Aluminum rod is a kind of non-ferrous metal rod, which refers to a metal rod-shaped material that is made of pure aluminum or aluminum alloy by kneading and processing into a hollow along its longitudinal full length. Available with one or more closed through holes, with uniform wall thickness and cross-section, delivered in straight or in rolls. Widely used in cars, ships, electrical appliances, agriculture, electromechanical, household and other occupations.
Aluminum rods are mainly divided into the following categories, characteristics and advantages according to their shapes: square rods, round rods, patterned rods, special-shaped rods, and universal aluminum rods. According to the kneading method: seamless aluminum rods and general kneading rods are divided according to accuracy: general aluminum rods and fine aluminum rods, among which fine aluminum rods generally need to be reprocessed after kneading, such as cold drawing and fine drawing, rolling.
According to thickness: general aluminum rod and thin-walled aluminum rod Properties: corrosion resistance, light weight. Characteristics of aluminum rods: The classification, characteristics and advantages of aluminum rods are high-strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity under annealing, just quenching and thermal conditions, and good spot welding.
Aluminum rods tend to form intergranular cracks when gas welding and argon arc welding are used; the machinability of aluminum rods after quenching and cold work hardening is still good, but not good when annealed. The corrosion resistance is not high, and anodizing treatment and painting methods are often used or an aluminum layer is added to the surface to improve the corrosion resistance. It can also be used as a mold material.
