Types of Materials


Ceramic material properties

Ceramics

Ceramics is categorised into three types; glass, machineable ceramics and quartz.
1. Glass - is an amorphous (non-crystalline) solid material that is typically transparent and brittle.
2. Machineable ceramics - are a type of engineering ceramic that is designed to be easily machined using traditional metalworking methods such as drilling, milling, turning, and grinding.
3. Quartz - Quartz is a crystalline form of silicon dioxide (SiO2) and is one of the most abundant minerals on Earth.

Elements material properties

Elements

There are 118 known elements each with its own unique properties. The main types of elements, are classified based on there properties, below is a last of each type:
1. Alkali Metals
2. Alkaline Earth Metals
3. Halogens
4. Metals
5. Metalloids
6. Noble Gases
7. Non Metal

Fluids material properties

Fluids

Typical types of oils used in engineering include; lubricating oils, heat transfer oils, hydraulic oils and transformer oils.
1. Lubricating Oils - are used to reduce friction and wear between moving parts in machinery.
2. Heat Transfer Oils - also known as thermal fluids, are used to transfer heat from one location to another.
3. Hydraulic Oils - are used to transmit power in hydraulic systems by applying pressure to a confined fluid.
4. Transformer Oils - are used as insulating and cooling fluids in electrical transformers.
