Keep alloy, temper, product form and test condition together when comparing properties.
Begin with the full condition
A grade number describes the alloy designation. It does not establish the final mechanical condition. Record the temper, manufacturing route and the actual product form before comparing data. A tube property should not silently become a sheet property.
Typical values and limits
Typical properties describe reference behaviour. Minimum specification values define a stated lower bound for a particular condition. Neither is automatically a structural design allowable. A supplier certificate and the governing purchase specification establish the delivered material requirements.
Thickness and test basis
The Hydro extrusion tables tie mechanical properties to the section from which the tensile specimen is taken. Keep that thickness condition with the value. Where the source gives a tensile specimen diameter but not the material thickness range, report that limitation explicitly.
Resolve conflicting values
Different values can reflect different tempers, forms, test temperatures or reporting conventions. Compare those conditions before declaring a conflict. If a unit is inconsistent or the condition cannot be established, withhold the property and request another source.

Detect mixed comparison bases
UACJ’s plate comparison explicitly places typical aluminium properties beside lower-limit steel properties. Rio Tinto’s foundry tables add casting method and temper. These examples show why a comparison must preserve value basis and specimen condition: putting numbers in adjacent columns does not make them equivalent. Before using a table, label each row as a supplier reference, requirement or test result and retain missing conditions as unknowns.
