Iridium can be deposited by CVD onto a molybdenum mandrel … WebThat 'superhero' feel also comes through in iridium's resistance to corrosion. We're used to gold and platinum as the exemplars of metals that stay pure, but iridium fights off corrosion better than either. It was partly for this reason - and the metal's sheer hardness - that iridium was first put to use in alloys to make the tips of fountain pens.
WebRhenium also has one of the highest modulus of elasticity among all metals, second to only iridium and osmium. As the temperature increases from room temperature to 725 ° C, rhenium’s modulus only decreases about 20%. This property allows for filaments made with pure rhenium to have excellent mechanical stability and rigidity.
