Which material is used for a saw that cuts through masonry?

The correct choice is diamond, which is known for its exceptional hardness and durability, making it the ideal material for cutting through tough surfaces like masonry. Diamond blades are widely used in saws, as they maintain sharpness over extended periods and can efficiently cut through concrete, brick, and stone materials without excessive wear.

Silicon carbide is also a hard material used in various cutting applications, but it does not offer the same level of performance as diamond when it comes to cutting through masonry. Steel is a common material for blades, but its hardness is significantly lower than that of diamond, rendering it less effective for masonry applications. Aluminum, while lightweight and useful in other contexts, lacks the necessary hardness and strength to effectively cut through masonry. Therefore, diamond emerges as the standout choice for precise and effective cutting in masonry work.
