Tungsten Carbide and Metallic Assemblies – Practical Design Considerations

Tungsten Carbide, basically a powdered metal containing the components of tungsten and carbon, has for quite some time been utilized for mechanical parts in applications requiring wear obstruction, disintegration opposition, sturdiness, and compressive strength, for example, in mechanical shaft seals, siphon direction, valve trim, into opening oil and gas devices for the Oil and Gas, Petrochemical, Energy, and different ventures. In any case, what causes Tungsten Carbide to perform so well in these applications are a portion of the very qualities that make integrating the material into mechanical plans more testing from both a mechanical and an expense viewpoint.

Dissimilar to metals, Tungsten Carbide doesn’t fit normal creation techniques like welding, nor normal connection strategies, for example, stringing and blasting. The material can’t be welded, and stringing it requires expensive crushing or EDM activities. Moreover, as the material won’t yield-rather breaking when its cross over crack strength is surpassed darting turns into a mechanical test. Further worsening plan difficulties is Tungsten Carbide’s mass, which is more noteworthy than twice that of 4140 steel.

To resolve issues Pacific Metals of manufacture, gathering, mass, and handling costs, fashioners have used a few joining cycles to connect Tungsten Carbide to another essential part or to a temporary metal part like a strung supplement; among these connection techniques are brazing, sticking (regularly with high-solids epoxies), and therapist fitting. While every one of these strategies for connection has its place, on the off chance that the parts are round, similarly as with mechanical seal faces, valve trim, and many into opening devices, shrivel fitting offers the broadest scope of mechanical capability.

Contract squeezing Tungsten Carbide parts into mating metallic parts is a cycle by which the metallic part is warmed to extend its drag past the measurement of the Carbide parts, and after getting back to room temperature brings about a grasping power normally portrayed as “obstruction”. Among the plan contemplations for the impedance joint between the Carbide and metallic part are working temperature, differential tensions, and the mechanical properties of the amalgam utilized.

For those new to planning for Tungsten Carbide parts and congregations, this fills in as the briefest presentation. Administration, plan, and cost contemplations are horde, and your certified Tungsten Carbide producer can help with planning for good assistance and most reduced commonsense expenses.
