PURPOSE: To provide the Ti material as an ornaments member having the good chasing property to allow, for example, rapid and easy working by specifying an oxygen content to a specific value or blow to increase the purity of the material.
CONSTITUTION: The above mentioned Ti material has ≤600ppm oxygen content and further preferably ≤100ppm and consists of the balance Ti and incidental impurities. The incidental impurities include nitrogen, carbon, Fe, Ni, Cr, Al, K, Na, etc., and may be incorporated into the material to the extent of not disturbing the function of the desired object. The oxygen improves the chasing property ('ease of carving') with a decrease in the content thereof in the Ti material and the upper limit thereof is 600ppm. The carving of characters and ornamental patterns is extremely easy according to the Ti material having such chasing property. The excellent member for ornamentation having the ornamental characteristic in combination is obtd. from a chemically treated layer having wear resistance.
