Varying Specifications Polishing Tantalum Plate For Tantalum Products

Description|

Tantalum has an extremely hard texture and the hardness of 6-6.5. Tantalum is a kind of rare metal with steel grey luster,

and has the melting point of 2,980℃ and the density of 16.6g/cm3.

With similar performance of niobium

1. Tantalum is the third most refractory metal after tungsten and rhenium.
2. Pure tantalum has a slightly blue tint, excellent ductility and can be rolled into very thin (less than 0.01 mm) sheets in the cold state without intermediate annealing.
3. Tantalum is as resistant to corrosion as glass, and at medium temperatures (about 150°C) only fluorine, hydrofluoric acid, sulfur trioxide (including fuming sulfuric acid), strong bases and certain molten salts have an effect on tantalum.
4. Tantalum metal is stable in air at room temperature, and accelerates oxidation to generate Ta205 when heated above 500°C.
5. Tantalum has a series of excellent properties such as high melting point, low vapor pressure, good cold processing performance, high chemical stability, strong resistance to liquid metal corrosion, and large dielectric constant of surface oxide film, etc.
6. It is used in electronics, metallurgy, steel, chemical industry, hard alloy, atomic energy, superconducting technology, automotive electronics, aerospace, and Medical and health care and scientific research and other high-tech fields have important applications.

Material features

Tantalum has an extremely hard texture and the hardness of 6-6.5. Tantalum is a kind of rare metal with steel grey luster, and has the melting point of 2,980℃ and the density of 16.6g/cm3.

With similar performance of niobium, tantalum is an extremely stable chemical element. With high ductility, tantalum can be stretched into thin filaments or prepared into thin foils.

It has extremely small expansion coefficient, only 6.6 PPM expansion after each centigrade increase. Besides, it has extremely high tenacity which is more excellent than that of copper.

Tantalum products have good high-temperature resistance, good strength, as well as excellent acid-alkali resistance and liquid metal corrosion resistance.

The bio-compatibility of tantalum products is increasingly attracting the attention of the medical field.

Achemetal can produce tantalum plates with the purity of 99.95% and 99.99% as well as tantalum-tungsten alloy plates and tantalum-niobium alloy plates.

We also have the machining capacity of manufacturing tantalum plates into finished products.
