MatWeb's database of material properties includes thermoplastic and thermoset polymers such as ABS, nylon, polycarbonate, polyester, and polyolefins; metals such as aluminum, cobalt, copper, lead, magnesium, nickel, steel, superalloys, titanium and zinc alloys; ceramics; plus a growing list of semiconductors, fibers, and other engineering materials. MatWeb is still freely available and does not require registration. However, advanced features are only available to Registered and Premium users. MatWeb users can find materials property data with several powerful tools:
There are also convenient drop-down lists of polymer trade names, polymer manufacturers, and metal and alloy UNS Numbers. The quick Search (located at the top right of each page) allows you to enter any word or phrase to search on, such as the common name, product name, name of the manufacturer, or materials specifications such as ASTM number or UNS number. The Sequential Search link in the navigation bar, available to registered and premium users, is our most powerful search, and combines the property, composition, and text searches into a single iterative process.
