Alloy Armor as a health type doesn't act as armor anymore, it simply has the same resistances and vulnerabilities as Alloy Armor.

So take your Manic Bombard at base level. With 500 Alloy Armor damage receives a 1.75x bonus. Additionally, the damage mitigation due to armor is less effective, meaning rather than 500 armor reducing damage to $300 / (300 + 500)$ it reduces it to $300 / (300 + 500*(1 - 75%))$ instead. Hence, when armor is NOT stripped it will take 1.75x damage from rad vulnerability, multiplied by the $300 / (300 + 500*(1 - 75%))$ from armor damage mitigation. And with no armor you get not bonus for radiation since Cloned Flesh doesn't have a vulnerability to it.

Likewise, the Thumper will get 1.75x damage from rad, times the effective damage mitigation from armor, times another 1.75x from rad because its health is also vulnerable. However, its health is just that, health. It may have "armor" in the name, but it does not have any damage mitigating effects like normal armor would.
