A FEEDSTOCK FOR METAL FOIL PRODUCT AND METHOD OF MAKING THEREOF |
摘要 |
The present invention discloses a product comprising a 1xxx, 3xxx and 8xxx series aluminum alloy made by a non-ingot casting process, where the aluminum alloy has a thickness of about 5 micrometers to about 150 micrometers for a foil product. The product has an O-temper tensile strength, O-temper elongation, and O-temper Mullen pressure that are at least 10 % greater compared to the average values of the same alloy in O-temper cast using a slab or roll-casting process. The product is substantially free of pinholes caused by centerline segregation of intermetallic particles. In another embodiment, the present invention discloses a 8111 or 8921 aluminum alloy made by a non-ingot casting process, where the aluminum alloy has a thickness of about 5 micrometers to about 150 micrometers for a foil product. The product has an O-temper tensile strength, O-temper elongation, and O-temper Mullen pressure that are at least 10 % greater than the average values of the same alloy in O-temper made from feedstock prepared by slab or roll casting processes. The product is substantially free of pinholes caused by centerline segregation of intermetallic particles. |
