Mitsubishi and Fujitsu 5964a ( wifi amplifier 5.9 Gzh )
Alcatel 1 IE35 2 3550506930 5.825-7.150 ( microwave RF isolator )
Okay...gold content? Value? I have 100s
It's just a best guess. ( Hard question to answer )
First do the scratch test and determine that it's gold plate and not solid gold.
Next go on line and look up the most likely parts per million for rich gold plating.
Next ... weigh it up and do the math.
Hypothetical example:
It weight one ounce. Plating over a nickel alloy underneath is at 12 PPM
There would be 12 millionths of an ounce per unit ?
The guys at the gold refining forum might know more about them because recovery is their specialty ?
The 2 amplifiers will have the most gold content. The gold plating will be very thick.
On the Fujitsu component it looks like the gold plated lid is attached with a gold tin solder. That is what makes the gold content so high. If the Mitsuz has a silver colored line between the lid and body the the component then it will be gold tin solder as well.
I am not sure about the isolator gold content. The 2 blocks on the right side of the picture may be gold plated aluminum.
From the looks of the blocks they looked tarnished or maybe has metal migration making the gold plating tarnish.
Most microwave and radio frequency items that are gold plated will have a thick gold plating. The gold plating is used for shielding.
Weigh them up and see what you have. If you aren't going to keep them put them on ebay.
Thanks for answers....i kinda knew the blocks on left were gold plated wasnt sure about unmarked blocks on right any easy way to test before i put on ebay
Posted these over on gold forum.........Sad to say don't get much help over there........Not looking to refine just would like to know if the blocks on the right actually contain any amount of gold before posting on ebay........I'd throw them away before trying to deceive someone
You have to assay them, ether yourself, or a professional. I can not tell you how much gold they have, just that they are electroplated with an unknown alloy. Generally the more yellow the gold is, the less pure.Quote:

The specific type of RF isolator shown above ( new ) goes for $15 - $35 on Ebay
Here are more detailed pics..........There was a member who was nice enough to test a sample of material before similar to this but he hasn't posted in a while
Wow I figured the more yellow the gold was the more pure

seems I have a new fan...........appreciate all the thanks!!!
let us know how it goes...
He instantly sold them, so I'm guessing they were WAY under priced :l
Possibly....that was kind of my intent to sell them that fast.....if i went to mcdonalds to get my kids a hamburger i highly doubt they would accept those little pieces of scrap as paymentQuote:
