FAQ
Q1: What are the main advantages of Aluminum 7075?
7075 offers very high strength, excellent fatigue resistance, good machinability, and strong performance-to-weight ratio. It is one of the strongest commercial aluminum alloys, widely used in aerospace and high-load structural parts.
Q2: What is the difference between 7075-T6 and 7075-T651?
Both have similar strength, but T651 is stress-relieved by stretching, making it more stable for machining and preventing deformation in thick plates.
T6: sheet, bar
T651: plate (most common)
Q3: When should I choose T73 or T74 temper instead of T6/T651?
Use T73/T74 when your project requires superior stress corrosion cracking (SCC) and exfoliation corrosion resistance.
T73 has the best corrosion resistance, while T74 provides a balance of strength and SCC resistance.
Q4: What standards do you follow when supplying 7075 aluminum?
Common export-grade standards:
ASTM B209 (plates, sheets)
ASTM B211 (bars, rods)
ASTM B221 (extruded products)
AMS 4045 / AMS 4078 / AMS 4124
EN 485 / EN 573
Q5: Do you provide ultrasonic tested (UT) plates for aerospace use?
Yes. We supply 100% UT-tested 7075 plates according to AMS-STD-2154, Level A/B requirements.
Q6: What is the maximum thickness of 7075 plate you can supply?
We can supply 6–300 mm standard, and thicker customized sizes on request.
Q7: Can 7075 aluminum be welded?
7075 has poor weldability and typically is not recommended for fusion welding. Mechanical fastening or friction stir welding (FSW) is preferred in engineering applications.
Q8: What machining services are available?
We offer CNC milling, sawing, turning, surface machining, and customized shapes. T651 plates are widely used for precision machining due to high stability.
