2024 Aluminum vs. Hexagonal Boron Nitride
2024 aluminum and hexagonal boron nitride belong to fundamentally different material chemistries. 2024 aluminum is a metal, while hexagonal boron nitride is a ceramic material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 10 material properties with values for both materials. Properties with values for just one material (29, in this case) are not shown.
For each property being compared, the top bar is 2024 aluminum and the bottom bar is hexagonal boron nitride.
