Properties

Ecological

Biodegradable

capable of being broken down especially into innocuous products by the action of living things (such as microorganisms)

Toxicity

an extremely harsh, malicious, or harmful quality

Recyclabe

to reuse or make (a substance) available for reuse for biological activities through natural processes of biochemical degradation or modification

Technological

Recilience

the capability of a strained body to recover its size and shape after deformation caused especially by compressive stress

Elasticity/Plasticity

the capability of a strained body to recover its size and shape after deformation.

Maleabity/Ductility

capable of being extended or shaped by beating with a hammer or by the pressure of rollers 2a

Toughness/Brittlelness

capable of enduring strain, hardship, or severe labor.

Mardness

the quality or state of being hard.

Chemical

Corrosion

the action, process, or effect of corroding 2

Oxidation

the act or process of oxidizing.

Physical

Mechanical

Strengh

Flexion

the act of flexing or bending.

Compression

the process of compressing the fuel mixture in a cylinder of an internal combustion engine (as in an automobile). 3.

Tension

the act or action of stretching or the condition or degree of being stretched to stiffness.

Torsion

the twisting or wrenching of a body by the exertion of forces tending to turn one end or part about a longitudinal axis while the other is held fast or turned in the opposite direction.

Shear

to cause (something, such as a rock mass) to move along the plane of contact.

Optical

Transparent

having the property of transmitting light without appreciable scattering so that bodies lying beyond are seen clearly.

Translucent

transmitting and diffusing light so that objects beyond cannot be seen clearly.

Opaque

blocking the passage of radiant energy and especially light.

Thermal

Welding

unite (metallic parts) by heating and allowing the metals to flow together or by hammering or compressing with or without previous heating.

Fusibility

Capable of being fused and especially liquefied by heat.

Expansion/contraction

the increase in volume of working fluid (such as steam) in an engine cylinder after cutoff or in an internal combustion engine after explosion.

Some materials can conduct heat.

Electrical

Semiconductivity

A semiconductor is a substance, usually a solid chemical element or compound, that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current.

Insulation

The action of warming something

Conductivity

The degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field which causes the flow of current.
