Pure copper is a soft metal and does not have any memory retention properties. Copper contacts of the IEC will not hold the female contacts tightly against the IEC inlet male plug blades...

I disagree, all audiophile IEC’s even from Furutech or Oyaide have the conductors of pure copper.
Are you sure about that? All female IEC connector contacts are made of pure copper? I see the Furutech says pure copper but I would bet the copper has some sort of a alloy that gives it memory tension.
Furutech top line grounding type 125V duplex receptacles use copper contacts but you will notice Furutech uses a non ferrous stainless steel spring clip for its’ memory tension to maintain a tight solid fit connection against the male plug blades.
Here is what Oyaide uses on the C-004 female IEC connector. Beryllium provides the memory tension.
The basic material for the Oyaide C-004 is Beryllium Copper, which provides maximum conductivity, strength, and a secure contact.

I have an AudioQuest 125V duplex outlet that also uses Beryllium Copper for its’ contacts.

I would suggest you check with a credible source if the IEC connector you are looking at is just pure copper.... Pure copper alone is soft copper.
