One, ASTMB80005 (2011) and the national standard of the national standard AA-8000 of the r aluminum alloy chemical composition.
Two, tensile strength: 98Mpa-159Mpa.
Three, the extension rate: 10% and above.
Four, the electric conductivity: 61%IACS and above (20 degree DC resistance 0.028264 and below).
Five, material density: AA8000 aluminum alloy density 2.71g/cm3 and above.
Six, 100 hours of compressive creep test: test conditions, test temperature of 90 degrees, the test pressure stress 76Mpa, 100 hours of examination time, then watch conductor aluminum alloy creep curve and the copper conductor creep curve comparison.
Only these criteria for the evaluation of the provisions of the same time (Note: it is also met), is a qualified conductor of aluminum alloy material.
