Density of metals ceramics polymers.

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. Lighter than metals and ceramics. Ceramics are intermediate in density between polymers lower and metals higher in the range of 2 6 gms cm3.

One of the most desired properties of metal alloys is the hardenability. Many new combinations include ceramic fibers in metal or polymer matrix. Moderate to low density high strength depends on the quality of the specimen. There are other material ranges as well but here in this article most common are being discussed.

They can be readily formed into complex shapes. The table below provides a summary of the main properties of ceramics and glass. Therefore this property of the polymer is highly advantageous because we can replace metal with plastic. Metals polymers ceramics wood fabrics.

Materials can be majorly classified in five considerable categories i e. 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. 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. Alloying can be applied to metals ceramics and polymers where in each specific properties are desired.

Mass propertiesinclude things like density. 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. Their strength stiffness and melting temperatures are generally much lower than those of metals and ceramics. These are typical properties.

Usually they are low density and are not stable at high temperatures. Start studying metals ceramics polymers. Compare metals polymers and ceramics on a chart or table using the following properties and the ratings low high and highest. Compositions with several allotropessuch as sio2will have minor differences in density.
