Brendan, we want beryllium copper. Its thermal conductivity is much lower than copper (about 1/6 if I remember correctly) and this will significantly reduce the heat transfer from the PCB to the sensor via pins.
And, as you said, the chance of poisoning is virtually zero in the metal form.

Unfortunately the description on AliExpress only says
"material: metal"
Not very helpful.
