What level is a Mohs hardness of 6H?

A: Mohs hardness is a standard for measuring the scratch resistance of materials. Guanfudun Mohs 6H is the self-test data of the Woowhead brand laboratory under the standard test environment. Generally, it can resist minor scratches from daily keys, coins, etc. Common Mohs hardness references for items: nails about 2.5, copper keys about 3, knives about 5.5, sand (quartz) about 7. It should be noted that the Mohs scale of 6H is lower than that of sand (quartz 7). If the mobile phone comes into contact with sand/dust, it may still be scratched. Higher than keys and coins, keys and coins in daily pockets generally won't get scratched. Guanfudun is made of Nanshan high alumina glass as the base material and undergoes a three-time strengthening process. It is also equipped with a wear-resistant reciprocating process of 10,000 times (tested in the brand laboratory), ensuring its daily scratch resistance.
