Abstract (en)
[origin: WO2008144935A1] The present invention relates to modified alloy compositions for reduced hot tear susceptibility, where the aluminum alloy comprising from 0.01 to 0.025 % by weight of Sr; and TiB2, measured by its boron content, from 0.001 to 0.005% by weight of B. The invention also relates to method of preventing or eliminating hot tears in an aluminum alloy comprising the step of combining with aluminum from 0.01to 0.025 % by weight of Sr; and TiB2, measured by its boron content, from 0.001 to 0.005% by weight of B.
