Intact.design provides many material options, organized into five main groups: ferrous metals, non-ferrous metals, non-metals, 3D printed plastics, and engineering plastics.

As a very brief overview, ferrous metals contain iron and are usually magnetic. They are used for their high tensile strength and durability. Non-ferrous metals are nonmagnetic and tend to be lighter and more malleable than ferrous metals. Non-metals do not exhibit characteristic properties of metals such as hardness and conductivity. Engineering plastics are similar to 3D printed plastics, however in general they tend to be harder and more durable.

For a list of all the materials with their properties, download this excel sheet. In the Excel sheet, there are several lines to understand

1. Material name
2. Category: Ferrous metal, non-ferrous metal, non-metal, 3D printed plastic, engineering plastic (Organized by category in Intact.design)
3. Failure criterion: a way to measure how and under what conditions a material will fail. Materials either fracture (brittle failure) or yield (ductile failure). There are several failure criterion methods for each type of failure.
4. Density: defined by mass/volume
5. Elastic modulus: derived from the linear (elastic) region of the stress-strain curve; a measure of a material’s resistance to being deformed when a force is applied to it.
6. Poisson’s ratio: negative ratio of lateral strain to longitudinal strain.
7. Yield Strength: stress at which a material begins to deform plastically
8. Tensile Strength: the maximum stress a material can withstand before breaking while being pulled apart
9. Compressive strength: the maximum stress a material can withstand before breaking when being compressed
