There are also several companies in Russia for which tungsten business is not an essential activity. Here is a list of them:"Chelyabinsky electrometallurgical plant" at Ural (Ferro-tungsten and special steels),"Electric steel" in Moscow region (tungsten powder and cemented carbides), JSC "Polema" in Tula (tungsten powder, covering and bars) and JSC "Sandvik-MKTC" in Moscow (hard metal plates and cutting tools).

俄罗斯也有一些公司并不以钨初级产品为主营业务，如位于乌拉尔地区的切利尔宾斯基电冶厂（Chelyabinsky electrometallurgical plant），以钨铁和特种钢为主要产品；位于莫斯科地区的电炉炼钢公司以钨粉和硬质合金为主要产品；位于图拉地区的波勒玛公司，以钨粉、钨涂层及钨条为主要产品；位于莫斯科的山特维克-麦克提克公司（Sandvik-MKTC）以硬质合金板材和切割刀具为主要产品。

Therefore, the carbide drilling tools is the center of the modern drill steel and drilling tools industry, is becoming the key industry for the new generation of"resources＆ hi-tech ＆export-oriented" national industry and permanent industry. Just as OPEC play a leading role in world oil market, so we could play a leading role in world tungsten market after entering WTO, will open a whole new era---to accomplish the lofty ideal of"promote tungsten industry""recover the old things" for the peace, development and progress of the people.

因此，现代化的硬质合金钎具工业，不但对我国采掘工业和国民经济持续健康发展具有重要意义，它作为我国民族工业中新兴的&资源-高科技-外向型&支柱产业之一，在加入WTO之后，有可能发展成为如同欧佩克组织组织主导世界石油市场一样主导世界钨品市场和全球硬质合金钎具市场，从而为中华凿岩技术光复旧物，为实现国家&振兴钨业&的战略目标，并进而对人类和平、发展与进步的事业作出当代中国人的新贡献。
