Product introduction:
Tantalum has a melting point of 2996℃ and a density of 16.6 g/cm. Tantalum is widely used in electronics, semiconductor, chemical industry, machinery, aerospace, medical treatment, military industry and other industries due to its high temperature resistance, corrosion resistance, good cold processing and welding performance. With the continuous progress and innovation of science and technology, tantalum will be more and more widely used in various fields.
Tantalum can be used in a wide range of applications in the manufacture of welded and seamless tubes. Seamless tubes are manufactured by extrusion, tube reduction, or deep drawing with sheet metal. The welding is made by forming a strip, then forming a tube, and then welding the joint with a gas tungsten arc (GTAW).
Capillary size: Outer diameter Φ0.2 ~ Φ8mm, wall thickness T0.015 ~ 0.5mm.
Highest accuracy: Outer diameter Φ±0.003mm, wall thickness T±0.005mm, length L±0.05mm.
External view: Under the microscope, the inside and outside surface of the pipe presents a uniform metallic luster, no oxidation, hydrogenation discoloration, scratches, deformation, burr, etc
Seamless tube
Generally suitable for the production of large quantities of small specifications of products, the advantages and disadvantages of seamless tube are as follows:
| advantage | shortcomings |
1: Can produce small size pipe and capillary material
2: Good flexibility, suitable for the production of small batch, many specifications of the product.
3: The performance of all parts of the pipe is uniform | 1: The uniformity of wall thickness is difficult to control
2: Long production cycle, low yield
3: Complex equipment and large investment
4: difficult to produce large diameter pipe |

About Tantalum metal.
Melting Point: 2996°C
Density: 16.6 g/cm3
Product range:Pure tantalum&Tantalum tungsten alloy
Tantalum is dark, dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity.
It has a melting point exceeded only by tungsten and rhenium.
As a high melting point metal, tantalum possesses a low vapour pressure and good electrical and thermal conductivity up to very high temperature.
The advantages of Ta are excellent corrosion resistance, high high-temperature strength, good machinability and good biocompatibility.
Features:Tantalum belong to the high melting point ,high boiling point rare metal color ,steel ,ductility and corrosion resistance
