7075 Aluminum Plate
Sheet
HWALU 7075
aluminum plate sheet is one of the highest strength aluminum alloys available.
It has good machinability and an excellent strength to weight ratio, and it is a
popular materials in applications where strength is extremely critical. 7075
aluminum plate sheet is often used for highly stressed parts, and has average
corrosion resistance, improved resistance is normally obtained by cladding
parts. Welding is generally not recommended. 7075 is a heat treatable grade of
aluminum, and sometimes used in place of 2024.
HWALU 7075
aluminum plate sheet have application throughout aircraft and aerospace
structures where a combination of high strength with moderate toughness and
corrosion resistance are required. Typical applications are alclad skin sheet,
structural plate components up to 101.6mm in thickness and general aluminum
aerospace applications.

plate sheet
Two sides
cladding, nominal cladding thickness is 4% on gauges under 1.57mm, 2.5% on
gauges over 1.57mm. Property values for one side clad materials are
similar.
HWALU 7075
aluminum plate sheet offer moderately good strength toughness relationships and
are the standard of comparision for more recent 7*** series alloy developments.
Alloy 7075 aluminum plate sheet are not offered with guaranteed minimum fracture
toughness values.
Corrosion
resistance
HWALU alloy
7075 aluminum plate sheet has been thoroughly evaluated for corrosion resistance
of atmospheric weathering, stress-corrosion cracking and exfoliation in all
currently available tempers. These values have been used as a standard for
comparision in the development of more recent high strength aerospace alloys.
Within the 7*** series of alloys, resistance to general corrosion attack,
exfoliation improves HWALUficantly in the overage tempers(T7 type) compared with
peak strength temper( T6). Generally, the T76 type temper is considered the
exfoliation resistant temper, while the T73 type temper is considered the SCC
resistant temper. It should be noted that T73 is as resistant to exfoliation as
T76, but at lower strength levels. For applications where good surface
appearance is required or in corrosive environments, alcald 7075 plate sheet are
recommended.
Thermal
treatment
Many heat
treatments and heat treating practices are available to develop optimum
strength, toughness and other desirable characteristics for proper application
of alloy 7075 aluminum plate sheet products.
