All axles are made with aircraft quality 4130 steel, specifically made for Wheels Manufacturing.
Heat treated to increase strength, without making the axle brittle.
The threads are rolled, not cut, for the best thread strength and ease of assembly: the rolling of the thread removes no metal from the axle and preserves the grain of the material, maximising strength and leaving no sharp corner in the root of the thread.
