Hi-Tech Manufacturing, LLC -
Experts at Machining Tungsten
Hi-Tech Manufacturing and its subsidiary Global Contract Manufacturing (GCM) have extensive experience and expertise in machining tungsten and tungsten carbide alloys.
From small to large components, and from prototype runs to long run production orders, we have the experience to manufacture tungsten and tungsten carbide components to your exact requirements.
Tungsten has the highest melting point of all elements (3422° C), making it ideal for use in high-temperature applications such as TIG welding electrodes and rocket nozzles. In its pure form it is brittle and hard to work, but as tungsten carbide or alloy steel it can be worked to produce highly abrasive-resistant products.
Approximately 50% of tungsten is used in the production of hard materials such as tungsten carbide; the remainder is used in the production of alloys and special steels.
The hardness of tungsten in an alloy such as tungsten carbide makes it ideal for making cutting tools used in demanding applications such as metalworking, woodworking, mining, and construction, as well as in high-performance sports equipment and surgical instruments. Alloys such as high-speed steel contain up to 80% tungsten. The resulting high melting point makes the alloy ideal for products exposed to very high heats such as rocket nozzles. Superalloys containing tungsten, including Hastelloy®, are used in turbine blades and wear-resistant parts and coatings.
Machining tungsten carbide and alloys
Machining tungsten carbide and various tungsten alloys and superalloys requires thorough understanding of their properties. Traditional techniques can result in stresses that make machining laborious. Hi-Tech Manufacturing and Global Contract Manufacturing (GCM) have the experience to use techniques that avoid stresses, degradation and excessive work hardening, and finish components after allowing the material to stabilize.
