Which product is commonly made using sintering?

Sintering is a process commonly used in powder metallurgy, where fine particles of a material are heated below their melting point to bond them together. This technique is particularly effective for producing cutting tool tips, which require a hard and durable material to withstand high levels of wear and heat during cutting operations. Cutting tool tips are often made from materials such as tungsten carbide or ceramic compounds, which are compacted and sintered to achieve the desired density and mechanical properties.

In contrast, other options are generally manufactured using different methods. For instance, while copper wires involve processes like drawing or rolling, steel beams are typically formed through casting or forging methods. Plastic components, on the other hand, are produced mainly through injection molding or extrusion rather than sintering. Therefore, the correct choice highlights the specific application of the sintering process.
