The Attalos Plating Calculator is designed to make electroplating simple, accurate, and accessible. By entering key values such as plating medium, bath type, efficiency, surface area, and desired thickness, you can quickly calculate the required current or plating time. This tool helps both hobbyists and professionals achieve consistent results, whether working with copper, nickel, or zinc. Use it to save time, reduce errors, and bring confidence to every stage of your plating process.
Select the metal you are plating with. Different plating mediums such as copper, nickel, and zinc require unique bath ratios and current density settings for accurate results.
Select the type of plating bath you are using. Commercial baths follow standardized formulations, while homebrew baths use simpler recipes for DIY setups.
Choose your preferred unit system. Select Metric (mm, mm²) or Imperial (inches, in²) to match your workflow and measurement style.
Enter the efficiency of your plating bath as a percentage (0.00–100.00). For commercial solutions, refer to the product’s user manual. If you are unsure, you can calculate it using our Plating Bath Efficiency Calculator
Select the thickness of the metal layer you want to deposit. Thicker coatings provide greater durability and corrosion resistance, while thinner layers are suitable for decorative or low-wear applications.
Enter the total surface area of the part to be plated. The calculator uses this value to determine the required current and plating time. Make sure the area matches your selected unit system (mm² for metric or in² for imperial)
⚠️ Important
You must select either Current or Time in the options below. The calculator will determine the other value automatically based on your input.
Select this option if you want to enter the plating current directly. The calculator will then determine the plating time required to achieve your desired thickness.
Select this option if you want to set the plating time. The calculator will then determine the required current to achieve your desired thickness.
Calculated Values
Recommended Settings
The calculations are based on Faraday’s Law of Electrolysis
Thickness = [I ⋅t⋅100⋅η⋅M] / [n⋅F⋅ρ⋅A]
I = Current (Ampere)
t = Time (seconds)
η = Efficiency (%)
M = Molar Mass (g/mol)
Thickness = μm
n = Electrons Exchanged
F = Faraday's Constant = 96.485 C/mol
ρ = Density (g/cm³)
A = Plated Area (dm²)
100 = Conversion factor from cm to µm for thickness
