AS5958H
This SAE Aerospace Standard (AS) establishes the requirements for externally swaged titanium tube fittings on titanium and CRES tubing with flareless separable fitting for use in hydraulic supply and return aerospace fluid systems up to operating pressure of 5080 psig (35 000 kPa) maximum and an operating temperature range of -65 to +275 °F (-54 to +135 °C). This specification covers a common 5080 psi pressure titanium fitting that may be used for a range of operating pressures up to 5080 psi with different tubing materials and tubing wall thicknesses, and is assembled with the same tooling in accordance with AS5959. The fitting operating pressure is based on the fitting thread pitch. Extra fine pitch for 5080 psi operating pressure and fine pitch for operating pressures 3000 psi and less. Table 12 shows applicable aerospace fitting part number standard and tubing materials and operating pressures.

AMS2759/1H
This specification, in conjunction with the general requirements for steel heat treatment covered in AMS2759, establishes the requirements for heat treatment of carbon and low-alloy steel parts to minimum ultimate tensile strengths below 220 ksi (1517 MPa). Parts are defined in AMS2759. Due to limited hardenability in these materials, there are size limits in this specification.

Aluminum Alloy Forgings and Rolled Rings, 4.4Cu - 0.85Si - 0.80Mn - 0.50Mg (2014-T6), Solution and Precipitation Heat Treated

WIP
AMS4133F
This specification covers an aluminum alloy in the form of die forgings, hand forgings, rolled rings, and forging stock. These products have been used typically for aircraft structural members requiring moderately high strength. Certain design and processing procedures may cause these forgings and rolled rings to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.

Aluminum Alloy Extrusions 7.8Zn - 2.6Mg - 2.0Cuu - 0.10Zr (7068-T6511) Solution Heat Treated, Stress Relieved, and Precipitation Heat Treated

AMS4331A
This specification covers an aluminum alloy in the form of extruded bars, rods, shapes (profiles), and tubing.

These extrusions have been used typically for structural parts requiring a combination of high tensile strength and moderate fatigue strength, but usage is not limited to such applications.

Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; SAE ARP 823 recommends practices to minimize such conditions.

AMS4351A

This specification covers an aluminum alloy in the form of plate products from from 1.000 to 6.000 inches (152.40 mm) in thickness.

7065-T7651 may be used in aerospace applications requiring high strength and good fracture toughness, good resistance to stress-corrosion cracking and to exfoliation corrosion, but usage is not limited to such applications.
