Metal Polishing Compound Bar

Polishing compound bars are used in the aluminium sector to remove scratches and imperfections and restore shine to aluminium surfaces. Specifically, a brown Tripoli bar is often used for the initial cutting and buffing of aluminium, removing 400-600 grit scratches. Green rouge bars are then used for a finer finish, creating a rich luster and mirrorlike shine.

Here's a more detailed breakdown:

Brown Tripoli:

This bar is commonly used as the first step in polishing aluminium. It is effective at removing scratches and imperfections from the surface, especially those in the 400-600 grit range, according to Red Label Abrasives.

Green Rouge:

After using the brown Tripoli bar, a green rouge bar is often employed to further refine the surface and create a smoother, more polished appearance. This bar, containing chromium oxide, provides a richer, deeper luster.

Other Colors (e.g., blue, purple):

For a mirror-like finish, additional polishing steps using blue or purple rouge bars can be incorporated after the green rouge, says Red Label Abrasives.

Applications:

These compounds are used on various aluminium products, including automotive trim, cookware and other items requiring a polished finish.

Process:

The bars are applied to a buffing wheel, which is then used to polish the aluminium surface.
