Mass propertiesinclude things like density.
Density of metals ceramics polymers.
Lighter than metals and ceramics.
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.
Metals polymers wood fabrics and ceramics.
Compare metals polymers and ceramics on a chart or table using the following properties and the ratings low high and highest.
Metals polymers ceramics wood fabrics.
Many new combinations include ceramic fibers in metal or polymer matrix.
Alloying can be applied to metals ceramics and polymers where in each specific properties are desired.
One of the most desired properties of metal alloys is the hardenability.
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.
Their strength stiffness and melting temperatures are generally much lower than those of metals and ceramics.
Ceramics are intermediate in density between polymers lower and metals higher in the range of 2 6 gms cm3.
The key difference between polymers and metals is that the polymers are lightweight materials compared to metals.
Density ductility hardness corrosion resistance hardness thermal conductivity electrical conductivity wear resistance.
Usually they are low density and are not stable at high temperatures.
Non crystalline materials are less dense than crystalline ones.
Materials can be majorly classified in five considerable categories i e.
Learn vocabulary terms and more with flashcards games and other study tools.
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.
There are other material ranges as well but here in this article most common are being discussed.
Therefore this property of the polymer is highly advantageous because we can replace metal with plastic.
Start studying metals ceramics polymers.
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.
These are typical properties.
The table below provides a summary of the main properties of ceramics and glass.
