Principal Design Features
|
|
7175 is a high strength, heat treatable, forging alloy. It has an excellent combination of toughness and strength, similar to 7075 alloy except that the 7175 version has superior toughness and tensile strength.
|
|
|
Applications
|
|
Typical applications include machined fittings as used in the aircraft industry.
|
|
|
Machinability
|
|
The alloy is machinable. However no specific comments are available. Consult the supplier.
|
|
|
Forming
|
|
This is basically a forging alloy and thus is formed by die or hand forging.
|
|
|
Welding
|
|
No information available. Consult the alloy supplier.
|
|
|
Heat Treatment
|
|
The alloy is heat treatable. Consult the supplier for details.
|
|
|
Forging
|
|
This is basically a forging alloy. For data on forging temperature range consult the alloy supplier.
|
|
|
Hot Working
|
|
Hot working, as with forging, may be done with this alloy. Consult the supplier for details.
|
|
|
Cold Working
|
|
Cold working may be done by conventional methods, again allowing generous bend radii as with 7075 alloy.
|
|
|
Annealing
|
|
No data available. Consult the alloy supplier.
|
|
|
Aging
|
|
This is an age hardenable alloy. Consult the supplier for aging treatment details.
|
|
|
Tempering
|
|
Not applicable.
|
|
|
Hardening
|
|
Hardens by means of heat treatment or by cold work.
