Aluminum Oxide (AO)
AO is formed by combining bauxite and other materials by firing them in an electric furnace. The resultant mass is then crushed, and the pieces are sifted through successively finer screens to assign a grit size (CAMI grading). When crushed, the resulting pieces are naturally pyramidal. Due to the shape and the strength of the materials used in its making, AO is a very durable grain. The grain is worn down during use, sanding finer the longer it's used. So theoretically, you can start at 80 grit, and after you've worked the abrasive for a while, you'll sand more like 100 or 120 grit. Users take advantage of this characteristic by using the belts on multiple machines or applications. For instance, if you have two wide belt machines doing intermediate and finish sanding, respectively, you may use a 120 belt on the first machine to do your intermediate sanding. When the cut for that application is no longer as sharp, the belt can be used for 150-grit application.
As stated above, AO is tough and durable and is used on bare wood, most metals (especially steel), leather, and other materials. It is a great general-purpose grain and probably the most common grain seen today.
Paper
Paper backings are available in different weights or thicknesses using the designations A (the lightest wt.) through F (the heaviest weight). Lightweight papers A-C are commonly used for power sanding with sheets or discs or hand sanding. The heavier weights (D, E & F) may be seen in sheets or discs for power sanding or, in the case of the E & F weights for belts. Only the E & F weight products are considered heavy enough to be belt materials. Some parameters that need to be met before considering a paper belt are:
- Work must be dry. Our waterproof papers are all A/C weights and, therefore, unsuitable for belts.
- Work must be flat. Paper will not follow a contour easily and is more likely to crease, kink, or tear on contoured work than cloth.
- Work should be limited to grits 80 and finer. If you ran coarse grit belts (24-80) in the paper, the backing would wear out before the grain was fully utilized. Paper is extremely well-suited for belts in grits 150 finer, which will result in a finer finish per grit than cloth and cost less.
- Belts should be at least 6-8 in. in width and over 150 in. long. Short belts like portable belts, belts for edge sanders, back stands, or dynafile machines are usually short and narrow and therefore have less cool down time in operation. Heat is the enemy of any abrasive. These shorter belts do not provide time for the heat built up during sanding to dissipate in use, and while they may, at first glance, appear less expensive, they are costlier in the number of belts per piece worked and downtime for the belt change.
Paper can be chemically treated to be waterproof and should be marked as waterproof or with the abbreviation W/D or WP.
