Aluminum Alloy, Rolled or Forged Rings 6.3Cu - 0.30Mn - 0.18Zr - 0.10V - 0.06Ti (2219-T351, 2219-T352) Solution Heat Treated and Mechanically Stress Relieved - UNS A92219

Annotation

Purpose

This specification covers aluminum alloy rolled or forged rings up to 6 inches (152 mm) which are produced and shipped in the –T351 or –T352 temper and are artificially aged to the –T82 temper prior to being put into service.

Application

These rings have been used typically for structural applications requiring good fusion weldability, a combination of good strength and resistance to stress-corrosion cracking, and for parts requiring good stability during machining, but usage is not limited to such applications.

Certain design and fabrication procedures may cause these rings to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.

Classification

Rings covered by this specification are classified by type of mechanical stress relief as follows:

Type 1 - Stress relieved by stretching (2219-T351)

Type 2 - Stress relieved by compression (2219-T352)

Either type may be supplied, unless a specific type is ordered.
