Alkaline Zinc/Nickel (12- -15%) 15%) Alkaline Zinc/Nickel (12 Deposit Advantages Deposit Advantages Metal Distribution Metal Distribution (Fasteners) (Fasteners) Alkaline process achieves greater plate thickness in threads and under washers – Better Plate Distribution. The Trivalent Passivate layer can dissolve 1-3 µm of deposit. With acid process it is difficult to achieve superior corrosion protection in these Low Current Density areas. 5 µm required on 8 to 10 µm the thread on the head
