Uchungechunge lwe-5 / 6 / 7 luya kusetyenziswa kwi-CNC processing, ngokweempawu zechungechunge lwe-alloy.

Ii-alloys ze-5 ze-series ziyi-5052 kunye ne-5083, kunye neenzuzo zoxinzelelo oluphantsi lwangaphakathi kunye nokuguquguquka kwemilo ephantsi.

Ii-alloys ze-6 ze-series ziyi-6061,6063 kunye ne-6082, eyona nto ibiza kakhulu, ubunzima obuphezulu kune-5 series kunye noxinzelelo lwangaphakathi oluphantsi kune-7 series.

I-7 ye-alloy ye-series ikakhulu yi-7075, ebonakaliswe ngobulukhuni obuphezulu, kodwa uxinzelelo olukhulu lwangaphakathi kunye nobunzima obukhulu ekusebenzeni.
