By fast the most complete freely accessible material properties database. For metals, plastics, ceramics, and composites, although plastics is where it really shines. Many datasheets also included. Typically:

Physical Properties such as
- Density
- Linear Mold Shrinkage
- Melt Flow index
- Ash %
Mechanical Properties such as
- Hardness, Rockwell R
- Tensile Strength at Break
- Tensile Strength, Yield
- Elongation at Break
- Elongation at Yield
- Tensile Modulus
- Flexural Strength
- Flexural Modulus
- Izod Impact
Thermal Properties
- Deflection Temperature at 0.46 MPa (66 psi)
- Deflection Temperature at 1.8 MPa (264 psi)

Already a lot without any registration. A must-have for numerical simulation.

Disciplines: Materials science, Mechanical engineering, Plastics engineering, Aerospace, Product design, Manufacturing.

MatWeb Material Properties Database compared with Granta Selector, Ansys Granta EduPack and Matmatch
MatWeb Material Properties Database	Granta Selector	Ansys Granta EduPack	Matmatch
Coverage: MatWeb offers over 185,000 datasheets for metals, plastics, ceramics and composites, and all can be viewed for free. Thermoplastics are where it is strongest.	Coverage: Granta Selector uses MaterialUniverse, with technical, economic and environmental data for thousands of engineering materials, which is a curated and smaller but comparable set.	Coverage: EduPack is a teaching resource with a database of materials and process data split into three levels, from pre-university to postgraduate.	Coverage: Matmatch is a Munich-based database that compares metals, ceramics, polymers and composites by physical, chemical and thermal characteristics.
Data provenance: Many entries are manufacturer datasheets or are submitted by suppliers, so values depend on the source and should be read with the test conditions.	Data provenance: Data is drawn from design data, manufacturer datasheets, standards information and test data, and 2026 R1 updated polymers from UL Prospector.	Data provenance: The data is built for education and for teaching selection methods, not for qualifying a production material.	Data provenance: Its in-house materials scientists compile and verify data, using licensed academic and corporate databases to check supplier information, according to its launch announcement.
Search and export: Free search is limited to 1,000 results. Premium (paid subscription) adds 10 search criteria, 20 datasheets per comparison, CSV and CAD export and graphing.	Search and export: The software filters on limits, plots property charts, finds similar materials and exports to Ansys tools and third-party CAE, and it adds Eco Audit and part cost estimation.	Search and export: Selection tools, Eco Audit and teaching material are included, and the full version adds Advanced Data and the Synthesizer tool.	Search and export: Search, comparison by properties and supplier information are online, no installation.
Licence and cost: Free viewing, registered use and a paid annual Premium plan.	Licence and cost: Commercial desktop licence, no public price, demo on request.	Licence and cost: Licensed to educators and institutions. Price and terms are not stated on the product page.	Licence and cost: Described as free to use when launched. Current conditions should be checked on the site.
When to choose it: Choose it for plastics datasheets, quick property values and inputs for a simulation, with no sign-up for viewing.	When to choose it: Choose it for engineering projects needing selection charts, cost, sustainability and simulation export.	When to choose it: Choose it for university courses on materials selection.	When to choose it: Choose it for supplier-linked data on commercial grades.
