Wiseman briefly analysis of aluminium alloy shell CNC machining surface treatment methods

With The Development Of Science Technology, People Have Put Forward Various New Requirements For The Surface Performance Appearance Of Aluminum Alloy Shell CNC Processing . For Example, When Electroplating Is Used On A Large Area Of Aluminum Alloy Shell CNC Processing Products, People Are Increasingly Tired Of The Luminous Electroplating Luster Turn To Smoky Tones Satin-Like Elegant Tones. Therefore, Electroplating Alloys Were Developed. Here, Huiwen Briefly Introduces Several Decorative Electroplating Alloys Used In Product Surface Decoration.

1. Aluminum Alloy Shell CNC Machining Electroplating Tin-Cobalt Alloy

The Color Tone Of Electroplated Tin-Cobalt Alloy Is Similar To That Of Electroplated Cobalt, But It Is Softer More Popular With People. At Present, It Is Mostly Used To Replace Chromium Abroad. Electroplated Cobalt Is Easy To Be Barrel-Plated, While Electroplated Tin-Cobalt Alloy Can Be Suitable For Barrel Plating Of Small Parts. In Addition, Electroplated Tin-Cobalt Alloy Has Excellent All-Plating Ability Barrel Plating Ability, So It Can Be Used For Workpieces With Complex Shapes. If Double-Layer Nickel Is Electroplated On The Bottom Layer, Its Corrosion Resistance Is Inferior To Electroplated Chromium. In Order To Prevent The Surface Discoloration During CNC Processing Of Aluminum Alloy Shells, The Method Of Impregnation With Chromate Should Be Used, Which Can Also Improve Its Corrosion Resistance. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Processing Experience .

Its Appearance Is A Light Rose Color, Which Makes People Feel Very Good, Has Excellent Corrosion Resistance. If Tin-Nickel Alloy Is Electroplated On A Shiny Substrate On A Bright Nickel Electroplating Layer, A Good Shiny Surface Can Be Obtained. If Electroplating Is Performed On A Matte Surface (Pear Grain) During CNC Processing Of Aluminum Alloy Shells, The Original Condition Of The Surface Can Be Restored. The Electroplating Ability Of The Electroplating Layer Is Very Excellent, There Is Almost No Leveling Effect, So It Is Suitable For Electroplating Of Products Requiring Extremely Fine Lines Rotation Processing.

2. Aluminum Alloy CNC Processing Copper-Tin Alloy Plating

The Low-Tin Bronze Coating Of The Aluminum Alloy Shell Is Pink Golden In Color, With Fine Crystals. It Has High Corrosion Resistance Good Polishing Properties. It Is Often Used As A Protective-Decorative Nickel Base Layer Is Used In Light Industry, Handicrafts, Mechanical Instrument Industry Other Industries. The Medium-Tin Bronze Coating Is Golden In Color Has Good Corrosion Resistance. It Is Mainly Used As The Base Layer For Decorative Chrome Plating.

Welcome Partners With Parts Processing Needs To Call Us For Quotation. The Hardness Stability Of Aluminum Alloy Processing In The Air Are Higher Than Those Of Low-Tin Bronze Coating. However, Due To The High Tin Content Of The Coating, The Base Layer Of The Protective Decorative Coating Is Prone To Flower After Chromium Coating, Which Is The Weakness Of The Medium-Tin Bronze Coating. The High-Tin Bronze Coating Has A Beautiful Silver-White Luster Good Polishing Properties, High Hardness Wear Resistance. In Industrial Design, It Is Used To Replace Silver Chromium As A Protective-Decorative Surface Coating For Reflective Equipment, Instruments, Daily Commodities, Etc.
