54A136 - Walter Surfox-M Alu Electrochemical Marking Fluid 5L

Technical Overview of Walter Surfox-M Alu

The Walter Surfox-M Alu (54A136) is a specialized electrolyte solution engineered specifically for the electrochemical marking of aluminum substrates. Unlike standard marking fluids designed for stainless steel, this formulation addresses the unique conductivity and oxidation properties of aluminum alloys. When used in conjunction with a Surfox weld cleaning system equipped with a marking kit (PRO or Standard), the solution facilitates a controlled oxidation reaction on the metal's surface. This process results in a high-contrast, permanent black mark that is integral to the surface rather than a surface coating.

One of the critical technical advantages of the Surfox-M Alu is its pH neutral formulation. Traditional methods of marking or etching aluminum often involve hazardous acids that pose safety risks to operators and require strict disposal protocols. This electrolyte is non-hazardous and safe to handle, significantly improving workplace safety standards. The solution is designed to be highly conductive, ensuring a crisp, sharp transfer of stencil designs, whether they are text, logos, or complex QR codes. The 5-liter packaging is optimized for industrial environments where batch processing and frequent marking operations are required, minimizing downtime for refills.

The marking process utilizing Surfox-M Alu is non-destructive. It does not remove material (etching) in a way that compromises the structural integrity or surface finish of the aluminum part. Instead, it modifies the surface chemistry to create a stable oxide layer. This mark is resistant to mechanical abrasion, chemical cleaning agents, and environmental factors, ensuring traceability throughout the component's lifecycle. It is an essential consumable for industries requiring strict part identification, such as aerospace, automotive, and medical device manufacturing.
