Here you can find properties for common materials used in mechanical design. This page is a work in progress

Units Directory

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. In the meantime, you can use our units conversion api.

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

Code Example

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']
