Coventya Inc. (Brooklyn Heights, Ohio) has introduced Alumal Elox 557, a liquid product designed to enhance the conventional anodizing electrolyte based on sulfuric acid. Added to sulfuric acid, it significantly improves the efficiency of the process and layer performance.
The advantages of the Alumal Elox 557 is extensive. The product changes the microstructure of the oxide by increasing the number of smaller pores, which yields a more even structure. Alumal Elox 557 offers the following benefits:
- Improves the layer quality by increasing hardness, brightness, color penetration and efficiency of the sealing process, this increases the productivity by 15-25% due to improved oxide formation rate and lowered oxide dissolution rate.
- Allows work up to 30°C avoiding the formation of powdery layer or burns and savings of electric energy up to 50% due to lower applied voltages and reduced cooling requirements.
- Increases the tolerance in dissolved Al up to 27 g/L which extends the solution life, savings of sulfuric acid consumption up to 40% due to decreased dissolution rate and reduced frequency requirement of solution replacement and is compatible with hard anodizing process.
