Product Description
Main features and application scope of 2A16 aluminum rod: This is a kind of heat-resistant hard aluminum, which is characterized by: the strength is not too high at normal temperature, but it has high creep strength at high temperature, and the alloy has Strong plasticity, no extrusion effect, can handle strengthening, spot welding, seam welding, good welding performance, less tendency to form cracks, good air tightness of welds, low corrosion stability of welds, corrosion of aluminum-clad sheets The stability is still good, and the corrosion resistance of the extruded semi-finished product is not high. In order to prevent corrosion, anodizing treatment or painting should be used for protection: the machinability is still good.
Uses It is mainly used for parts that work at 250-350 °C, such as bearings to compressor blades, discs, and plates for welding parts that work at room temperature and high temperature, such as containers, airtight warehouses, etc.
The 2024 aluminum rod is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is relatively reasonable and its comprehensive performance is better. It is the largest amount of duralumin. 2024 aluminum bar belongs to high-strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity in quenched and just-quenched states, and spot welding is good. When gas welding is used, it has a tendency to form intergranular cracks. The cutting performance is still good, and the machinability after annealing is low: the corrosion resistance is not high, and anodizing treatment and painting methods are often used or the surface is coated with aluminum layer to improve its corrosion resistance.
