MatWeb is the database with more materials and information about their properties.
It was one of the first online databases, being very popular among engineers and designers from all over the world and, in many aspects, the most complete. It contains hundreds of possibilities of research criteria through almost one hundred properties (mechanical, physical, thermal, electrical, optical and of production or manufacturing). It includes a large amount of information on thermoplastic polymers, thermoset resins, alloys, metals, ceramics, semiconductors, fibers and other engineering materials.
It is the database that provides more information about a larger number of materials, over 69 thousand. The resulting information is technical and has values for a set of physical, mechanical, thermal, optical and electrical and others properties, which characterize materials in a profound way.
It is the database for material selection that focuses more on technical properties, but the interface could be more flexible. It was designed so that the engineer would be the main user, and it does not include surface and aesthetic properties or any picture for inspiration. It allows many types of search methods, although, when you make an advanced search or a property search, you must have some knowledge, particularly concerning the properties’ values.
MatWeb has also a good “Unite of Measure Converter” and “Weight & Moment of Inertia Calculator” for free. Hence, if you have the premium service, you can also access to a “Metal and Plastic Hardness Converter” and “Glossary of Engineering Material Terms”.
Method of use:
The access to the database is free, however, to access all information and advanced features, such as comparing materials, you have to subscribe to the “Premium” service, which requires an annual subscription that costs US $74.95.
Materials in the database:
The total number of materials is over 69.000.
There are the following “families” of materials: -Metals; -polymers, -ceramics/glass; and composites.
