The invention not only relates to a general method for making rings, but also relates to a ring and a process for making rings with
tantalum as raw materials for the first time.
Rings are traditionally made from gold, silver, platinum and other softer materials, because these metals are very plastic and easy to pour, forge or mold. But these materials are also vulnerable to wear, scratches and other damage, reducing their life and appearance value. Tantalum is a metal that, once formed, is very hard. Because of this, it is difficult to shape, requiring special processing procedures and grinding tools, so as to change their configuration and appearance. We found that tantalum can be used in the field of jewelry in the sintering process of powder metallurgy. In addition, the material, if used in the ring, can protect the precious metals and precious stones that are embedded in the ring.
