Product Detailed Introduction
1. Core materials and processes
Our pure tantalum perforated sheets are made of ASTM R05200 (Ta1), R05400 (Ta2) and other national/American standard high-purity tantalum ingots as raw materials. After vacuum melting, rolling, and annealing, the porous processing is completed through precision laser drilling/CNC stamping processes. The processing accuracy and surface quality are strictly controlled throughout the process:
Tantalum purity: conventional 99.95% (Ta≥99.95%), customizable 99.99% ultra-high purity tantalum flakes
Processing technology: laser drilling (suitable for micro-holes and high-precision requirements), CNC stamping (suitable for batch and large-diameter requirements)
Surface treatment: Bright annealing, pickling passivation, polishing, sandblasting and other customized surface treatments can be provided
Tolerance control: dimensional tolerance ±0.05mm, hole diameter tolerance ±0.02mm, hole position accuracy ±0.03mm, meeting high-end industrial requirements
2. Structure and performance characteristics
Tantalum itself is a rare and refractory metal. It has the characteristics of high melting point (2996°C), strong corrosion resistance (resistant to almost all inorganic acids except hydrofluoric acid and oleum), particularly good biocompatibility, stable electrical and thermal conductivity, and strong radiation resistance. The perforated structure further expands its application scenarios:
Porous structure enables uniform fluid/gas distribution, filtration, heat dissipation, electrode conduction and other functions
The tantalum matrix can ensure the long-term stability of the product in extreme environments such as high temperature, strong corrosion, and vacuum.
We can customize the hole diameter (0.1mm-10mm), hole shape (round hole/square hole/special-shaped hole), hole arrangement (equivalent triangle/square/staggered arrangement), plate thickness (0.1mm-10mm), and overall size (square/round/special-shaped) according to customer requirements or drawings.
