Aluminum Pipe with Irregular-shaped Cross Section
Different cross-sectional shapes are achieved in a single pipe while maintaining required pipe strength
The aluminum pipe used in four-wheel steering systems proposed by UACJ Extrusion Corporation is a patented one-piece beam that does not have joints, using a unique technology to create varied cross-sections, outer diameters, and wall thicknesses in the longitudinal direction from a single pipe. The beam is formed with high dimensional accuracy and shape flexibility, allowing various methods other than welding to be used for mounting of brackets/stays. In addition, it can be used for non-automotive applications.
- A single pipe with different cross sections, outer diameters, and wall thicknesses in the longitudinal direction.
- Increases flexibility in the way brackets/stays are installed.
- Materials can be selected according to the requirements of stiffness and welded joint strength.
- Process reduction (no welding/straightening) is possible by adopting an integrated variable stepped pipe that has a round cross-section at one end, shrinking its diameter toward the other end at which the cross-section is a polygon.
- By reducing the wall thickness at the same time as shrinking the diameter and varying cross-section shapes, it is possible to reduce the weight while maintaining strength in the necessary parts. There are cases in which the weight was reduced to half compared with conventional steel products.
- By providing flat and curved sections in each cross section, it is possible to simplify and optimize the mounting method of parts.
- Materials including 5000 and 6000 series alloys can be selected according to the requirements of stiffness and welded joint strength.
- Upon request, we can provide products including secondary processing, surface processing, and parts bonding, contributing to the reduction of procurement man-hours.
