physical properties

definition

Fusibility

The ability of a material to be fused or converted from a solid to a liquid/molten state usually by heat.  Good fusibility is an essential property for metal being cast.

Density

The mass of the material in a standard volume of space

(relative density is to that of pure water at 4˚C)

Chemical resistance

The ability for a material to resist damage by chemical reaction or solvent action

Corrosion/degradation resistance

The ability of the material to withstand environmental attack and decay

Impervious to gases

The material is not able to be penetrated by gases such as oxygen and carbon dioxide.  Sealed containers can be air tight.

Non-toxic

A product, substance or material that will not cause adverse health effects, either immediately or over the long term

Pigment coloured

Material is coloured at the point of manufacture.  Colour goes right through material
