Wrought alloys H112 and T4 treated have the proof stress ratio σ0.2/σB little greater than 0.7 and ones T6 treated have the ratio little smaller than 0.9. A linear relationship is found between the proof stress ratio and the n-value. The elongation determined from the strain distribution in the specimen considerably agrees with the uniform elongation calculated by Barba's law, but the value measured from the change of section-area of the specimen disagrees. Brinell hardness rises with increase of the indenting load and attains the maximum at about d/D=0.4 (d: impression diameter, D: ball diameter). HB of the alloys of high n-value remains constant with increase of the load, but HB of the alloy having low n-value lowers with increase of the load. The test loads 1000kg and 1500kg are recommended rather than 500kg respectively for most of aluminum alloys and for ones having HB more than 80 to obtain the maximum hardness.
