Applications: Aluminum 7050 is typically used in aircraft structural parts. Specifications: UNS A97050        7050 Aluminum Plate: 7050 Grade Temper: 7050-0, 7050-T451, 7050-T7651 Bare: AMS 4050, AMS 4201, DMS-2233, BMS 7-323 7050-T7451 Aluminum Plate Per AMS 4050 with USI BAC5439 Class A Mill: Alcoa, Kaiser, Alcan 7050 Aluminum Bar: 7050 Grade Temper: 7050-T74511, 7050-T73511, 7050-T76511 Specification: AMS 4340, AMS 4341, AMS 4342 Chemical Composition Limits Others Weight % Al Zr Si Fe Cu Mn Mg Cr Zn Ti Each Total Minimum 87.3 0.08 - - 2.0 - 1.9 - 5.7 - - - Maximum 90.3 0.15 0.12 0.15 2.6 0.10 2.6 0.04 6.7 0.06 0.05 0.15 Forming The 7050 alloy may be readily formed in either the O temper or the heat treated condition. Welding Welding of 7050 alloy is a problem and should be avoided. Gas tungsten or gas metal arc welding is NOT successful with this alloy. Weld cracking and porosity usually result and any weld joint that is made is much weaker than the parent metal. Heat Treatment Solution heat treat at 890 F. Time at temperature is dependent upon section thickness and the producer of the alloy should be consulted on this as well as quenching rate. Forging The alloy may be forged. However no data is available without consulting the alloy source. Hot Working As with Forging the 7050 alloy may be hot worked but no data is available except from the alloy producer. Cold Working The alloy may be cold formed by conventional means. However bend radii should be generous. Aging A 2 stage heat treatment is used for aging this alloy. First heat to 250 F for 3 to 6 hours (depending on section size) and follow that with 325 F for 15 hours then air cool. Hardening Hardens only by precipitation heat treatment. See "Aging". Other Physical Props Electrical conductivity 40% of copper.   Please call 800-707-6061 or fax to 800-707-3439. You can fill out the RFQ form below. We will get back to you ASAP.
