Summary:PURPOSE:To obtain novel tube material effective to a decoration by obtaining a round stock in which the outer circumferential surface of an inner material made of tubular material is coated with an outer material from the different material, squeezing the round stock to obtain a flat stock, grinding its surface, thereafter, rounding the flat stock in the shape of a tube. CONSTITUTION:The tubular inner material 1 made of gold is inserted into the inner diameter hole of the tubular outer material 2 made of platinum and then a round stock 3 is obtained by drawing the resultant material. Then, the round stock 3 is squeezed to obtain a flat stock 4. Thereafter, the upper surface of the flat stock 4 is ground to expose a part 5 of the inner material 1. Then, the flat stock 4 is rounded in tubular shape as this inner material surface is exposed on the outer circumferential surface, consequently, a spirally twisted tube stock 6 is obtained. Sometimes, silver, platinum, iridium, etc., are used as the inner material 1 and gold, silver, iridium, etc., are used as the outer material.
