A crystalline solid is harder to break, because the molecules in the solidare arranged in a defined order.
As far as I know, the only problem with using a crystalline solid is cost. The factory would need to melt the solid, and I assume all crystalline solids have a high melting point, so a factory would need to spend a lot of money on equipment capable of melting the solid, and the electricity required to melt the solid.
