If density plays a factor in the strength of an objects gravitational field, why is it not part of Newton`s law of gravitation?

Density does not play a factor in the strength of an objects gravitational field in classical mechanics , mass of the body does. Newtons law of gravitation = classical mechanics.
Though density of the body does affect the gravitational force indirectly by changing the mass of the body as mass = density x volume
If we were to place spherical shaped ball of iron of 1 kg and spherical shaped ball of aluminium of 1 kg both will exert same force outside of their radius at equal distances from center despite having different densities.
Although in quantum mechanics ball of iron should have bigger “distortion in space” and thus bigger “gravitational field”
