Title: Extrusion product made of aluminum/aluminum alloy matrix composite and a process of forming the extrusion product

Brief Patent Description - Full Patent Description - Patent Claims

The Patent Description & Claims data below is from USPTO Patent Application 20080240976, Extrusion product made of aluminum/aluminum alloy matrix composite and a process of forming the extrusion product.

1. A process of making an extrusion product with matrix composite aluminum alloys comprising acts of: providing at least two different aluminum alloys; selecting one of the at least two aluminum alloys to be a core; selecting the rest of the at least two aluminum alloys to be at least one hollow covering and mounted around the core to form a billet; heating the billet to become deformable; and extruding the billet to form the extrusion product with matrix composite aluminum alloys.

2. The process as claimed in claim 1 providing two different aluminum alloys selected from 5 series and 7 series aluminum alloys of an AA standard that are formulated by The American Aluminum Association Inc. and having a single covering.

3. The process as claimed in claim 1 providing multiple different aluminum alloys selected from 5 series and 7 series aluminum alloys of an AA standard that are formulated by The American Aluminum Association Inc. and having multiple coverings.

4. The process as claimed in claim 2, wherein the core is selected from the 7 series aluminum alloys and the covering is selected from the 5 series aluminum alloys.

5. The process as claimed in claim 2, wherein the core is selected from the 5 series aluminum alloys of and the covering is selected from the 7 series aluminum alloys.

6. The process as claimed in claim 3, wherein adjacent coverings are selected from different aluminum alloys.

7. The process as claimed in claim 6, wherein the core is selected from the 7 series aluminum alloys and a covering that is mounted adjacent to the core is selected from the 5 series aluminum alloys.

8. The process as claimed in claim 6, wherein the core is selected from the 5 series aluminum alloys and a covering that is mounted adjacent to the core is selected from the 7 series aluminum alloys.

9. The process as claimed in claim 2, wherein the 5 series aluminum alloys are selected from 5051, 5052, 5056, 5086, 5086 and 5456 aluminum alloys.

10. The process as claimed in claim 2, wherein the 7 series aluminum alloys are selected from 7001, 7005, 7046, 7050, 7055 and 7075 aluminum alloys.

11. The process as claimed in claim 3, wherein the 5 series aluminum alloys are selected from 5051, 5052, 5056, 5086, 5086 and 5456 aluminum alloys.

12. The process as claimed in claim 3, wherein the 7 series aluminum alloys are selected from 7001, 7005, 7046, 7050, 7055 and 7075 aluminum alloys.

13. An extrusion product made of matrix composite aluminum alloys as manufacturing by the process in claim 1 comprising: a core and at least one covering mounted around the core wherein the core and the at least one covering are selected from different aluminum alloys.

14. The extrusion product made of matrix composite aluminum alloys as claimed in claim 13, wherein the extrusion product is a solid extrusion bar.
