High corrosion-resistant chemical treatment for aluminum. The zirconium treatment generates a chemical conversion coating on the surface of aluminum and aluminum alloys, such as A1100, A2017, and A5052, using zirconium compounds, thereby providing excellent corrosion resistance and improving the adhesion between aluminum alloys and paint films as a primer. Unlike treatments using trivalent chromium compounds, there is no risk of generating hexavalent chromium compounds due to heating or aging. 【Features】 ○ Colorless coating → Treatment can be performed without changing the appearance after processing ○ Does not contain chromium compounds in the coating ○ No risk of generating hexavalent chromium compounds due to heating or aging ○ Chemical treatment compliant with environmental regulations ○ Good paint adhesion ○ Almost no change in the dimensions of the material → Etching may be necessary if thick oxide films, altered layers, or release agent layers are formed ○ Applicable to precision parts For more details, please contact us or refer to the catalog.

High corrosion-resistant chemical treatment for aluminum. The Belscudo treatment generates a chemical film using trivalent chromium compounds on the surface of aluminum alloys such as A1100, A2017, A5052, and ADC12, providing excellent corrosion resistance while improving the adhesion between aluminum alloys and coatings as a primer. 【Features】 ○ Does not contain harmful hexavalent chromium compounds in the film ○ Chemical treatment compliant with environmental regulations ○ Corrosion resistance → Superior to conventional hexavalent chromium chemical treatments ○ Self-repairing properties ○ Suppresses rust formation from film defects ○ Applicable to precision parts → Does not significantly change the dimensions of the material → Etching may be required if thick oxide films, altered layers, or release agent layers are present ○ Excellent coating adhesion For more details, please contact us or refer to the catalog.

High corrosion-resistant plating on aluminum, known as Alon plating, is a plating treatment that provides excellent corrosion resistance with a thickness of approximately 10μm to 30μm, including a base plating, on the surface of aluminum alloys such as A1100, A2017, A5052, and ADC12. The plating thickness can be adjusted based on the desired corrosion resistance. Additionally, the top layer of plating can be selected from various options such as nickel, gold, silver, and chrome, depending on the application. 【Features】 ○ Lightweight ○ Corrosion resistance ○ Ability to add various functions → Conductivity, solder wetting properties, wear resistance, etc. ○ Chrome plating (compliant with environmental regulations) on a base plating thickness of 25μm ○ Passed salt spray test for 500 hours ○ Possibility of weight reduction and cost savings → If brass was used as the material for corrosion resistance purposes → Change material to aluminum with Alon plating ○ No contact marks ○ High functionality ○ Capable of providing finishes from glossy plating appearance to matte appearance with a pearlescent texture For more details, please contact us or refer to the catalog.

Are you under the impression that aluminum materials such as ADC12 and A5052 can only be surface treated with anodizing? Or do you think that aluminum materials can only be plated using a jig for hook plating? Silvec has made barrel plating on aluminum materials, which has traditionally been considered difficult, possible. 【Features】 ○ Significant cost reduction → No costs for jig manufacturing or labor costs for jig setup ○ No need to set the workpiece in a jig ○ Improved corrosion resistance → No contact marks from jig setup on the workpiece → No corrosion from contact marks ○ Very advantageous for dimensional control of the workpiece after plating → Less variation in plating thickness between workpieces compared to hook plating ○ Conductivity → Unlike anodizing, most of the plating film conducts electricity well ○ Choice of specifications → Various coatings that can be soldered are available For more details, please contact us or refer to the catalog.

The solderable nickel plating developed independently by Silvec is an electroplated nickel for soldering. The solder wetting properties of solderable nickel achieve solder wetting comparable to tin plating. Solderable nickel, developed in response to customer requests, has been in mass production for over 10 years. It has a proven track record of being widely adopted in connectors and components used for soldering in low-voltage applications. No additives to improve solder wetting properties are used in solderable nickel plating. Only nickel sulfate, nickel chloride, boric acid, and a gloss agent (equivalent to commercially available and widely used products) are used, ensuring compliance with RoHS directives and REACH regulations.
