Click Here or Scroll Down For Help!  Metal and Alloy Composition Search

Need some help with this search? Try our Flash demo!  Locate alloys based on their constituent elements!

Choose an Element (Required)
Scroll down the list below and highlight an element, then set composition limits on that element. You need enter only a minimum or maximum value.

% Min    % Max

Choose a Second Element (Optional)
Scroll down the list below and highlight a second element, then enter limits for it.

% Min    % Max

Choose a Third Element (Optional)
Scroll down the list below and highlight a third element, then enter limits for it.

% Min    % Max

Choose a Search Category (Optional)
If you wish to restrict your search to a category of metals, scroll down the list below and highlight that metal category. The list contains all current categories of Ferrous Metals, Nonferrous Metals, Superalloys, and Pure Metals in the database.

Choose to Return Materials that Match at least 1 or All of the Component Ranges (Optional)
Click on one of the radio buttons below. The default option is All component ranges.
At least 1 component range
All component ranges (default)

Submit the Query (Required)
Click on the Find button below to submit the query.


Instructions: Select up to three elements (be sure to enter a minimum value, a maximum value, or both), choose a metal search category (optional), select whether the metal must match at least one or all of the search criteria (all is the default), and click the 'Find' button. A list of list of descriptive names of alloys will be returned, each of which links to the full datasheet. More detailed instructions and examples.


  • The MatWeb database contains the full limiting composition of an alloy, including minimum and maximum values specified for each element, when available. Values are almost always based on the Weight Percentage of each constituent element. If any part of the composition range overlaps with any part of the range that you enter in a search above, then a match is established. For example, if you are searching for alloys with a chromium content of 20-25%, then one of the alloys returned by MatWeb will be Nimonic Alloy PK33 (with a chromium content between 16-20%).

  • Please note that the full chemical composition range of an alloy is not always available; in such cases MatWeb reports the nominal composition. For example Special Metals has provided MatWeb with limiting composition ranges for Inconel 718 but only the nominal composition of Inconel alloy MA 754.

  • MatWeb has calculated numerical values for constituent elements that are reported as the 'balance' after all other elements are totaled. For example, the iron content of Invar 36 listed in MatWeb is 63%, since 63% is the remainder after the nickel and the minor components have been subtracted from 100%. Please note that in some cases, these remainder values may fall outside of the composition of the actual alloy.
