corrosion resistance, are easy to process and shape, and ensure the durability of the lighter casing.
Specifications of aluminum slugs for cigarette lighter shells:
The diameter and thickness of the aluminum slugs depend on the design requirements of the lighter casing. Common diameter specifications include 13.15mm, 15.6mm, and 18.6mm, with a thickness generally around 4.1mm.
Characteristics of aluminum slugs for cigarette lighter shells:
– Lightweight:
The density of aluminum slugs is much lower than that of metals such as copper and steel, making the overall weight of the lighter lighter, easier to carry and use.
– Corrosion resistance:
Aluminum alloys form a dense oxide film on their surface, providing excellent corrosion resistance and protecting against environmental influences, thus extending the lighter’s lifespan.
– Good machinability:
Aluminum slugs 1070 possess good plasticity and machinability, easily processed into various shapes and sizes of lighter casings through stamping, cutting, and drilling.
– Thermal conductivity:
Aluminum has good thermal conductivity, aiding in heat dissipation and reducing the lighter’s temperature during use.
– Moderate strength:
Aluminum alloys possess sufficient strength to meet the load-bearing and protective requirements of the lighter casing without being excessively heavy.
Processing of aluminum slugs into cigarette lighter shells:
Stamping: Aluminum slugs are placed in a stamping die, and pressure is applied using a stamping press to form the initial shape of the lighter casing.
Cutting and drilling: The stamped casing is cut and drilled to obtain precise dimensions and shapes, and ventilation holes, mounting holes, etc., are created.
Surface treatment: To improve the aesthetics and durability of the lighter casing, the formed aluminum casing typically undergoes surface treatment. Common methods include anodizing, sandblasting, painting, or powder coating. Anodizing forms a wear-resistant and corrosion-resistant protective film on the surface; sandblasting gives the surface a matte texture and makes it less prone to fingerprints; painting or powder coating allows for various colors to be applied to the casing.
Applications of aluminum slugs for cigarette lighter shells:
Disposable lighters: Many disposable lighters use aluminum alloy casings due to their low cost, high production efficiency, and ability to meet basic usage needs.
High end lighters: Some high end lighters also use aluminum alloy casings, but they typically employ higher-quality aluminum alloy materials and more refined processing techniques and surface treatments to enhance product quality and prestige.
