FAQ
Q1: What is the main advantage of 7005 aluminum?
7005 offers excellent weldability, good corrosion resistance, and moderate to high strength, making it ideal for lightweight welded structures, such as bicycle frames, rail transit components, and automotive frames.
Q2: Which tempers are commonly used for 7005?
| Temper | Description | Typical Use |
|---|---|---|
| T5 | Cooled from elevated temperature shaping + artificial aging | Extrusions for moderate strength |
| T6 | Solution heat-treated + artificially aged | Highest strength extrusions & plates |
| T651 | T6 + stress relieved by stretching | Plates & extrusions requiring precise machining |
Q3: Can 7005 aluminum be welded?
Yes. 7005 is weldable using MIG, TIG, and friction stir welding (FSW). Post-weld aging may be required to restore optimum mechanical properties. Avoid fusion welding on very thick sections without proper pre/post-treatment.
Q4: What are the key mechanical properties of 7005?
Tensile Strength: 310–410 MPa (depending on temper)
Yield Strength: 250–350 MPa
Elongation: 8–12%
Hardness (HB): 120–150
Fatigue Strength: Moderate, suitable for structural frames
Q5: What standards are followed for 7005 supply?
EN 485 / EN 573 – plates & sheets
EN 755 – extrusions & tubes
ASTM B209 / ASTM B221 – international plates & extrusions
Custom project standards available on request
Q6: What forms and sizes can 7005 be supplied in?
Plates & sheets: 1–200 mm thickness, 600–2500 mm width
Extruded profiles: up to 450 mm width, hollow or multi-cavity
Tubes: OD 10–200 mm, wall thickness 1–20 mm
Bars / rods: Ø8–150 mm, lengths 2–6 m
Welded structural frames: custom dimensions up to 8 m long
Q7: Can 7005 aluminum replace steel in structural components?
Yes. It is lightweight yet strong, ideal for applications requiring weight reduction with sufficient structural integrity, such as rail transit frames, bicycle frames, and vehicle chassis.
Q8: What inspection and quality assurance is provided?
Chemical composition verification
Mechanical testing (tensile, yield, elongation, hardness)
Ultrasonic testing (UT) for plates optional
Dimensional and flatness inspection
Third-party inspection: SGS / BV / TUV
Full documentation: MTC 3.1 / 3.2, UT report, CO/ROHS/REACH
Q9: What is the typical delivery time?
Stock items: 3–10 days
Custom extrusions or profiles: 15–30 days
Large welded structures: 20–45 days
Q10: Can 7005 aluminum be machined for precision components?
Yes. T651 plates and extrusions are ideal for CNC machining, including milling, turning, drilling, and surface finishing. Stress relief may be needed for large sections to maintain dimensional stability.
