Aluminum 7075 AMS 4078

AMS 4078 is an aerospace material specification covering Aluminum Alloy 7075 plate supplied in a heat-treated condition for high-strength structural applications. Aluminum 7075 plate manufactured to AMS 4078 is commonly cross-referenced to ASTM B209 for plate applications where additional commercial or industrial specification alignment is required.

Aluminum 7075 AMS 4078 plate is known for its exceptionally high strength-to-weight ratio and is widely selected for structural components where maximum mechanical performance is critical, including aerospace and defense applications. The alloy is heat treatable and typically supplied in high-strength tempers to meet demanding structural and fatigue requirements.

Due to its lower corrosion resistance compared to some other aluminum alloys, AMS 4078 material is generally used in controlled environments or applications where protective finishes are applied. Tech Steel & Materials supplies Aluminum 7075 AMS 4078 plate with full material traceability, certifications, and value-added processing to meet customer specifications.
