Tungsten Machining Service


Part made with 5 Axis milling out of tungsten for the Laser Industry

Due to the metal’s hardness and how difficult it is to machine, most machine shops shy away from working with pure tungsten and other tungsten grades and alloys—but we don’t. Portland Precision Machining Company has many years of experience in machining tungsten, and can deliver tungsten parts that match your designs exactly and meet your tolerances within ±0.0005” or better.

Advanced CNC machining systems enable us to produce even the most intricate tungsten machined parts with unparalleled precision and repeatability, and in any quantity your project requires. Request a quote or contact us for turnkey tungsten machining service.

Why Use Tungsten?

Originally known as “wolfram,” tungsten is a rare earth metal known for its high hardness, high density, and high tensile strength. It is naturally corrosion resistant, and has the highest melting point of all metals, over 3,000°F. In its unalloyed form, pure tungsten is also quite ductile.

Tungsten machined parts are used in numerous, wide-ranging applications, from high-end optics to jewelry to high-powered lightbulb filaments. The material’s density makes it useful as counterweight or ballast for boats and race cars—tungsten counterweights can be up to 75% smaller than copper counterweights of the same weight. Its high melting point makes it popular for countless high-temperature applications, such as rocket engine nozzles.

Machining Tungsten with Portland Precision

Portland Precision is one of few manufacturers in our industry who are capable of accurately and effectively machining tungsten in all grades. Using state-of-the-art equipment and special proprietary processes, we provide start-to-finish service for tungsten machined parts, whether you need prototypes, one-offs, or full production runs with quantities in the tens of thousands.

We also offer an array of secondary operations—surface finishing, etc.—to add further value to our machined tungsten parts. We can machine in tapped holes and other special features, as your designs require. Our secondary services will save you valuable time and money in the production process.
