Aluminum Parts FAQ
What aluminum tolerance do you hold on production families?
+/-0.01 mm general and +/-0.002 mm on datum features are routine on repeat families; the CMM report groups features by datum so incoming inspection can verify quickly.
Do you machine cast plate like MIC-6 alongside wrought grades?
Yes, MIC-6 cast plate for fixture baseplates is stocked alongside 6061/7075/5052; cast plate gives flat, stress-stable bases without heat treatment.
