molybdenum disk copper and copper alloy

W is tungsten, copper and copper alloy, tungsten-copper alloy used copper content of 10% to 50%. Tungsten copper alloy powder metallurgy method of preparation, has good electrical and thermal conductivity, good high temperature tungsten sheet‍ strength and a certain plasticity. At very high temperatures, such as above 3000 ℃, tungsten-copper alloy of copper is liquefied tungsten electrode absorbs heat and reduce the material surface temperature. molybdenum disk‍ So this kind of material is also called metal sweating materials. Tungsten copper alloy has relatively wide range of uses, mainly used to manufacture high-voltage electrical arc erosion resistant switch contacts and the rocket nozzle throat, rudder and other high temperature components, also used as EDM electrodes, tungsten weights‍ high temperature mold processing as well as other requirements of thermal conductivity properties and high temperature use of the occasion.

molybdenum wire tungsten is a modern industrial

Tungsten and tungsten alloys Very versatile, tungsten is a modern industrial, defense and high-tech applications in one very important functional materials, and is widely used in aerospace, nuclear, marine, automotive industry, tungsten sheet‍ electrical industry, electronic industry, chemical industry and other areas. Most of tungsten carbide andtungsten bolts in the production of iron. Tungsten and chromium, molybdenum, cobalt alloy molybdenum disk‍  composition for the production of heat-resistant tools, such as gas turbine blades and combustion tube. Tungsten with tantalum, niobium, molybdenum and other components difficult fluxing. Tungsten and tungsten copper silver alloy material used as electrical contacts. High density tungsten nickel-copper alloy as radiation tungsten weights‍ protection shield. Tungsten wire, rods, sheets, etc. for the production of light bulbs, tube components and arc welding electrodes.

tungsten sheet in the same working conditions

Depending on the circumstances, commonly used assessment methods are: 1) in the same working conditions (speed, load, temperature, etc.) tungsten sheet‍  friction surface mount and damage due severity; 2) friction occurs when occlusal load; 3 ) friction in the friction process, the friction torque (friction coefficient) mutated load; 4) based on the wear of friction and wear test surface morphology microscopic analysis. molybdenum disk‍ Tests mainly in dry friction or lack of lubrication conditions. These methods are the main problems is the state of the dry friction wear mechanism and cylinder - piston ring work is significantly different, the test results of simulations of the poor, lack of lubrication conditions are difficult to control, tungsten weights‍ poor reproducibility of test results.
