How to define W alloy

Dear FLUKA experts,
I am a new user of FLUKA. I want to define an alloy material, for example W-0.5 wt.% ZrC alloy. How to set this parameter in FLUKA?
It will be helpful if you kindly guide.

Dear @myy5028,

The definition of materials composed by several elements or other materials is clearly explained in the Materials lecture from the beginner course and in the manual.
