content: Quote from: 5U4GB on April 26, 2025, 08:02:30 amIt may very well be... I'd verify.A year or so ago I bought 100 pack of semi rigid coax Sma connectors from Ali. Entire bag for few bucks. One costs that much locally (not even a big brand, just no name connector like tgat costs like $4~5 from local sellers). I've been using them since for up to 5GHz. No problem. No increased loss etc. Sometimes good deals happen.

content: I check by seeing if they are magnetic (steel), and then file one of them to see if they are some alien plated-brass like that last crimp conns I got.Copper is the new gold in china.

content: Well I can't find anything like that even searching for it by loading the picture you sent. Either they are too cheap and one doesn't see a the word "copper" anyhwere on the listing, or they are quite a bit pricier. Number of result listings is overwhelming anyway. So giving up.Anyway, these connector are for solder or for crimping. I guess you wouldn't be interested unless they are for crimping, but then, what wire section/AWG are they for? And, what would be the crimping tool?

content: It's very hard and usually hidden for Aliexpress ads to have the word "copper" clearly stated. With crimp terminals, wire etc. You have to be really careful and not naive.Aliexpress is full of vendors misleading and sending junk. Yes the nation can build some things well but they take pride duping Westerners you know.I like the gold-plated steel they sell, I have no idea what that fake metallurgy is. Sure looks pretty though.I had to laugh I got "16A" rated crimps yet they were quite thin. I would not expect them to carry high current because my "real" crimps are twice as thick the copper.Another point to watch.

content: Quote from: floobydust on April 28, 2025, 03:30:55 amYep. No wonder they do it, after more than a hundred years of being humiliated, exploited and starved by opium sellers. I remember seeing a picture of a seemingly very old man in Sanghai in the 1930s. Should I ever look like that, please have me shot.When complaining, I usually remind them that I'm the kind of white man that traded with China for some 300 years and never occurred to us we could use opium to pay, we used good silver (stolen from Peru, yes) instead. It works wonders every time.But, one is at risk anyway.https://aliexpress.com/item/1005005655600007.html. When I try to upload my review from "My orders" I'm getting 404 error and "This product is not available from your location". LOL. Of course I can get the same product again since the listing is still available from here. First time I see this method to avoid complaints. I got some of these in order to get free shipping for another item. So a cheap check.Please look at the attachments, first one is product description "Gold plated copper", second one is a picture after some filing.

content: In term of cheap copper spade I think the simplest is to buy from Xuanyi Technology on Taobao. Its real copper and they are gold plated. 0.85USD each. They also carry bare copper if you prefer.https://shop70023207.world.taobao.com/
