7050 Aluminum Plate & Extruded Bar
Arch Metals supplies 7050 aluminum plate and extruded bar from Dallas, Texas, for aerospace, defense and precision machining customers across Texas and the surrounding states. 7050 is a high-strength alloy built for thick sections. We supply it mainly as 7050-T7451 plate and 7050-T74511 extruded bar, with certified material and saw cutting to your dimensions. Sizes vary by temper and form, so request a quote and we’ll confirm current availability.

Thickness, diameter and length availability changes with mill supply. Send us your sizes through our quote request form and we’ll confirm stock, lead time and pricing.
7050 Aluminum Tempers and Specifications
- 7050-T7451 plate (AMS 4050, ASTM B209): solution heat treated, stress relieved by stretching and overaged. It keeps high strength through thick sections with good stress-corrosion and exfoliation resistance.
- 7050-T74511 extruded bar (AMS 4342, ASTM B221): the extruded equivalent of T7451, stretched with minor straightening allowed.
- 7050-T73511 extrusions (AMS 4341): a more fully overaged temper for maximum stress-corrosion resistance.

Typical Properties of 7050-T7451 Aluminum
- Ultimate tensile strength: about 76 ksi (524 MPa)
- Yield strength: about 68 ksi (469 MPa)
- Elongation: about 11%
- Density: 0.102 lb/in³ (2.83 g/cm³)
- Chemistry: aluminum alloyed with zinc, magnesium and copper, plus zirconium for grain control
These are typical values for 7050-T7451 plate. Guaranteed minimums vary by specification, temper and thickness, so check the governing spec or your mill cert for design values.
Why Aerospace Machinists Choose 7050 Aluminum
7050 was developed to keep its strength in thick plate, where 7075 aluminum loses properties at the center. It is less quench sensitive than 7075 and offers better fracture toughness and stress-corrosion resistance, which makes it the standard choice for large monolithic aircraft parts. For thinner, cost-sensitive work, 6061 aluminum bar or 2024 aluminum bar may be a better fit. Common uses for 7050 include:
- Aircraft bulkheads, frames and wing spars
- Fuselage and wing structural components
- Large machined monolithic parts
- High-strength fittings and landing gear components
- Tooling and molds that need thick sections
7050 Aluminum FAQs
What is the difference between 7050 and 7075 aluminum?
7075 is strongest in thinner sections. 7050 keeps its strength, toughness and stress-corrosion resistance much better in thick plate, so it is preferred for large machined aircraft parts. See our 7075 aluminum bar page for comparison.
What does the T7451 temper mean?
T74 means the alloy is solution heat treated and overaged for better corrosion resistance. The 51 suffix means it was stress relieved by stretching, which keeps plate stable when it is machined.
Can you cut 7050 plate to size?
Yes. We saw 7050 plate and bar to your dimensions, so you only pay for the material you need.
