• Tantaline may be supplied with layer thicknesses between 10 and 200 micrometers (½ to 8 mils). For layer thicknesses higher than 200 micrometers (8 mils) tantalum cladding is probably more economical. Critical dimensions and tolerances are maintained of the original part through our etching process.
   
• Standard Tantaline treatment is 50 micrometer (2 mils). A standard Tantaline treatment is most efficient for media with nil corrosion (see “Suitable media”).
   
• For media where slight corrosion of tantalum is expected (e.g. 25% HCl at temperatures above 190 °C or sulfuric acid 98% at temperatures above 175°C) Tantaline layers thicker than 50 micrometers (2 mils) is recommended.

• Parts that can fit into the reactor can be Tantaline treated. The reactor is a cylinder with the diameter of 400 mm (16 in) x 700 mm (27 in) height
   

• Minimum diameter for holes or tubes is ~6 mm (1/4 in). Closed end tubes may be treated inside down to a depth of 5 times the diameter.
   

• Tubing (both ends open) with a length up to 10 times the diameter can be treated inside.
