Which material is the steel-cutting blade NOT made of?

The steel-cutting blade is primarily designed for durability and strength, which is why it is typically made from materials that can withstand high wear and resist deformation under stress, such as carbon steel, stainless steel, and tool steel.

Aluminum, on the other hand, is not a suitable material for steel-cutting blades due to its lower strength and hardness compared to the other materials. While aluminum is lightweight and has some benefits in other applications, it lacks the necessary properties to effectively cut through steel, making it unsuitable for this purpose. This distinction emphasizes the need for blades made from more robust materials that can handle the demands of cutting steel efficiently.
