Product Description
90 WNiFe Rod is a tungsten heavy alloy rod containing approximately 90% tungsten, with nickel and iron as binder elements. As a W-Ni-Fe tungsten alloy material, it combines high density, good mechanical strength, and improved machinability compared with pure tungsten.
MatMetals supplies Tungsten Heavy Alloy Rods in customized diameters, lengths, and surface conditions to meet different industrial component requirements.
Material Composition
90 WNiFe is a tungsten heavy alloy mainly composed of tungsten, nickel, and iron. The tungsten phase provides high density, while the nickel-iron binder phase improves toughness and machinability.

Why Choose 90 WNiFe Rod?
High Density for Compact Weight Requirements
Tungsten heavy alloy provides a density of approximately 17 g/cm³, allowing designers to achieve higher weight within limited space. It is often selected for components requiring concentrated mass and compact dimensions.
Better Machinability Than Pure Tungsten
Compared with pure tungsten, WNiFe alloy contains a nickel-iron binder phase that improves toughness and machining capability. This makes it easier to process into rods and precision components.
Custom Dimensions Available
Different applications may require specific diameters, lengths, tolerances, and surface finishes. MatMetals provides customized 90 WNiFe rods according to customer drawings or technical requirements.
