Is aluminum a worthy material for a knife? - toyota1515 - 12-28-2017
Aluminum is a soft metal that can deform easily and has low plasticity and melting temperatures. While its malleability and light weight make it ideal for uses where weight restrictions are critical, such as aircraft, for uses where it it would be exposed to continued rough use or heat, it is not ideal. It also cannot hold an edge like steel, steel alloys and many ceramics can.
An aluminum knife blade is possible. However, it wouldn't be the "go to" choice for most knife wielders or users.

Aluminum can only be used for knife handle and not the blades due to it's soft/ductile nature. It will easily deform and may not cut through a piece. Steel does it better

Only as a wall decoration. The only advantages I could think of are that it wouldn’t stain, and it’d be really easy to get an edge on it.
But the edge would last all of 41 seconds of usage. Think of what your looking to use the knife for then look around for the best type for the job….made of some kind of steel.
