Description / Abstract: This specification covers the requirements for wrought aluminum alloy sheet for heat shields. This specification is applicable only to non-age hardenable aluminum alloys. Non-age hardenable aluminum alloy sheet supplied to the specification shall be formable by conventional cold stamping processes.

Non-age hardenable aluminum alloy sheet supplied to this specification can be utilized to fabricate single monolithic sheet heat shields, multilayer sheet heat shields, or the skins of composite heat shield assemblies consisting of thermal barrier textile. Thermal barrier textiles are covered by separate material specifications.

Additional requirements or agreements shall be specified by each region (e.g., GMNA, GME, GMLAAM, GMAP, etc.)

Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Material Description. The material designation is defined by the GMW base metal specification number, aluminum alloy series number (1000, 3000, or 5000), a letter to differentiate specific aluminum alloy grades, a temper designation, and, if applicable, a designation for surface texture.

Symbols. Not applicable.

Applicability. Typical applications include underbody heat shields and exhaust system heat shields.
