Abstract
Official abstract text for this publication.
An aluminum alloy comprising greater than 2.00 and less than 4.00 wt. % cerium, 0.25-3.00 wt. % silicon, 0.25-0.75 wt. % magnesium, 0-0.75 wt. % iron, 0-0.05 wt. % other alloying elements, and the balance of aluminum, based on the total weight of the aluminum alloy aluminum alloy.
First claim
Opening claim text (preview).
What is claimed is: 1. An aluminum alloy powder comprising: 9.0 wt. % cerium, 2.00-3.00 wt. % silicon, 0.25-0.75 wt. % magnesium, 0-0.75 wt. % iron, 0-0.05 wt. % other alloying elements, and the balance of aluminum, based on the total weight of the aluminum alloy powder. 2. The aluminum alloy powder of claim 1 , comprising 2.00 wt. % silicon, based on the total weight of the aluminum alloy powder. 3. The aluminum alloy powder of claim 1 , comprising 3.00 wt. % silicon, based on the total weight of the aluminum alloy powder. 4. The aluminum alloy powder of claim 1 , comprising 0.75 wt % iron, based on the total weight of the aluminum alloy powder. 5. The aluminum alloy powder of claim 1 , comprising greater than zero wt % iron in an amount up to 0.30 wt. % iron, based on the total weight of the aluminum alloy powder. 6. The aluminum alloy powder of claim 1 , comprising 0.25-0.75 wt. % iron, based on the total weight of the aluminum alloy powder.
