FAQ
Total weight = volume × density. Aerospace and aviation drive mass minimization — material density and geometry both factor.
Aluminum is ~35% the density of steel. Equivalent strength aluminum part typically 50-60% of steel weight.
Magnesium AZ91D at 1.81 g/cm³. ~33% lighter than aluminum. Used in cameras, automotive, aerospace.
Tungsten at 19.3 g/cm³. Used for counterweights, radiation shielding, high-density inertia applications.
0.9 (PP) to 2.2 (PTFE). Most engineering plastics 1.0-1.5 g/cm³ range.
Yes — CAD provides volume; multiply by density. We provide weights with quotes.
