Aluminum alloys differ in chemical composition and can provide different combinations of strength, corrosion resistance, formability, weldability, fracture resistance, and other properties. Temper identifies the material's designated processing condition, which may reflect annealing, strain hardening, heat treatment, aging, or combinations of treatments depending on the alloy and product. Material certifications, specifications, manufacturing or heat-treatment records, mechanical testing, conductivity or hardness measurements where appropriate, and laboratory characterization can be compared to assess whether the documented alloy and material condition are consistent with what was specified. No single measurement should be assumed to prove a particular temper without considering the alloy, product form, applicable specification, and supporting records.
Aluminum naturally forms a thin oxide film that provides substantial corrosion resistance in many environments, but localized attack can still develop depending on the alloy, exposure, joint configuration, contaminants, coatings or finishes, and contact with other materials. An investigation may examine pitting or other localized corrosion, dissimilar-metal contacts, crevices, drainage or retained moisture, environmental deposits, coating or anodized-finish condition, and the surrounding service environment. Photographs, samples, corrosion products or deposits, material identification, exposure history, and laboratory analysis where appropriate can help assess which corrosion mechanisms are consistent with the observed deterioration.
If sufficiently preserved, a fracture surface may contain features that help locate an apparent crack origin and characterize how fracture progressed. Macroscopic and microscopic examination may identify evidence consistent with overload, fatigue, pre-existing cracking, corrosion-assisted mechanisms, or another fracture process, but the surface should not be interpreted in isolation. Component geometry, alloy and temper, deformation, loading history, welds or other stress concentrations, environmental exposure, and post-fracture damage should also be considered because handling, rubbing, corrosion, or later damage can obscure fracture features.

The effects depend on the aluminum alloy, temper, fabrication operation, and joining process. Welding can create a heat-affected zone in which local mechanical properties differ from the unaffected base material; some work-hardened and heat-treatable aluminum alloys can experience local softening or strength reduction after welding. Forming, machining, extrusion, cutting, and other fabrication processes may instead affect geometry, dimensional conformity, residual stress, surface condition, or local material condition depending on the operation. Drawings, material certifications, weld and fabrication records, dimensional measurements, hardness or mechanical testing where appropriate, and examination of affected regions can help assess whether fabrication or joining contributed to the reported condition.
