ANS:B - brass

Dezincification is a form of corrosion that specifically applies to brass. Brass is an alloy primarily composed of copper (Cu) and zinc (Zn). In dezincification, the zinc component of the brass alloy is selectively removed from the material, leaving behind a porous copper-rich structure. This process weakens the material and can lead to structural failure, especially in applications where the mechanical integrity of the brass component is crucial. Dezincification typically occurs in environments where the brass is exposed to certain aggressive agents, such as acidic or alkaline solutions, oxygen, and high temperatures. Common examples of dezincification include brass fittings in plumbing systems, where exposure to corrosive water or chemicals can accelerate the degradation of the material. It's worth noting that dezincification is a specific form of corrosion that targets brass alloys, whereas other materials like steel, stainless steel, and babbitt metal may experience different types of corrosion mechanisms under various environmental conditions.
