aerospace vehicle structure.
Quickly details.
- Alloy: 7049:
- Temper: T73,T7351,T7451,T7651.
- 7049 - T73 is a kind of stress corrosion crack resistance excellent high strength aluminum alloy. People have used it to production die forgings and free forging. Ingredients: physical constants: zinc proportion of 7.2 7.8 7.2 2.0 2.9 g/cm ~ 3 magnesium smelting temperature 477-627 ℃.
- 7049 - T73 forgings can be compared with 7075 - T73 of stress corrosion resistance, and the strength is the 7075 - T73 high 10-15%. Because of 7049 - T73 alloy elements, processing and heat treatment very well integrated together. To its high strength, and stress corrosion resistance. To increase the stress corrosion
- strength, less distortion.
- Max diameter: 1320mm.
- Max length : 7500mm.
- The density: 2.83g/cm3
Features:
Large specification :the produced billetφ1320mm is the largest billet in the world.
The max : weight of the billet up to 12.5 ton.
High purity : low hydrogen, low dross, low alkali content inside the ingot .
high-homogeneity : composition & organization, Small degree of segregation.small grain
size difference between core and surface.
Fine grain size.

Characteristics of 7049 aluminum.
- 7049 is a high strength heat treatable alloys,
- Hhigh strength and resistance to spalling corrosion and stress corrosion cracking resistance performance.
- Often used in aircraft structures used in thick plate extrusion, free forging and die forging parts.
- Manufacturing is required for this part of alloy: spalling corrosion and stress corrosion cracking resistance, fracture toughness and fatigue resistance are strong.
Package: wooden pallet.
