Mechanical Properties Of Metals Ceramics And Polymers

The key difference between polymers and metals is that the polymers are lightweight materials compared to metals.

Mechanical properties of metals ceramics and polymers.

It is also resistant to corrosion and permeable for microwaves. One of the most desired properties of metal alloys is the hardenability. 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. The type of alloy mixtures is highly dependent on the desired mechanical property of the material.

In addition many of the polymers are extremely ductile and pliable i e plastic which means they are easily formed into complex shapes. While some of the stress strain curves for polymers might look similar to ones for metals polymers are mechanically different than metals or ceramics. In general they are relatively. A highly elastic polymer may stretch over 10 times the original length.

Therefore this property of the polymer is highly advantageous because we can replace metal with plastic. Basis are comparable to the metals and ceramics. Mechanical properties of polymers. Are ferrous and nonferrous metals.

Properties of materials are classified into seven. These are typical properties. Copper is a soft malleable and ductile metal with high thermal and electrical conductivity. Scissors a china tea cup a building brick a floor tile and a glass vase.

Dense high electrical conductivity high to fair thermal conductivities. Alloying can be applied to metals ceramics and polymers where in each specific properties are desired. Majorly composed of al 2 o 3 aluminum ceramic is a dense ceramic material with excellent thermal and electrical resistance properties. Common objects that are made of ceramic materials.

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. 7 22 callister rethwisch 5e. The table below provides a summary of the main properties of ceramics and glass. Metals are of varying types and the applications of metals in the structural and mechanical work are significantly extensive however on primary basis metals can be classified in to main groups i e.

Deform under stress leading to ductile fracture. Mechanical engineering q a library compare metals polymers and ceramics on a chart or table using the following properties and the ratings low high and highest.
