Abstract
Novel aluminum alloys are provided for use in an impact extrusion manufacturing process to create shaped containers and other articles of manufacture. In one embodiment blends of recycled scrap aluminum are used in conjunction with relatively pure aluminum to create novel compositions which may be formed and shaped in an environmentally friendly process. Other embodiments include methods for manufacturing a slug material comprising mixtures of aluminum alloys for use in the impact extraction process, a container manufactured using the aluminum alloy in an impact extrusion process, and the container, wherein the material of the container is the aluminum alloy.
Claims20
A metal container, comprising:
- a body, comprising:
- a diameter between about 0.86 inches and about 3 inches;
- a height between about 2.3 inches and about 11 inches;
- and
- a wall with a thickness of between about 0.003 inches and about 0.16 inches;
- and
- wherein a material of the body comprises:
- at least about 97.56 wt. % Al;
- between about 0.07-0.46 wt. % Si;
- between about 0.22-0.44 wt. % Fe;
- between about 0.04-0.65 wt. % Mn;
- between about 0.02-0.73 wt. % Mg;
- between about 0.02-0.05 wt. % Ti;
- at most about 0.15 wt. % impurities;
- and
- a balance comprising at least one of Cu, Zn, and Cr.
An aluminum container, comprising:
- a cylindrical body extending upwardly from a closed bottom end, the cylindrical body comprising:
- a dome at the closed bottom end;
- a diameter between about 0.86 inches and about 4.3 inches;
- a height between about 1.8 inches and about 11 inches;
- and
- a thickness of between about 0.003 inches and about 0.16 inches;
- a neck extending from an upper end of the cylindrical body;
- a curl at an upper end of the neck, the curl defining an opening and configured to receive an aerosol valve, wherein the aluminum container is formed of an aluminum alloy comprising:
- at least about 97.56 wt. % Al;
- between about 0.07-0.18 wt. % Si;
- between about 0.22-0.44 wt. % Fe;
- between about 0.015-0.2 wt. % Cu;
- between about 0.22-0.65 wt. % Mn;
- between about 0.06-0.20 wt. % Mg;
- no more than about 0.04 wt. % Zn;
- no more than about 0.045 wt. % Cr;
- and
- between about 0.02-0.05 wt. % Ti,
- wherein the aluminum alloy is formed by combining between 40-90 wt. % of a first aluminum alloy and between 10-60 wt. % of a second aluminum alloy, wherein neither the first aluminum alloy nor the second aluminum alloy are recycled, and wherein the cylindrical body is formed by an impact extrusion process.
