Description

 

Tantalum is dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity and is featured the third highest melting point 2996℃ and high boiling point 5425℃. It has the characteristics of high temperature resistance, high corrosion resistance, cold machining and good welding performance. Therefore, tantalum and its alloy are widely used in electronics, semiconductor, chemical, engineering, aviation, aerospace, medical, military industry etc. The application of tantalum will be more and more widely used in more industry with the technology progress and innovation. It can be found in cell phones, laptops, game systems, automotive electronics, light bulbs, satellite components and MRI machines.

 

Tantalum can be manufactured into welded tubing and seamless tubing, which are widely used in electronics, semiconductor, chemical, engineering, aviation, aerospace, medical, military industry.

 

Application: Ta mechanical parts, semiconductor materials, high temperature resistance materials, anti-corrosion materials, electronic materials.

Grade:RO5200,RO5400

Manufacturing Standard: ASTM B521-98

Physical Properties: High melting point, great resistance to corrosion and good ductility.

The comparison of seamless tube/pipe and welded tube/pipe

Type Advantages Disadvantages

Welded Tube/Pipe

 

(Fit for mass production)

  • Uniform wall thickness, internal surface is in good quality
  • High production efficiency and low costs
  • Easy to manufacture larger diameter tubes/pipes
  • Short production term
  • Easy to control prodcts quality

 

  • Poor flexibility, not available to produce various of specifications but small quantity products
  • Welding seam is hard and require skilled person and easy to cause troubles
  • Difficult to clean the welding line
  • Difficult to control ovality
  • Strict dimension requirements for tantalum strips

 

Seamless Tube/Pipe

(Fit for customized production)

 

  • Available to produce small specification tubes/pipes and capillary tube/pipe
  • Excellent flexibility, available to produce various of specifications but small quantity products
  • Uniform performance of the whole tube/pipe

 

  • Uniformity of the wall thickness is difficult to control
  • Longer productivity term but lower finished products rate
  • Complexed equipment requires high investment capital
  • Hard to product large diameter tube/pipe
