How to choose an anode for your work:
It depends on the material, size and the shape of the item that needs to be plated. These three things determine the anode and solution that you will require. The anode is the positive (‘+’) electrode, which is placed in the tank opposite the object that you are going to plate (cathode) which is a negative (‘-‘) electrode. Anodes should perfectly suit the item being plated so they must be chosen accordingly.
The most popular types of anodes for most popular processes are:
1. Copper anode for the copper plating process.
2. Gold or 316+ stainless steel anode for the gold plating process.
3. Silver or 316+ stainless steel anode for the silver plating process.
4. Nickel anode for the nickel plating process.
5. Brass anode for brass plating process.
6. Platinised titanium or rhodium plated anode for the rhodium plating process.
7. Peroxide Lead Anode for a chrome plating process.
