MOOS hardness

MOOS hardness

MOOS hardness

(OP)
Hi all,

I work for an abrasives company and we've just had a request from a customer regarding plastic automotive badge finishing.

The plastic type was not known by our rep (always useful), but he quoted a moos hardness of 4.

I have never come across Moos hardness before; could someone please let me know how this relates to other hardness scales e.g. Mohs etc?

RE: MOOS hardness

I think you might mean Mohs hardness. It's a hardness scale used in the minerals field. Diamonds have a hardness of 10, Talc 1, and Quartz has a hardness of 7. Relatively, a pen knife will scratch anything up to 6.5 and a fingernail upto 2.5 on the scale.

Nope, asked him about that and it's definitely Moos.

RE: MOOS hardness

Maybe it's the pronounciation.

RE: MOOS hardness

A quick google search would indicate that the Moos Hardness Scale the Russian equivalent to the Mohr's Hardness scale. It seems to have the same values for the same minerals.
