According to PhysOrg.com article from 2009, a fabric called wurtzite boron nitride has a larger indentation strength than diamond. The scientists who made this discovery have additionally calculated that one other material, lonsdaleite, is even stronger than wurtzite boron nitride and 58 p.c stronger than a diamond. This discovery marked the primary case where a fabric exceeded a diamond in strength beneath the same loading situations. As for the hardness scale, titanium is 36 Rockwell C, while diamond is ninety eight.07 Rockwell C. Recently, magnesium alloy has been used for creating the our bodies of cell phones and DSLR cameras like the Nikon D800 and the Sony A7R.
The Mohs scale of mineral hardness, created in 1812 by German geologist and mineralogist Friedrich Mohs, is used to rate a mineral’s scratch resistance. The methodology of comparing hardness by seeing which minerals can visibly scratch others is, nonetheless, of nice antiquity. … Read More
