用于金属箔产品的原料及其制造方法
摘要：
涉及用于金属箔产品的原料及其制造方法。公开一种产品包括：由非锭铸造工艺制成的1xxx、3xxx和8xxx系列铝合金，对于箔产品铝合金具有约5微米到约150微米的厚度。产品具有比使用平板或辊铸造工艺加工的O-回火铸造的同种合金的平均值大至少10％的O-回火拉伸强度、O-回火延伸和O-回火马伦压力。产品基本上没有由金属间颗粒的中心偏析所导致的针孔。在另一个实施例中，本发明公开由非锭铸造工艺制成的8111或8921铝合金，对于箔产品铝合金具有约5微米到约150微米的厚度。产品具有比通过使用由平板或辊铸造工艺制备的原料制成的O-回火的同种合金的平均值大至少10％的O-回火拉伸强度、O-回火延伸和O-回火马伦压力。产品基本上没有由金属间颗粒的中心偏析所导致的针孔。
摘要（英）：

The present invention relates to a feedstock for metal foil product and a method of making thereof, and discloses a product comprising a 1xxx, 3xxx and 8xxx series aluminum alloy made by a non-ingot casting process, wherein 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.
