Well I think it's spelled that way. The boys from Milessupply wanted my to try this stuff out. It is 34-50 grit. They use it to sandblast hard stone. I don't know if it is harder that silicone carbide or not. Seems to be doing pretty well. I have been running rock quartz crystals in it for a week and they are rounding off pretty good. Also when I grap one out it is covered with grit. So the grit is lasting more that a week.

Sounds like a good thing to use. Keep us posted.

My research has found that this is predominently used in anti-persperant, but as an abrasive, it seems to out perform Aluminum Oxide. I'd be interested in hearing your assesment of this stuff. The following is copied off a web page, don't think I came up with this information off the top of my head. Aluminum Zirconium- It is a mixture of zirconium oxide dissolved in aluminum oxide at molten temperatures. The type used for coated abrasives has a microcrystalline structure and is characterized as sharp, hard and extremely tough. Because of the microcrystalline structure and extreme toughness, smaller particles of the grain break off in use and at a much slower rate than standard aluminum oxide. It produces superior performance on a wide variety of materials of both high and low tensile strength under high grinding pressures. Materials include carbon steel, stainless steel, tough bronzes, a wide variety of stainless steel and exotic alloys, grey, malleable, ductile and nodular cast iron, aluminum, titanium, etc. Alumina Zirconia is excellent on high grinding pressures applications and very often it is equally effective on many of these same materials at lower grinding pressure levels.

Well it looks like I can use it for two things! Grit and deodarant. The next time I check it I'll splash some on the pits. Hope its not to gritty that I'll get a nasty rash. HAHA Thanks Banjo

That does it. I want some. Sounds like it can really cut down the coarse grit phase. How long has your quartz been in and hows it lookin?

sounds like some good stuff, coarse always seems to take forever. How much is it? is there a minumum order amount?

I'll have to check tonight to see how they are doing. They have been running for 9 days. I'll see if there is any grit left and let you know. The price is less that a buck a pound. I'll look it up tonight as well. To get it call 1-888-283-5863. This is Miles Supplies in Georgia. The only thing I am wondering about is that because this grit is larger than 60-90 do you have to run it through the 60-90 to get the scratches out of the rocks. Maybe not. I guess I'll be finding out soon.

Thats a good point Brett. I guess it might be the deciding factor for me. I'm trying to figure the advantage in running a week in the Alum. Zir. and then run another week in 60/90 to clean up scratches. I suppose you might just as well run 2 weeks in 60/90. Unless of course you intended to run 4 weeks in 60/90 to get the same result you got with one week of each. Clear as mud?

I have a few rocks that I shaped with a tile saw blade and it left me some bad a-- scratches. the coarser grit might just be in order to get rid of them.

Well like a dumb ass I forgot to take a picture of my quartz before I charged it up again. They ran in this stuff for about 12-14 days and the grit wasnt all they way gone. In the pits of the quartz there was grit . About every one had grit left on them. It took all the matrix off and rounded them nicely. They are in 120-220 stage now. Will post pics next time.

Brett, or anybody; have a comparison as to how they thought this compared to the 60/90 SC? When I talked to George at Miles Supply, he was talking at selling the stuff around $1.25 a pound or so. Haven't heard any feedback in a few weeks. Any updates out there?

I'm in need of 60/90 since I recieved my second Thumblers B 15#er. I just use them for rough, and last I talked to Charlie at Miles, he said that the Aluminum Zirconium is very hard and used for sand blasting, and he doesn't usually sell just a few pounds. So before I commit to 50# of the stuff I'd really like to hear how anyone else seems to rate it's performance. Otherwise i'll just order 50# of the 60/90 and disniss the whole notion of substituting the Aluminum Zirconium for the first stage. And in me saying all of that it keeps this topic up in view so it doesn't get buried ;D

I got 5# of the Aluminum Zirconium Friday and put it in my 3# Thumler with some rose Quartz, dry (as an experiment). Then I took my 15# Thumler and put the Zirconium in with a bunch of Agates that I know are troublesome (Moss Agate for one), and this is running wet. I'm gonna see if this stuff is worth the $1.25 a pound I paid for it. They didn't want to sell less than 50 pounds. That was George at Miles Supply. It would be nice if it cut some time off the First stage of tumbling. I'll keep you posted on how they both do. Wet and dry.

yea anybody got anything good to say about this stuff---im gettin ready to place a large order with miles and was wondering if it was worth getting some ,,im happy with the 60/90 and the price is right --but it might be nice to have just for say some stubburn agates or what not

Yes-I tried it wet and dry. The price was $1.25 a pound from Miles. I believe it broke down quicker than SC does, so save your money and just get the 60/90. The Aluminum Zirconium is used for sand blasting and I didn't see any appreciable difference between this and the good old 60/90 Silicon Carbide.

I have one barrel with 60-90 and one with this stuff and they seem to be grinding about the same. I have notice that the aluminum Zirconium needs recharged about every 2 weeks or so. So, Im not sure what to think about this stuff. I will probably stick with the silicon carbide. Some of my thinking is that if you use a larger grit you are going to have to use the 60-90 to make the scratches smaller. Understand what I am saying?
