Hotend upgrade - Copper or Alu heatblock?

[mike-998]

Hello guys,

I'm planning to upgrade hotend on Ender 3 v2 Neo. I have a choice between copper or aluminum heatblock. I would like to print at higher temperatures in future (290°-300°). Would be the copper better choice? Or, it will cause problems with hotend MPC calibration?
Many thanks.

This is the hotend I'm thinking about. Should be direct replacement without any modifications.

Nevermind, just found out this hotend is just another chinese crap and waste of aluminum. This thread could be deleted.
