Super High Strength Aluminum Alloy
Mechanical Properties Comparison between Rapid Solidification and Conventional Castings:
Material Tensile Strength MPa Yield Strength MPa Hardness HB Elongation %
Conventional casting 7075 480-560 430-470 150 8%-9%
Rapid solidification 7075 600-730 580-670 200 10-12%
Physical Properties Comparison:
7000 Aluminum Alloys Grain Size Segregation Degree Yield Ductility Stress Corrosion Resistance
Conventional casting 7075 80-300μm generate macro segregation 40-50% poor ductility fair
Rapid solidification 7075 3-25μm no macro segregation 70-80% high ductility 3-5 times of common 7000 aluminum alloys
