Description
Brass, fundamentally a copper alloy blended with zinc, boasts both strength and malleability, rendering it a popular selection for a wide array of uses. By adjusting the zinc content, a diverse range of properties can be achieved, encompassing varying degrees of resistance to corrosion, ductility, and appropriateness for machining.
