Niobium platinum anode

The niobium-platinum anode is a platinum-coated niobium mesh, which is especially suitable for high-speed and high-current density electroplating solutions. The niobium mesh has excellent chemical corrosion resistance and electrical conductivity. -5 times, so it is the best choice for high plating of precious metals!

The service life is 4-5 times that of platinum titanium mesh, and the carrying current is 4-5 times that of titanium mesh, so the comprehensive performance can save 2.5 times the cost of use than platinum titanium mesh.

Use industry: aluminum wheel electroplating, precious metal electroplating, perchlorate.

product advantages: 

      1. Can produce anodes with complex shapes.

      2. Easy to operate, no maintenance required.

      3. Smaller resistance.

      4. Extremely high corrosion resistance.

      5. Suitable for fluorine-containing electrolyte.

      6. In the case of high current density, it can also ensure a long service life.

      7. The structure is firm and does not deform.

      8. Repeatable platinum plating.

      9. The anodes based on niobium metal are available in mesh, plate, rod, filament and tubular shapes. The thickness of the standard platinum layer is 2-5µm, and under higher requirements, the thickness of the platinum layer can reach 20µm. Compared with platinum titanium anodes, niobium anodes have much higher

Breakdown voltage; especially in the use of electrolyte containing a small amount of fluorine, its service life is long, and the current density can reach 100A/dm2.
