Lightening protection is the reason why. On the Airbus aircraft, there is a difference between early and late models, the later models have more lightening protection strips on them as the weather radar changed. Early weather radar in Airbus aircraft did not have predictive wind shear, later models do, that required the material in the nose to be changed as the frequency the radar operates at is different.
