With high density, high modulus of elasticity & strength, high hardness and rigidity, excellent electrical & thermal conductivities, low thermal expansion coefficients, high absorption to X-ray and g-ray, with welding and machining ability.Tungsten alloy ultra thin sheets find many applications in space, aeronautics, military, petroleum drilling, electrical devices, medical industries and measuring systems as well. Tungsten alloy sheets, especially thin ones are used the very frequently, even though, they are the most difficulty to manufacture. Based on patented technologies of company, it of high density tungsten alloy sheet has been mass-produced and exported to many countries and regions such as USA, Mexio, and Eurpe. The high-density tungsten alloy ultra thin sheet is awarded the advanced Hi-Tech award.
A method of producing a high-density tungsten alloy ultra thin sheet utilizes a thin-gage sheet or foil substrate of a first alloy constituent as a starting material. A prescribed mixture of tungsten metal powder and a second metal alloy constituent powder, such as nickel, is loaded on the substrate and partially consolidated in a protective atmosphere furnace to form a porous tungsten alloy sheet skeleton that is also partially bonded to the substrate.
Tungsten alloy sheet is then preferably cooled in a protective atmosphere and sheared into desired lengths. The sized pieces of tungsten alloy sheet are then further heated in a protective atmosphere at gradually increasing temperatures to a point above the melting point of the substrate, where upon the substrate sheet or foil melts and infiltrates the porous tungsten alloy skeleton to complete the densification of the tungsten alloy sheet.
Specification of Tungsten Alloy Ultra Thin Sheet:
