Highlights

497 records plus a curated set of EN steel grades, bolt classes, concrete, AM alloys and polymers
Property-vs-property log charts with the Pareto front and ten derived performance indices
Compare up to eight materials side by side, or rank them against weighted objectives
Every value read at the temperature you set; missing data shows as missing, not as zero
The same library supplies the material fields in the other Twinsys tools

A question it answers

Which alloy gives me the best stiffness per unit mass, stays under 3 g/cm³, and is still usable at 200 °C?

What you put in

Free-text search; family and dataset filters; a READ TEMPERATURE that governs when every temperature-dependent value is evaluated; hard constraints as minimum and maximum on any property; weighted objectives with a maximise or minimise sense; and a selection of up to eight materials for comparison.

What you get

Browse table with per-column coverage counts so an empty cell reads as missing data rather than zero; property-versus-property chart coloured by family with the Pareto front drawn and ten derived performance indices selectable as axes (specific stiffness for tie, beam and panel loading, specific strength, thermal shock resistance and others); comparison table over the union of the selected materials' properties; and a ranked selection list shown alongside the list of materials that were EXCLUDED, each named with its reason.
