3003 Aluminum vs. Borosilicate Glass
3003 aluminum and borosilicate glass belong to fundamentally different material chemistries. 3003 aluminum is a metal, while borosilicate glass is a ceramic material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 15 material properties with values for both materials. Properties with values for just one material (30, in this case) are not shown.
For each property being compared, the top bar is 3003 aluminum and the bottom bar is borosilicate glass.
