Abstract

본 발명은 손목시계용 외장부품에서 유해 중금속 함유에 의한 피부 알레르기 발생을 억제하고 내식성 및 경도를 향상시킨 초경합금에 관한 것으로 TiC, TiN중 1종 또는 그 혼합이 1~40중량%, NbC, TaC중 1종 또는 그 혼합이 0.1~5.0중량%, Co, Ni중 1종 또는 그 혼합이 0.05~1.0중량% 이고, 나머지는 불가피한 불순물과 WC로 조성됨을 특징으로 하는 손목시계용 초경합금에 관한 기술이다.The present invention relates to a cemented carbide alloy that suppresses the occurrence of skin allergies due to the inclusion of harmful heavy metals and improves the corrosion resistance and hardness in the exterior parts for wristwatches. One or a mixture thereof is 0.1 to 5.0% by weight, Co or Ni, one or a mixture of 0.05 to 1.0% by weight, the remainder is a technique related to cemented carbide for wrist watches, characterized in that the composition is composed of inevitable impurities and WC.
