Osmiridium / Wolfram. Whether made of gold or stainless steel, each one of the nibs in the company I worked for had an iridium bead of 1mm diameter welded on its tip to reduce nib wear through writing as well as the friction between the nib and the paper. Casually, we call it iridium, but actually, its proper name is osmiridium. In nature, osmiridium occurs as an alloy, containing 30 – 60% ...

Iridium is a chemical element with the symbol Ir and atomic number 77. A very hard, brittle, silverywhite transition metal of the platinum group, iridium is considered to be the seconddensest metal (after osmium) with a density of g/cm 3 as defined by experimental Xray crystallography. However, at room temperature and standard atmospheric pressure, iridium has been calculated to have ...
