IrW

IrW is a refractory metal alloy combining iridium and tungsten, two of the densest and highest-melting-point elements in the periodic table. This material is engineered for extreme-environment applications where both thermal stability and mechanical integrity must be maintained at temperatures and stresses that would degrade conventional superalloys. IrW is used primarily in aerospace, nuclear, and precision instrumentation sectors where weight is secondary to reliability and performance at the limits of material science—such as in rocket nozzles, nuclear reactor components, and specialized laboratory instruments.
