About the plating of Silvec's aluminum die-cast ADC12 (surface treatment for rust prevention)
■ Corrosion Prevention for Aluminum Die Casting ADC12: Surface Treatment for Rust Prevention Silvec has extensive know-how in rust prevention treatments for aluminum die casting ADC12 and can provide original technology solutions. ■ Corrosion Resistance and Surface Treatment of Aluminum Die Casting ADC12 Aluminum die casting ADC12 is widely used, accounting for over 90% of the production ratio among aluminum die casting alloys, due to its excellent castability, mechanical properties, and machinability. However, its corrosion resistance is relatively poor compared to other aluminum die casting materials, necessitating rust prevention treatments depending on the application. The four representative treatments for rust prevention of aluminum die casting ADC12 are as follows: 1. Plating 2. Anodizing 3. Chemical treatment (trivalent chromate treatment) 4. Cationic electrodeposition coating

basic information
Regarding the rust prevention effects of ADC12 and various surface treatments 1. Plating The plating properties of ADC12 are not poor. When plating ADC12, it is common to use copper plating or nickel plating as a base layer. There are many cases where nickel plating is processed directly and used as is, but various types of plating can be selected on top of copper plating or nickel plating according to the application. For example, with a total film thickness of about 25μm, "Aluminum Chrome Plating" can achieve no white rust after 500 hours in the JIS salt spray test, and if a black color is desired, zinc plating plus black chromate may be used. Types of plating performed on ADC12 at our company: ■ Copper plating ■ Copper + Nickel + Chrome plating ■ Nickel plating ■ Nickel + Chrome plating ■ Nickel + Trivalent Chrome plating ■ Nickel + Tin plating ■ Nickel + Silver plating ■ Electroless Nickel Plating (NiP) ■ Electroless Nickel + Chrome plating (NiP) ■ Zinc plating + Chromate treatment / Black Chromate treatment ■ Aluminum Chrome Plating (Ultra-high corrosion-resistant chrome plating) *All are RoHS directive compliant platings.
