Topic tags/keywords: question sander sanding discs

I thought I found a pretty good deal on Abralon sanding discs . Well, the place I ordered from sent me some of the grits I ordered in Abralon discs, and some grits in SIA Air discs. I am not at all happy with the substitution without getting an okay from me, but now that I have them, I am curious if the SIA discs are an equal substitute.

The major difference is that Abralon is made with Silicon Carbide and SIA discs are made with Aluminum Oxide. According to Mirka, manufacturer of Abralon, “Aluminum Oxide grains plough into soft wood types” and “Silicon Carbide grains cut through hardwood.” In the microscopic picture the Silicone Carbide surface looks smoother.

SIA Air discs are distributed by Brunswick Bowling and the “experts” on the bowling forums swear by them, saying they last much longer than Abralon when used for polishing bowling balls. SIA discs can also be purchased from Grizzly, but Abralon is much more common on the other woodworking suppliers websites I visited.

Considering my skill level, this is unlikely to make much difference in my work, but I am curious anyway. What do you folks think? Would there be a detectable difference in the results between using Silicon Carbide or Aluminum Oxide? What are the plusses and minuses of using one or the other? Are Abralon and SIA close enough to considered the same even though they are composed of different materials, or is one significantly superior for woodworking?

I wonder if you made a really big Ort, could you use it for a boat?
Then we could all be in it together.
BarbS might know.

Well, guys, nice to know I am not the only one in the boat! Sanding and finishing is so important to our craft, someone out there must surely know something about grits and their make up and how they affect the final finish. It seems to me that the harder material (Silicon Carbide ?) would be best at giving the cleanest finish.

In the meantime I can think of no better company for a boat ride than you fellas… as long as we are not up the proverbial creek and someone remembered the paddle, we’ll be okay. :)

I shop at Industrial Abrasives as well and use their papers on all my sanders, but they don’t offer anything comparable to Abralon. Abralon and SIA are foam backed extremely fine grit sanding discs, ranging up to 4000 often used for rubbing out or polishing finishes.
