VT machining offers CNC Surface Grinding for 1100 Aluminum (UNS A91100 / EN AW-1200), typically supplied O / H14. Small Cu addition gives slightly more strength than 1050 while keeping formability.
CNC Surface Grinding Notes for 1100 Aluminum
Soft 1100 Aluminum can load conventional wheels, so we use open-structure or silicon-carbide wheels and plenty of coolant.
