If nothing else works, anyone with a decent drill should be able to drill it out. Can’t picture the axle being anything but aluminum. In lack of drill, put a hack saw to the area between the end cap of hub and inside Of fork leg on the threaded side. Then hammer the axle out. Axles usually get stuck due to bonding between inside of hub and axle, not threads in fork.
