coarse grained polycrystallne Cadmium?

Hi all,
Does anyone have experience with polycrystalline Cadmium (high purity)?

I am looking for coarse grained cadmium (about ~1mm size of grains) because I want to see some mechanical behaviors with different crystallographic orientations.  It’s not easy for me to find cadmium ‘with coarse grain size’.

Thanks in advance,
Seok-Woo Lee
