C17200 Copper (CDA 172)

C17200 imadziwikanso kuti Aloyi 25 ndipo ndiyomwe imagwiritsidwa ntchito kwambiri ndi beryllium copper alloy ndipo imadziwika chifukwa chowonetsa mphamvu komanso kuuma kwambiri poyerekeza ndi zida zamkuwa zamalonda. Kulimba kwake ndi kulimba kwake kumafanana ndi chitsulo. C17200 copper yokhazikika yolimba komanso yolimba ya Rockwell mu msinkhu wapamwamba kwambiri ili mu 200 ksi range ndi RC 45 motsatira (electrical conductivity 22% IACS osachepera).
