Application description:
Widely used in precision machining (shafts, pins, bushings, gears), aerospace components, automotive parts (pistons, suspension links), marine fittings, electrical connectors, fasteners (bolts, rivets), and structural frameworks. Also suitable for handrails, furniture legs, sporting goods (bicycle crank arms, climbing anchors), and general engineering prototypes. The combination of lightweight, strength, and excellent machinability makes it ideal for both industrial and consumer products.
Production description
Aluminum billet is heated and extruded or cold drawn through a die to achieve the desired shape (round, square, hexagonal, etc.). The bar is then stretched and straightened, heat treated (T4, T5, T6, etc.) to enhance mechanical properties, and cut to length. Optional surface finishing includes turning, polishing, or anodizing. Finished bars are inspected for dimensional accuracy and surface quality.
Shipping Packaging
For export, aluminum bars are bundled with interleaved paper or plastic separators, wrapped with VCI paper and moisture-proof polyethylene, packed on ISPM-15 pallets, secured with steel straps, and fitted with edge protectors. Labels include alloy, shape, dimensions, length, and heat number for safe sea freight.
