Abstract
In an Al—Si alloy for casting, the Ti content is no more than 0.05 mass %. The Al—Si alloy for casting preferably has an Si content of 5.0-12.0 mass %, and preferably has an Mn content of 0.4-1.5 mass %, an Mg content of 0.05-0.6 mass %, a Cr content of 0.1-0.5 mass %, and an Fe content greater than 0 and no greater than 0.6 mass %, with the remainder comprising Al and inevitable impurities.
Claims8
An Al—Si alloy for casting, characterized in that a Ti content is 0.05% by mass or less.
A method for producing an Al—Si alloy casting, comprising:
- a Ti removal step of adding B to a molten Al—Si alloy to convert Ti in the molten alloy to TiB2, and then removing the TiB2;
- and
- a casting step of casting the molten alloy that has been subjected to the Ti removal step to obtain an Al—Si alloy casting,
- wherein the Ti content of the Al—Si alloy casting is set to 0.05% by mass or less by the Ti removal step, and
- a limit bending angle of the Al—Si alloy casting in the VDA bending test specified in VDA238-100 is set to 330 or more.
