Chrome Plating Anodes Material Composition

 Chrome Plating Anodes 


Chrome Plating Anodes are made up of Lead alloying with Tin and Antimony.

Types of alloys used :

 7% tin – 93% lead: Used in all type baths including high fluoride solutions.This alloy has an improved peroxide surface film for better trivalent control and reduced scaling.This alloy is softer and may sag if too heavy or too large. This alloy is recommended for anode weighing upto 25 kgs.

7% Tin – 2 % Antimony – 91 % Lead – This alloy gives benefit of both Tin & antimony. It has improved conductivity and provides rigidity to anode. Anodes of this alloy shows minimal sagging and reduced scaling of surface.

10% tin – 90% lead: This alloy has an maximum improved peroxide surface film for better trivalent control and reduced scaling. Due to more Tin content cost of anode also increases.

6% antimony – 94% lead: This is a very common alloy that was used in the past . The antimony provides both hardness and rigidity and is particularly well suited for large or heavy anodes. The surface film scaling is heavier in this alloy.

Supercon India specializes in manufacturing Lead Tin Anode with various alloying specifications.
