Quelle est la différence entre le carbure de silicium F Grit et P Grit?

F grit and P grit are two designations for the size and shape of silicon carbide abrasive particles, used in grinding and sanding applications. The key difference lies in their intended use:

F Grit VS P Grit

• F grit (FEPA-F): Stands for « Federation of European des Fabricants de Produits Abrasifs » (European Federation of Abrasive Products Manufacturers). This designation is typically used for bonded abrasive tools like grinding wheels, sharpening stones, and whetstones. F grit particles are crushed and tend to be more rounded in shape.
• P grit (FEPA-P): This designation is used for coated abrasives like sandpaper, sanding discs, and belts. P grit particles undergo a different milling process, resulting in a more elongated or columnar shape. This shape allows the particles to fracture more easily, creating new cutting edges during use.

Here’s a table summarizing the key differences:

In essence, F grit is designed for heavy-duty material removal due to its more robust particles, while P grit is better suited for finer finishing due to its sharper and self-fracturing nature.
