Although difficult to form, tungsten is used in various shapes for different applications. We developed tungsten ribbons (flat wires) in which we can precisely control the ratio between the width and the thickness. Tungsten ribbon is used widely in medical and environmental applications because it is highly visible on X-ray images, and has high strength. We evaluated the visibility on X-ray and the mechanical properties of braided tubes made from tungsten ribbon or wire. We compared these properties with those of braided tubes made from stainless steel. We confirmed that tungsten ribbon has high visibility on X-ray images owing to the increased surface area increases. Braided tubes made from Tungsten are more resistant to deformation than those made from stainless steel.
