The metal disadvantage is:
The strength is lost and loses the properties due to corrosion. It greatly affects normal iron by means of corrosion. The main disadvantage of corrosion is the purity of the metal is lost.
The non-metal disadvantage is:
There are several advantages offered by non-metallic bearings such as impact capability, low friction, self-lubricating qualities, and edge loading capability. ... Some bearings have a lower dry coefficient of friction that other non-metallics and definitely less than cutless rubber.

Buildings and Disadvantages Metal may rust, especially if the structure is located outside and at the mercy of the rain. This not only affects the outside of a structure but also the inside of it. Metal buildings are known for being difficult to seal completely from water penetration. Other disadvantages include the difficulty in attaching hooks and shelves to metal, which requires professional tools, and metal's less attractive appearance compared to wooden structures.
