Nilson in Scandinavia. WebAlternatively, Tennant could have reflected on its extremely high melting point, of nearly 2,500 degrees Celsius. That '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.
