GF stands for "Gold Fermented" or plated, so 18K GF means 18 Karat Gold Plated.
no
The gf most probably indicates gold filled, which means the piece is not solid gold. The gf definitely stands for gold filled (it has also been known as rolled gold. Thin sheets of real 18-kt gold are roll-bonded to both sides of a thicker sheet of base metal. This process gives the item (pen, watch, jewelry, etc.) a more durable coating of gold than if it were gold electro-plated (gp).
6 separate 18kOhm resistors wired in series make a total resistance of:18k+18k+18k+18k+18k+18k which is 108 kOhm.6 separate 18kOhm resistors wired in parallel make a total resistance of:1/[(1/18k) + (1/18k) + (1/18k) + (1/18k) + (1/18k) + (1/18k)] which is 3 kOhm.

what does 18K SAC mean in a ring
it is gf
... Depends who you're talking about. My brother has a Gf, I have a gf, do you have a gf?
Probably that it was # 766 of an 18k Design.
What's is 18k TCH nice
18K HGE = 18K Heavy Gold Electroplate = plated and not solid 18K gold ESPO = maker ESP) is Esposito Jewelry whilst ESPO/SIG = joseph esposito
I'm his gf <3
