SiC (Silicon Carbide) is the hardest and sharpest of the minerals used in abrasives. Thanks to its hardness and very sharp shape, this abrasive is ideal for multiple applications that do not require great pressure when cutting. Its grains are friable and, when broken, they continually expose new cutting edges that allow rapid removal of the material. It is more aggressive than Alox but wears out more quickly.

Lightweight and flexible, A or B papers are mainly used for manual operations or to support delicate, fine-grained operations. They can be prepared for wet work.
C or D papers, medium and light respectively, are used when some flexibility and resistance are required. Stronger and less flexible than the A and B papers, this type of support is still chosen for manual work (dry or wet), allowing it to be used on many sanding machines, even with medium pressure.

The grits presented are the most common for the operations in question, but they do not exhaust all available alternatives. We will be happy to help you find the best solution for your case.

The measures indicated are merely examples and are common in industry.
