You can google "smearing temperature in metal" for getting more detailed information. e.g., http://cmt.dur.ac.uk/sjc/Castep_Lectures2/lecture16.PDF
note that there are serval seaming functions that can be used, so that to ask a specific number without choosing a functions is meaningless. e.g., in this work we used 0.005 Hartree Dirac smearing function to converge bulk aluminum. https://arxiv.org/pdf/1811.12217.pdf arXiv:1811.12217v1 [cond-mat.str-el] 29 Nov 2018<https://arxiv.org/pdf/1811.12217.pdf> 2 FIG. 1. (Left and right panels) Calculated spectral functions (shifted along k z as detailed in [45]) and (middle panel) exper- imental ARPES image in the L direction. The results of ab initio GW+C calculations are without (left panel) and with arxiv.org you care calculating a standard testing system, you can find a lot of references on bulk aluminum first-principle calculations. You should search for them and read them, and compare your results with them.

Can I know a range of values?
