Material, abbreviated as MATL, is the matter an object is made of. There are four categories of material: ceramic, composite, metal and polymer.
- Ceramic - inorganic non-metallic solid comprised of either metal or non-metal compounds made by heating together these materials.
- Composite - material mixture of two or more materials with different properties combined to produce a new material.
- Metal - chemical elements that are good conductors of heat and electricity.
- Polymer - a long chain of molecules linked together.

- Annealing - A method of heat treating used to relieve stress and increase softening.
- Capacitance - The ability to hold an electric charge.
- Capacitor - Behaves as a charge storage device. Holds an electric charge when voltage is applied across it and gives up the stored charge when required.
- Cleanroom - A room/facility in which the air supply, air distribution, filtration of air supply, materials of construction, and operating procedures are regulated to control airborne particle concentrations to meet approperate cleanliness levels.
- Composite material - A combination of two materials with different chemical and physical properties.
- Conductor - A material through which heat passes and allows the free flow of electric charge.
- Elasticity - Measures the stiffness of an elastic material. Elasticity can deformed body and return to its original shape when the forces exerted are removed.
- Elastic limits - Maximum stress that can be applied to a metal without causing plastic deformation that will remain after the load is relaxed to zero.
- Electrode - An electrical conductor used to contact a nonmetallic part of a circuit.
- Electron - A subatomic particle found in all atoms, electrons carry electricity by flowing from one atom to the next in a conductive material.
- Hardness - The property of a material that enables it to resist plastic deformation, usually by penetration. However, the term hardness may also refer to resistance to bending, scratching, abrasion or cutting.
- Kerf loss - The amount of material loss during a cutting process.
- Mask - A patterned layer of material used to prevent the etching of the material directly beneath it.
- Shear stress - Tends to deform the material by breaking rather than stretching without changing the volume by restraining the object.
- Stiffness - The resistance of the elastic deformation of an object that applies to both compression and tension.
- Tensile strength - The maximum stress a material can resist before it starts to elongate.
- Thermal conductivity - The ability to transfer heat within a material without any motion of the material.
- Thermal expansion coefficient - The percentage change in the length of the material per degree of temperature change, heated solid or liquid.
- Yield strength - The minimum stress that leads to permanent deformation of the material.
