Detailed introduction of aluminum bar

Return

Aluminum rod is a kind of non-ferrous metal rod, which refers to the metal rod-shaped material made of pure aluminum or aluminum alloy through kneading and processing to be hollow along its longitudinal full length. There can be one or more closed through holes with uniform wall thickness and cross-section, which can be delivered in a straight line or in a roll. It is widely used in cars, ships, electrical appliances, agriculture, electromechanical, household and other occupations.

Aluminum rods are mainly divided into the following types: square rods, round rods, patterned rods, special-shaped rods, and aluminum rods worldwide according to their classification, characteristics and advantages. According to the kneading method, seamless aluminum rods and general kneading rods are divided into general aluminum rods and fine aluminum rods according to the accuracy. In the meantime, fine aluminum rods generally need to be reworked after kneading, such as cold drawing, fine drawing and rolling.

Divided by thickness: General aluminum bar and thin-wall aluminum bar performance: 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, has medium plasticity in annealing, just quenching and thermal conditions, and has good spot welding.

When gas welding and argon arc welding are used, intergranular cracks tend to form in aluminum bars; The machinability of aluminum bar after quenching and cold work hardening is good, but it is not good when annealed. The corrosion resistance is not high, and anodic oxidation and painting methods are often used or aluminum coating is added on the surface to improve the corrosion resistance. It can also be used as mold data.
