Gold - Type I, II, III

Out of Stock

Gold plating is an electrolytic plating process that deposits gold onto a substrate. Gold plating is often used in the electronics industry for its conductivity and long term corrosion resistance.

Gold Plating Types
Type I Hard Gold 99.7% gold purity, Hardness 130-200HK
Type II Hard Gold 99.0% gold purity, Hardness 130-200HK
Type III Soft Gold 99.9% gold purity, 90 HK max

Code A: 90 HK25
Code C: 130-200 HK25

Type I High reliable electrical contacts
Type II Wear resistance (hard) and cosmetic jewelry
Type III Semiconductor Components, Nuclear Engineering, Thermosonic Bonding, Ultrasonic Bonding, Solderability, High Temperature Exposure
