、使用耐酸的钛材料制造，导电棒接触部分的挂钩是用好的紫铜做材料； 2 、能使电流自由通过，而不会因断面太小，电阻太大产生过热烧坏组件； 3 、其与零件接触面积小，接触部分不会产生局部过热而烧毁零件和组件； 4 、那些用通用挂具无法挂的零件，为了保证产品质量和提高生产效率，都可根据零件的外型和氧化部位来设计和制造挂具。 baikeviewinfo.catalist = baikeviewinfo.catalist.concat([{"title":"\u4ecb\u7ecd","charnum":77,"screennum":0,"containpic":0,"containvideo":0,"level":1,"index":1,"display":true,"ele":"1"},{"title":"\u7279\u70b9","charnum":244,"screennum":0,"containpic":0,"containvideo":0,"level":1,"index":2,"display":true,"ele":"2"}]);
