About AlloySense
A composition-based alloy identification tool built for the people who actually use spectrometers.
What AlloySense is
AlloySense is a composition-based alloy identification tool built for metallurgical laboratories, foundries, and quality control engineers. It matches elemental composition data — typically from an optical emission spectrometer — against a database of alloys spanning eight base materials: iron, copper, aluminum, nickel, titanium, magnesium, cobalt, and zinc. The underlying data has been compiled from a range of technical sources, including material standards, supplier datasheets, and established engineering references.
How it works
The fastest way to use AlloySense is to enter your measured composition and let the matching engine return a ranked list of the closest grades. For each match, the tool shows an element-by-element breakdown so you can see exactly which values fall inside a grade's specified range and which fall outside. This transparency is intentional — a grade match is only useful if you can verify the reasoning behind it.
Grade designations and equivalents
Each alloy in the database is identified by its most widely recognised designation, with equivalent or comparable grades from other standards noted where applicable. It is worth remembering that equivalents across designation systems are rarely identical. A grade listed under AISI, EN, DIN, and JIS may differ slightly in permitted element ranges or minor additions, but is usually close enough to be treated as interchangeable for most practical purposes.
How composition data is stored
Composition in AlloySense is stored as minimum and maximum ranges per element, reflecting how real specifications are written. Where a source provides only a nominal or aim composition rather than a full range, this is noted — since a single value carries less certainty than a defined range. Mechanical and physical properties such as tensile strength, hardness, and elongation are reported alongside each grade where available, though these depend heavily on heat treatment and processing condition and should be read as representative rather than absolute.
Our commitment to accuracy
Our priority is accuracy you can defend. Each record is intended to be traceable to its source, and the database is reviewed and expanded over time. If a value ever looks wrong against your own reference, we want to hear about it.
