  • Patent number: 11319501
    Abstract: A pre-lubricated stock sheet and a method and system for making the same are described. The pre-lubricated stock is generally in a coil wound form. The stock sheet can have opposing first and second sheet surfaces joined together by opposing side edges and opposing ends. Typically, the first and second sheet surfaces are substantially smooth and planar, wherein the sheet has 3 mg/foot2/side to about 200 mg/foot2/side of a solid lubricant having a melting temperature from about 80 to 212 degrees Fahrenheit. Moreover, the opposing side edges usually are substantially free of the solid lubricant. In some configurations, the stock sheet is an aluminum stock sheet, more particularly an aluminum can stock sheet. Furthermore, the lubricant can be in some configurations a food grade lubricant, that is qualifies a low volatile organic compound under one or more of municipal, state and federal governing authorities.

  • Patent number: 5110545
    Abstract: An aluminum alloy that can be fabricated into aluminum sheet having novel properties is provided. The strip stock is suitable for the fabrication of both container ends and container bodies in thinner gauges than are typically presently employed, has low earing characteristics and may be derived from recycled aluminum scrap. The alloy preferably has a magnesium concentration of from about 2 to about 2.8 weight percent and a manganese concentration of from about 0.9 to about 1.6 weight percent. The process preferably includes continuous chill block casting the alloy melt into a strip, hot rolling the strip to a first thickness, annealing the hot rolled strip and then cold rolling the annealed strip to a final thickness. Cold rolling preferably includes two stages with an intermediate anneal step between the two stages. The process increases tensile and yield strength while decreasing earing percentage, even in very thin gauges, such as 0.010 inches.

  • Patent number: 4976790
    Abstract: This invention relates to a process for producing aluminum-containing strip stock which is suitable for drawing and ironing and has reduced earing. A continuously-cast, aluminum-containing strip is introduced into a hot-mill operation to provide a thickness reduction of at least 70 percent with the exit temperature of the strip being minimized. The strip is allowed to crystallize to form grain having an annealed texture. This strip is then subjected to cold rolling to reduce the thickness at least 30 percent. The cold-rolled strip is annealed at an intermediate annealing temperature. The annealed strip is then subjected to further cold rolling sufficient to optimize the balance between the 45.degree. earing and yield strength.
