The main difference between 1100 H14 aluminum and 1100-O aluminum lies in their processing methods, which result in different mechanical properties. Both alloys have the same chemical composition, but different heat treatment and work hardening processes make them suitable for different applications.

1100-H14: Thermal Shock Resistance: 1100-H14 has a thermal shock resistance rating of 5.5, which is better than the 3.9 rating of 1100-O. This makes 1100-H14 better suited for environments with rapid temperature changes, such as in aerospace or certain industrial applications.
1100-O: Less Resistance to Thermal Shock: 1100-O, while still having good thermal properties, is less resistant to thermal shock compared to the H14 variant. This could be a consideration in applications where the material is exposed to rapid temperature changes.
