  电镀等产业方面. 
                
  硒:硒是玄色或深灰色玻璃状无定型锭块(红硒与灰硒为硒的结晶变体,主成份稳定),属于稀散元素,也称半金属.硒的熔点为220度,沸点为685度,密度为40808g/cm3,质脆,首要用于建造整流器,硒感光板,复印硒鼓,合金,珐琅和玻璃产业等方面.

    四、硬质合金 
  
  硬质合金俗称钨钢,是一种具备高硬度,杰出耐磨性,红硬性及必然的抗弯强度的东西资料.它的耐磨性比高速钢高10到20倍,红硬性也远胜于高速钢;是以硬质合金在古代化机器加工,煤油煤矿山采掘,金属型材加工,纺织,化工,仪器仪表部件及国防,兵器,兵工等范畴中获得了普遍的利用.别的:硬质合金的错误谬误是韧性低.是以,硬质合金刀片要镶装在钢制刀杆上(焊接或机器夹固),硬质合金模具则要装在钢制模套里.
