7055 Aluminum Sheet Plate for Aerospace
7055 aluminum sheet plate has the characteristics of high strength, high corrosion resistance, high impact, widely used in the field of aerospace. Mainly used as wing, fuselage, engine housing, landing gear and engine room interior parts.
MESSAGE
Overview
7055 aluminum sheet plate is an ultra-high-strength Al-Zn-Mg-Cu heat-treatable alloy, recognized as one of the highest-strength aerospace aluminum alloys. It features extremely high tensile strength, excellent fracture toughness, fatigue resistance, and corrosion resistance, especially in the T7751 stress-relieved temper. And it is widely used in wings, fuselages, landing gear, and engine parts to achieve lightweight, high safety, and fuel efficiency.
Specification
Alloy: 7055
Temper: T7751
Thickness: 0.5-600mm
Width: Max 2650mm
Length: Max 8000mm
Feature
1.High Strength: The strength of the 7055 aluminum alloy sheet plate is approximately twice that of traditional aerospace aluminum alloys, enabling it to withstand higher loads and more severe working conditions.
2.Good Corrosion Resistance: Its corrosion resistance is several times that of ordinary aluminum alloys, allowing for long-term use in harsh environments.
3.Good Machinability: It can be processed using traditional metalworking techniques such as milling, drilling, cutting, and bending, facilitating manufacturing and processing.
4.High Impact Resistance: The impact resistance is 30-50% higher than that of ordinary aluminum alloys.
5.Good Weldability: It can be connected by conventional welding methods, facilitating manufacturing and maintenance.
6.Lightweight: Despite its high strength, its density is still lower than many other metals, making it an ideal material for the aerospace industry.
Application
1.Aerospace Structural Components: Used for manufacturing wings, fuselages, engine housings, landing gear, and cabin interior parts, etc.
2.Structural Parts of Fuselage: Such as fuselage shells, bottom cover plates, porthole frames, etc.
3.Wing Body Joints: Used for manufacturing structural components connecting the wing to the fuselage and structural components connecting horizontal and vertical stabilizers.
4.Landing Gear: Used for manufacturing structural components of landing gear, such as struts, connecting plates, and protective covers.
5.Engine Parts: Used for manufacturing aircraft engine parts such as hoods, intakes, fuel tanks, and turbine blades.
