Sumitomo Electric Industries has developed a high-strength magnesium alloy pipe that is 20 percent stronger than extruded magnesium alloy bars.
The pipe’s strength and light weight make it suitable for use in a wide range of applications: automotive and electronic parts, medical and welfare apparatus such as wheelchairs and stretchers, and leisure and sporting goods such as bicycles and tennis rackets.
For the time being, SEI expects demand for the magnesium alloy pipe for use as a substitute for high value-added materials that use carbon fiber reinforced plastic. SEI will continue to reduce costs and improve corrosion resistance and seek new applications.
Magnesium is one-quarter the density of iron and about two-thirds the density of aluminum.
