Product catalog summary
Typical Applications
  • High-stressed components for commercial and military aircraft.
  • Rolling stock for machine parts and tools, particularly for rubber and plastics.
  • Fixings such as screws, nuts, bolts, and rivets.
  • Nuclear applications.
Product Description

L95 aluminium alloy is a high-strength plate product primarily used in the aerospace sector. It is typically supplied in T651 temper, offering high fatigue strength. Cladding with 7072 is recommended for enhanced protection against stress corrosion cracking.

Key Features
  • Very high strength and fatigue resistance.
  • Corrosion protection is recommended.
  • Commonly supplied in T651 temper.
Chemical Composition

The alloy consists of Zinc (5.10-6.40%), Magnesium (2.10-2.90%), Copper (1.20-2.00%), and other elements in smaller quantities, with Aluminium as the balance.

Technical DatasheetAluminium Plate Service. Quality. Value. Typical Applications Key features: • High stressed components for commercial & military aircraft • Rolling stock for machine parts and tools (for rubber and plastics) • Fixings including screws, nuts, bolts & rivets • Nuclear applications • Very high strength alloy • Very high fatigue strength • Corrosion protection recommended • Most common temper for L95 is T651 Related material specifications: Product Description L95 aluminium alloy is a very high strength plate product which is supplied to the aerospace sector in both commercial and military markets. Normally supplied as T651 temper, the alloy also benefits from a very high fatigue strength. The material may be clad with 7072 which will provide better protection against stress corrosion cracking (SCC). Aluminium alloy L95 - 7075 is covered by standard BS 2L95 (1971). BS2L95 (1971) was superseded by BS EN 2126 on 15 October 1996. Corrosion protection recommended for outdoor atmosphere.
