1、 Core physical properties of tantalum rod

Density: higher than most metals;

Melting point: the third most refractory metal after tungsten and rhenium, with good high-temperature stability;

Boiling point: Fundamentals of application in ultra-high temperature environments;

Hardness: It has both ductility and can be cold-rolled to 0.01mm thin plates.

2、 Key performance advantages

1. Extreme corrosion resistance

Resistant to corrosion by hydrochloric acid, concentrated nitric acid, and aqua regia at room temperature, with an annual corrosion rate of only 0.006mm in sulfuric acid at 200 ℃;

Only hydrofluoric acid and concentrated sulfuric acid can corrode it.

2. High temperature stability

There is no oxidation in the air below 300 ℃, and mechanical strength is maintained in high temperature environments;

The coefficient of thermal expansion is as low as 6.6 × 10 ⁻⁶/℃, suitable for precision instruments.

3. Biocompatibility

No rejection reaction to human tissues, used for orthopedic implants.

3、 Typical industrial applications

Electronic components: high-purity tantalum powder for manufacturing capacitors and semiconductor chips;

Chemical equipment: lining of strong acid reaction vessels, valve seals;

Aerospace: high-temperature components for rocket nozzles, cladding materials for nuclear reactors;

Medical and health equipment: artificial bone nails, surgical sutures.

Note: Density and melting point fluctuations are due to differences in purity; The processing of thin-walled tantalum bars requires controlling the cold rolling deformation rate to avoid lattice embrittlement.
