Emery, of course, is simply less-refined aluminum oxide (corundum, about 95 percent) containing just enough iron (about 0.15 percent) to give it its characteristic color. There's usually about 2-3 percent of titanium dioxide and and a percent or less of silicon dioxide. For more consistent finishes, a more highly refined and graded aluminum oxide is generally employed for surface finishing on metals. For the optics, lapidary, and metals micro-finishing, Linde 'A' or Linde 'B' is usually employed (0.3 and 0.05 microns, respectively). Emery flour need not be this fine for most applications, of course.

Local and online* sources would be lapidary shops that sell tumbling equipment and media. Often, emery flour will be called 'pre-polish' (silicon carbide is the ubiquitous choice for the larger grits, these days). Another source is jeweler's suppliers, as they sell abrasives for both rotary and vibratory tumbling. Many platers will have drums (if not mounds) of emery and will often be glad to give you more than you can use just for the asking. Be sure to take some bags or a bucket. Foundries and mould finishing shops (places that often do fine sand and bead blasting) will often be glad to let you have some abrasives to try. If you find you don't require actual 'emery' for historical or technical reasons, you will have no problem obtaining small amounts of refined corundum grit and powder in a broad range of particle sizes and grades.
