EPS 200 vs JIS A9511 EPS — frequently asked

Is EPS 200 stronger than JIS A9511 EPS?

Yes. EPS 200 has a typical tensile strength of 0.45 MPa (0.0653 ksi) against 0.2 MPa (0.029 ksi) for JIS A9511 EPS — about 125% more.

Which is cheaper, EPS 200 or JIS A9511 EPS?

Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.

When should I choose EPS 200 over JIS A9511 EPS?

Pick EPS 200 when strength drives the design, or when the part is bent, formed or impact-loaded. Pick JIS A9511 EPS when weight is the constraint.
