How to Use This Calculator

Enter Part surface area (sq ft), Target thickness (mils), and Anodize type (1-3).
Set Current density (ASF), Bath temperature (°F), and Bath concentration (%).
Adjust Electricity cost ($/kWh) as needed.
Review Anodize time (min) and Dimensional growth (mils).
Use Total current (amps) and Operating voltage (V) to inform your decision.

How the result changes with Current density (ASF)

Part surface area (sq ft): Total surface area of parts being anodized.
Target thickness (mils): Desired oxide thickness in mils.
Anodize type (1-3): 1=Type I (chromic), 2=Type II (sulfuric), 3=Type III (hardcoat).
Current density (ASF): Amps per square foot of part area.
Bath temperature (°F): Anodizing bath temperature.
Bath concentration (%): Sulfuric acid concentration by weight.
Electricity cost ($/kWh): Electricity cost per kilowatt-hour.

Identify Input Parameters
4 parameters
Part surface area (sq ft) = 5, Target thickness (mils) = 0.7, Anodize type (1-3) = 2, Current density (ASF) = 18 = 7 input(s) provided
Calculate Anodize time
Anodize time = targetThicknessMils / (effectiveRate * currentDensityAsf)
49.9 = 49.9
Calculate Dimensional growth
Dimensional growth = targetThicknessMils * 0.5
0.35 = 0.35
Calculate Total current
Total current = currentDensityAsf * partAreaSqFt
90 = 90
Calculate Operating voltage
16 = 16
