How is the hardness of metal divided?
Most precious metals such as for example gold, silver and platinum have ratings of under 5 on the Mohs Scale, which has a maximum of 10. This scale essentially compares materials by scratching one to a different and rates them based on the hardness. So, anything with rating of 9 can scratch materials of ratings under 9.
On the other hand, a product of rating of 10 can scratch a product of 9, however, not vice versa. Considering that the etching head of traditional engraving machines use are manufactured from steel, which has a Mohs Scale rating of 7, they cannot scratch tungsten carbide rings, because they've a score of 9.
Can Tungsten Rings be Engraved?
For metals that exceed the capability of traditional methods, there are new engraving machines designed with diamond heads. Diamonds have the best rating of 10 underneath the Mohs Scale and thus, diamond engraving machines have the ability to engrave tungsten rings.
However, the fonts with diamond engraving machines is limited: they are on a only very thin lines, not bolder fonts. In addition to it being quite difficult additionally it is very brittle and it's possible that the metal could be damaged from connection with the diamond head of the engraving machine. To preserve the sweetness and integrity of your ring, the easiest way of engraving tungsten wedding rings has been a laser.
