Iron Powder

Hey guys working on a little invention of mine, I need Iron Powder less then 50 microns large and about 10 pounds the cheaper the better thanks alot!

I used to go to the local machine shop and clean their surface grinder. Lots of find dust, it was free, and they paid me to clean the machine once a week.

Might be worth a try

When I mean fine I mean I need it to be around the same as flour do machine shops have stuff that fine I would not think so let me know I may go check it out.

My machine shop only has HUGE chunks compared to flour..

My brake lathe as stuff about the size of salt grains. WAYYYY huger than flour, measureable in thousandths, not microns..

I've used iron powder in spray weld equipment for building up worn shafts.

You might actually try and look at arts and craft supply stores. I am a sculptor, and a lot of the time we cast things in resins since actual metal castings are far more $$$$$, and to make them look like metal we add metal powder to the resins which gives them the same visual properties as the actual metal. I am only familiar with bronze, aluminum, and copper, but I'm sure there has to be iron powder somewhere in there. The grain size is pretty small, way smaller than anything I've ever seen at a machine or brake shop, so I figure it's worth a shot.

Other than getting the powder directly from an industrial manufacturer, the only brand I can think of off the top of my head is called Mona Lisa Mixing Metal Powder.

I hope this helps....

Ebay is probably a good bet. I've bought aluminum powder there, as well as other chemicals.

You can try a place that sells laboratory supplies since I know in all of the Chemistry classes that I took, you can get Iron from shavings to fine powder.

the flywheel grinders used in most autosupply stores that do flywheel resurfacing is really really fine like flower. i am sure they will let you have it for free its a dirty job to clean the fill tanks, its under the machine and usually wet and caked but you could let it sit in a baking pan in the sun and then sift it out.

Tried art stores in my city, no go.

Called machine shops and they wont let me have any, or cannot understand what I am asking for anyone got any other idea's thanks.
