Beschreibung
Zusammenfassung:	The invention relates to grade powders and sintered cemented carbide compositions. In one aspect, grade powder compositions are described herein comprising electrochemically processed sintered carbidescrap. In some embodiments, a grade powder composition comprises a reclaimed powder component in an amount of at least 75 weight percent of the grade powder composition, wherein the reclaimed carbidecomponent comprises electrochemically processed sintered carbide scrap. 本发明题为"等级粉末和烧结硬质碳化物组合物"。在个方面，本文描述了等级粉末组合物，所述等级粉末组合物包含电化学加工的烧结碳化物废料。在些实施方案中，等级粉末组合物包含所述等级粉末组合物的至少75重量％的量的再生粉末组分，其中所述再生碳化物组分包含电化学加工的烧结碳化物废料。
