Metal tungsten vacuum sintering process
Tungsten is a widely used metal material with a variety of excellent properties. Its melting point can reach 3410 C, its density is high, and its solid theoretical density can reach 19.25g/em3. In addition, it has high elastic modulus, excellent thermal shock resistance, excellent thermal conduct...
Vacuum Brazing of Waveguide Components
Waveguide components refer to components that use waveguides to control or process electromagnetic waves. Can be used for directional transmission, matching, attenuation or absorption, power distribution, mode (waveform) transformation, isolation, filtering, phase shifting and amplification, freq...
Vacuum sintering of tungsten alloy in controlled micro-atmosphere
High-density tungsten alloy is an alloy system composed of tungsten as the matrix (the content of tungsten is 85% ~ 98%), and a small amount of Ni, Cu, Fe, Co, Mo and other elements are added. Generally, it is divided into W-Ni-Cu and W -Ni-Fe two series. This kind of alloy has a series of excell...
Copper-430 series stainless steel vacuum brazing process
In recent years, a beautiful and practical stainless steel pot with 430 series stainless steel (commonly known as stainless iron) and copper bottom, which can be used for induction cooker, has become popular. The processing of this product involves large-area composite brazing of 430 stainless st...
Plunger Nitriding Process
Iron and steel parts in the active nitrogen medium, a certain temperature and holding time, so that the surface infiltration of nitrogen elements of the process, called nitriding. Although nitriding and carburizing are chemical heat treatments to strengthen the surface of parts, there are signifi...
