Using data taken by SELEX during the 1996-1997 fixed target run at Fermilab, we study the production of charmed hadrons on copper and carbon targets with ∑ -, p, π -, and π beams. Parametrizing the dependence of the inclusive production cross section on the atomic number A as A α, we determine α for D , D 0, D s , D (2010), Λ c , and their respective anti-particles, as a function of their transverse momentum p t and scaled longitudinal momentum x F . Within our statistics there is no dependence of α on x F for any charm species for the interval 0.1
