Find engineering materials by grade, chemical composition or intended use. Materials Handbook brings steel, copper and aluminum references together in one offline catalog. SEARCH BY GRADE Search familiar designations and aliases, including 65G, 60C2, Y8, SPCC, C45 and 6061. View composition ranges, typical applications and technical notes. COMPARE MATERIALS See available cross-standard composition matches directly by grade. Compare element ranges side by side. For supported cases, review proposed replacements by application, with the conditions that must be met and the situations where substitution is unsuitable. FIND MATERIALS FROM YOUR REQUIREMENTS Enter an application, one or more chemical contents, or a combination of both. Composition searches accept individual values and ranges. Incomplete data is clearly distinguished from confirmed overlap. MADE FOR EVERYDAY REFERENCE Search the catalog without an internet connection. No account is required. The app includes banner advertising. The catalog is a reference aid, not a certification of interchangeability. Before specifying or substituting a material, verify the applicable standard edition, product form, mechanical properties, heat treatment and service conditions. Coverage varies by grade and standard.
