Let's first look at the high temperature resistance of the Ta10W spinning tantalum crucible - its melting point can reach 3033℃, which is much higher than pure tantalum and other ordinary metals, and even much higher than common alloy materials. It is fully qualified to meet the operating requirements of high-temperature vacuum furnaces.
Let's talk about corrosion resistance; its performance in this aspect is really outstanding. In boiling hydrochloric acid with a concentration of 20%, the corrosion rate is less than 0.01 mm per year, and it can maintain strong chemical stability regardless of highly corrosive media such as sulfuric acid, nitric acid, or organic acids.
There is no need to worry about mechanical properties. In the annealed state, its tensile strength can reach more than 550MPa; in the cold working state, it can even reach up to 1200MPa. Even in a high-temperature vacuum environment, it can maintain good structural strength and will not deform or crack due to pressure fluctuations.

Let's talk about this precision spinning process. It not only optimizes the structure, but also has a double upgrade in performance. It uses cold spinning technology under vacuum protection. Compared with traditional forging and welding processes, product performance is particularly improved.
Let's talk about its overall structure without welds first. The one-piece molding completely solves the problem of welds being easily corroded. You no longer have to worry about strong acid penetrating along the welds and damaging the container, and the service life is immediately extended.
Looking at ultra-thin walls and high-precision control, the capabilities are really strong. The wall thickness can be as thin as 0.5 mm, the dimensional tolerance can be firmly controlled within ±0.02 mm, and the ovality does not exceed 0.003 mm. Whether it is the narrow installation space in a high-temperature vacuum furnace or the requirements for precise material transportation, it can be perfectly adapted.
Optimization of structural densification is also critical. Spinning can make the grains of the material more regularly arranged and increase the density. In this way, there will be fewer small pores inside the material, and no gas will escape and destroy the vacuum environment at high temperatures.
