They can be readily formed into complex shapes.
Density of metals ceramics polymers.
Over the last half century new choices of materials such as ceramics polymers and polymer fibers and lower density metals have significantly decreased the weight of the armor needed for the protection of personnel and vehicles.
Compositions with several allotropessuch as sio2will have minor differences in density.
A material with a high level of hardness will resist deformation caused by surface indentation or abrasion while a material with a low hardness level will deform more.
Materials can be majorly classified in five considerable categories i e.
Density ductility hardness corrosion resistance hardness thermal conductivity electrical conductivity wear resistance.
In fact properties of ceramics and glass can be tailored to specific applications by modifying composition including creating composite materials with metals and polymers and by changing processing parameters.
One of the most desired properties of metal alloys is the hardenability.

Lighter than metals and ceramics.

Metals polymers wood fabrics and ceramics.
Therefore this property of the polymer is highly advantageous because we can replace metal with plastic.
The key difference between polymers and metals is that the polymers are lightweight materials compared to metals.
Mass propertiesinclude things like density.
Non crystalline materials are less dense than crystalline ones.
If we take a ball made of a polymer material such as plastic and a ball made of a metal with the same size we can observe that the metal ball is heavier than the plastic ball.
Ceramics are intermediate in density between polymers lower and metals higher in the range of 2 6 gms cm3.
Metals polymers ceramics wood fabrics.
Their strength stiffness and melting temperatures are generally much lower than those of metals and ceramics.
The table below provides a summary of the main properties of ceramics and glass.
Many new combinations include ceramic fibers in metal or polymer matrix.
These are typical properties.
Usually they are low density and are not stable at high temperatures.
There are other material ranges as well but here in this article most common are being discussed.
