Abstract
An aluminum-based alloy containing, wt %: Zinc 6.5-7.6 Magnesium 1.6-2.2. Copper 0.8-1.2 Cobalt 0.05-0.2. Zirconium 0.05-0.3 With admixtures of iron up to 0.3 wt %, silicon up to 0.3 wt %, chromium up to 0.05 wt %, manganese up to 0.05 wt %, the balance being aluminum. The alloy may most effectively be used for manufacturing bulky parts of loaded units.
Claims2
A bulky aluminum-based alloy product having high strength and plasticity in short transverse direction and relatively low internal stress, the alloy consisting essentially of, measured as weight percent:
- zinc:
- 6.5 - 7.6;
- magnesium:
- 1.6 - 2.2;
- copper:
- 0.8 - 1.2;
- cobalt:
- 0.05 - 0.2;
- zirconium:
- 0.05 - 0.3;
- and
- the balance comprising aluminum and up to 0.3 weight percent iron, up to 0.3 weight percent silicon, up to 0.05 weight percent chromium, and up to 0.05 weight percent manganese, the bulky product having been subjected to solution treatment with cooling and hardening in boiling water.
