Surface Engineering tested and had some phenomenal results on its PWRDNIA008 rod. The RAD rod is a composite rod, and is part of our Carboride product line. We utilize two types of tungsten carbide – Spherical Cast and Macro Crystalline – with our SP44m nickel matrix. The Tungsten Carbide was distributed uniformly with little or no dissolution. The G65 results came in at a respectable 5.94 mmᵌ volume loss.
