Here you can find properties for common materials used in mechanical design. This page is a work in progress 🔨
When using our material library, reference the units directory below to know what units you are currently using. (All units are currently in English units, we will create an SI version in the future ⚙️, use our units conversion api or feel free to open a pr in the meantime 😉)
| Property | JSON Key | Units |
|---|---|---|
| Density | den | lb/in^3 |
| Yield Strength | yield_str | psi |
| Ultimate Strength | ult_str | psi |
| Elongation | elongation | % (unitless) |
| Modulus of Elasticity | moe | psi |
| Poisson's Ratio | pr | % (unitless) |
| Maximum Service Temperature | max_service_temp | °F |
| Coefficient of Thermal Expansion | coef_thermal_exp | μin/in |
| Minimum Extruder Temperature | min_extrude_temp | °F |
| Maximum Extruder Temperature | max_extrude_temp | °F |
| Minimum Bed Temperature | min_bed_temp | °F |
| Maximum Bed Temperature | max_bed_temp | °F |
Below is a Python example of how to use the library.
import json
with open('material-properties/carbonsteel.json') as aluminum_properties:
aluminum = json.load(aluminum_properties)
AISI_1020_den = aluminum['AISI_1020']['hot']['den']
A huge thank you to all our contributing engineers!
