What material is more efficient to clean or polish the surface of metal parts?

Here we tell you some details and differences about the abrasives known as "Steel Abrasive" and "Silica Sand"!

The surface treatment of metal parts is essential for future conditioning or work in the workshop. And the abrasives mentioned above can help you give them that perfect finish you need, but which of the two is better to optimize efficiency, speed, quality and cost?

To make the best decision, you must take into account elements such as size, shape, hardness and fragility.

For example, starting with the "Silica Sand", which due to its extreme fragility and thanks to the fact that it is projected by high production equipment, can only be used once since up to 80% of the material turns into dust.

Shot blasting, also known as abrasive blasting, is even known by some as "sandblasting" by its English term, although the latter concept refers exclusively to blasting with silica sand. It is a process where an abrasive material is propelled by means of air, water or centrifugal force against a surface.

This method is used to clean, strengthen or prepare surfaces.

There are many variants in the procedure to throw the abrasive medium but the most common is to do it through a machine with wheels, which drive the abrasive against the target, that

To understand the how well, we need to understand well what is sand blast or sandblasting? The definition of this word is understood as “sand under pressure”; however, numerous abrasives in addition to sand can be used in this operation to clean, polish or remove materials and residues from different surfaces.

In areas of abrasives, we have 2 types commonly used:

ARTIFICIAL ABRASIVES

• Aluminum oxide
• Steel shot
• Silicium carbide
• Sodium bicarbonate
• Cut wire
• Garnet
• Copper slag
• Glass pearl
• Plastic abrasive

NATURAL ABASIVES

• Silica sand
• Diamonds
• Quartz
• Corundum

To sandblast, we use compressed air which propels the abrasives at
