Porosity is a critical concept in materials science, especially when it comes to high-performance materials like tungsten carbide (WC) used in industrial tools. Though often overlooked, porosity plays a significant role in determining the mechanical strength, wear resistance, and overall reliability of carbide tools. This article breaks down what porosity is, how it forms, why it matters, and how manufacturers manage it. What Is Porosity? Porosity refers to the presence of tiny voids or pores within a material. These voids may be microscopic or visible to the naked eye, and they result from incomplete densification during the manufacturing process. In cemented carbides, porosity is the space that remains unfilled
