Technical Data Sheet
24K Brush Plating Gold Solution
Custom GOLD Plating's24K Brush Gold Plating Solution is gold electroplating solution with added cobalt hardened acid which will yield a relatively low stress, fine grained deposit with a hardness range of 130-200 Knoop. This solution is ideally suited for automobile and motorcycle accessories, electronic circuit board fingers and contacts as well as fine select applications such as jewelry and other decorative deposits.
The purity and hardness of the final electrodeposited gold will be equivalent to Type I, and II, Grade C, specifications as indicated in MIL-G-45204C, & MIL-DTL-45204D as follows;
Content: Varies – standard solution contains ~4 grams per 280grams solution ~ (8.5oz)
Purity: 99.7 percent gold minimum, (24 karat), Type I & II
Hardness: Knoop hardness 130-200, Grade C
Density of Plate: 12.64 mg/in²/µm thick
Theoretical Coverage: ~ 1300 in²/1oz solution to an average thickness of 10 micro-inches (0.25µm).
Note: this coverage is based on the assumption that all gold in the solution will be deposited.
In actual practice this is not likely since there is normally solution loss during use.
