Description
7075 T73 Stress Corrosion Resistant High Strength Aerospace Grade Round Aluminum Bar For Aircraft Structural Components
7075 T73 Stress Corrosion Resistant Round Aluminum Bar
Product Overview

7075 T73 round aluminum bar combines the exceptional high strength of 7075 alloy with enhanced stress corrosion cracking resistance achieved through the T73 overaging heat treatment. This aerospace-grade material is ideal for aircraft structural components, defense equipment, and high-performance engineering applications where both strength and corrosion reliability are critical.

Key Features
  • Enhanced Stress Corrosion Resistance: T73 overaging treatment significantly improves resistance to stress corrosion cracking compared to T6 temper
  • Ultra-High Strength: Tensile strength ≥ 470 MPa, among the highest of all aluminum alloys
  • Excellent Fatigue Resistance: Performs reliably under cyclic loading conditions
  • Good Machinability: Suitable for precision CNC machining operations
  • Aerospace Certified: Meets AMS 4124 specifications

T73 vs T651: Understanding the Difference

The T73 temper involves a two-stage overaging heat treatment that slightly reduces peak strength but dramatically improves resistance to stress corrosion cracking. For aerospace structural applications exposed to corrosive environments or sustained stress, T73 is the recommended temper over T651.

Frequently Asked Questions
Q: What is the advantage of T73 over T6/T651?
A: T73 provides significantly better resistance to stress corrosion cracking while retaining most of the strength of T6 temper.
Q: Is 7075 T73 suitable for aerospace use?
A: Yes, 7075 T73 is widely specified for aerospace structural components requiring both high strength and corrosion reliability.
Q: Can 7075 T73 be anodized?
A: Yes, anodizing is recommended to further enhance surface protection.
Q: What is the minimum order quantity?
A: MOQ starts at 500 KG. Contact us for bulk pricing.
