Aluminium Alloy 1100 is a popular grade of aluminium for general sheet metal work where moderate strength is required. Aluminium Alloy 1100 is known for its excellent corrosion resistance, high ductility and highly reflective finish.

| Mechanical properties are those specified by ASTM B209M−14 for alloy 1100 in H14 temper, for the sheet thicknesses we stock. Alloy 1100 has no table in EN 485-2, so B209 is the governing specification here. Brinell hardness is not specified by B209 and is therefore not listed; it is typically around 32 HB, for information only. Sheet of 40 mm falls outside the H14 thickness range covered by the specification. Certificates to EN 10204-3.1 are available on request. | |||
