Theknoloji ea bohlokoa ea Beryllium Copper (Phekolo ea mocheso)
Phekolo ea mocheso ke mokhoa oa bohlokoa ka ho fetisisa bakeng sa tsamaiso ena ea alloy. Le hoja li-alloys tsohle tsa koporo li thatafalloa ke ho sebetsa ha serame, koporo ea beryllium e ikhetha ka ho thatafalloa ke phekolo e bonolo ea mocheso o tlaase oa mocheso. E akarelletsa mehato e 'meli ea motheo. Ea pele e bitsoa annealing ea tharollo 'me ea bobeli, pula kapa ho thatafatsa lilemo.
