Production Process Of Tantalum-tungsten Alloy

Mixing powder
Weigh the ultra-fine tantalum powder and tungsten powder in the required proportion and then mix them, place the mixed powder in the drum mixer and mix them evenly to get the mixed powder.
Molding
Load the fine powder into the grinding tool and press it into shape.
Sintering the alloy bar into the vacuum sintering furnace, vacuum heating and sintering of the coarse ingot billet

Smelting
The rough ingot is melted several times in vacuum electron beam furnace or vacuum electric arc furnace to make alloy ingot.
Finished product
Ingot performance improvement will be put into the alloy ingot billet into the high-frequency furnace, after heating and forging several times, processing the surface oxidation skin to get the finished ingot according to the size and weight of the profile, material, forging billet, rolling or forging several times, after several times of vacuum annealing to get the bar or plate, and then after machining, grinding to get the good performance of tantalum tungsten alloy finished plate and bar.
