Is there a microwave tip on aliexpress?

Question

Soldering

I want to buy a tip for microwave soldering for my soldering station (luckey 936a and other Chinese analogues).
2 or 3mm, probably something like 900m-t-2(3)cm only with a more pronounced groove.
is there something similar on aliexpress?
ps. I used the search, and even tormented the seller with questions. to no avail.
