Is aluminum-magnesium alloy or pc good for luggage?

Both have their advantages and disadvantages.

1, pc material: mainstream material, characterized by light weight, good toughness, excellent color performance, even if it is recessed, it can be restored, not as brittle as abs, and it will not be easily broken even if it is hit, but there are fewer pure Pcs on the market, generally abs+pc.

2, aluminum-magnesium alloy material: high-grade is the most prominent, but the practicality is not strong, one is heavier than pc, and the worst thing is that the impact deformation is almost unrecoverable, but as long as it is not a great external force, it will hardly sink in, and its compression resistance is good.
