Aluminum Tube — Product Overview
The aluminum tube covered here is a seamless extruded pipe that is finished by cold drawing and produced in 7075 and 2024 grades. It is a straight hollow section intended for parts that need a low weight with dependable dimensional accuracy and a clean surface both inside and outside.
Grades and Material
7075 and 2024 sit in the high strength group of aluminum alloys, where the metal is alloyed with elements such as zinc, copper and magnesium to raise its mechanical properties above those of pure aluminum. 7075 is often selected where strength is the leading requirement, while 2024 is widely used where good fatigue behaviour and machinability matter. Both grades keep the characteristic light weight of aluminum.
Seamless Cold Drawing
A seamless tube starts as an extruded hollow section, so there is no longitudinal weld running along its length. Cold drawing then pulls the tube through a die at room temperature, which refines the wall, tightens the outside and inside diameters and improves the surface finish. The result is a tube with consistent wall thickness along its length and a smoother bore than an as-extruded section.
- Seamless body without a longitudinal weld seam
- Cold drawn for closer diameter and wall tolerance
- Smooth inside and outside surface
- Round and other section shapes available
Surface and Dimensions
The tube can be supplied in a natural mill finish, and the drawn surface accepts further machining, cutting, threading or bending as the end part requires. Outside diameter, wall thickness and cut length are the main dimensions a buyer specifies, and they can be held closely because of the drawing step.
Typical Applications
Tubing of this kind is used across industry where a light and strong hollow section is needed:
- Aircraft and aerospace structural parts
- Industrial machinery and equipment frames
- Hydraulic and pneumatic line components
- Precision machined bushes, spacers and sleeves
Customization Notes
Alloy grade, outside diameter, wall thickness, length and surface condition can be specified for the intended part. Because the tube is made to order, dimensions and tolerances are agreed around the drawing or specification the customer provides rather than a single stock size.
Summary
Made from 7075 and 2024 aluminum and finished by seamless cold drawing, this tube combines low weight, reliable tolerances and a smooth surface, which makes it a practical starting material for industrial, structural and machined hollow parts.
