Features of 3003 aluminum bar rod
Good corrosion resistance: 3003 aluminum bars contain about 1.2% copper, which can improve the corrosion resistance of the material, especially in acidic environments.
Good formability: 3003 aluminum bar has excellent formability and can be formed by cold working and hot working methods, such as deep drawing, drawing, die casting, etc.
Good weldability: 3003 aluminum rods can be welded by various common welding methods, such as argon arc welding, arc welding, oxyacetylene welding, etc.
Good processability: 3003 aluminum bars can be processed by conventional machining methods, such as milling, drilling, turning, etc.
Lightweight and high-strength: 3003 aluminum rod is a light-weight and high-strength material with a density of about 2.73 g/cm³, which is about 1/3 lighter than ordinary steel, but its strength is higher than ordinary steel.
Wide range of applications: due to its good corrosion resistance, formability and processing properties, 3003 aluminum bars are widely used in the manufacturing of various parts and components in the manufacturing industry, such as manufacturing automobiles, aerospace, construction, electronics, home furnishing and other fields parts.
Classification and application of 3003 aluminum bar
3003 aluminum square bar generally refers to an aluminum rod with a square cross-section with sharp edges and corners. It has a wide range of uses and can be used to make various structural and mechanical parts, such as manufacturing aircraft parts.
3003 aluminum round bar refers to an aluminum bar with a round cross section, which is often used to make bearings, bolts, fasteners, nuts, gears, flanges, valves, electrical accessories, etc. on aircraft.
3003 aluminum flat bar refers to an aluminum rod with a rectangular or oval cross-section. Its main purpose is to manufacture various mechanical parts and structural parts.
3003 fine-drawn aluminum bar is a high-purity, high-precision aluminum rod with a high smooth appearance, no scale on the surface, and a dense and uniform internal structure. Used in aerospace equipment and equipment.
3003 H12 aluminum bar is easier to bend and deep draw to form and retains its overall shape and dimensions. Therefore, 3003 H12 aluminum rods are often used to make stretched formed parts, sheets, shells, etc.
3003 H14 aluminum bar has high strength and excellent corrosion resistance, and can operate stably in strong acid and strong alkali environment. Therefore, 3003 H14 aluminum rods are often used to make food packaging, air-conditioning heat exchangers, chemical devices, and structural parts in seawater environments.
3003 H16 aluminum rod has higher strength and better tensile properties, able to withstand greater loads. Therefore, 3003 H16 aluminum rods are often used to make structural parts, aerospace parts, etc.
3003 H18 aluminum rod is harder and tougher than other states, and has good processing properties, so it is suitable for applications that require strength and wear resistance, such as aircraft hydraulic piping.
