Niobium Tube Technology
|
|
One of the niobium tube extrusion production method includes the following steps: preparation, a power frequency induction heating (600 + 10˚C), glass powder lubrication, secondary power frequency induction heating (1150 + 10˚C), reaming (reduction of area is not greater than 20.0%), thrid power frequency induction heating (1200 + 10˚C), small deformation, extrusion, extrusion ratio is not more than 10, reduction of area is not greater than 90%) and air cooling technology, finally the hot extrusion process of niobium tube is finished. |

Molybdenum tube Application
•1, good corrosion resistance (The surface of molybdenum tube is easy to produce a layer of dense natural protective film, It can be well to protect the matrix from corrosion by artificial anodic oxidation and coloring, good casting performance can be cast aluminum alloy or processing Plastic deformation of good aluminum alloy.)
•2, alta resistência (molybdenum tube have the high strength.After a certain degree of cold processing can strengthen the matrix strength, some grades of molybdenum tube can also be enhanced by heat treatment)
•3, good thermal conductivity (The conductive thermal conductivity of molybdenum only less than the silver, copper and gold)
•4, easy processing (After add some certain alloying elements, you can get a good casting p erformance of aluminum alloy casting or processing plastic deformation of aluminum alloy)
