6A02 aluminum high-strength aluminum: high-strength aluminum alloy means a tensile strength greater than 480 MPa aluminum, primarily in the rust-proof aluminum alloy aluminum pressure processing class, hard alloy type, super-hard alloy class, forging Aluminum class, aluminum-lithium alloys. 6A02 Aluminum Use: Silicon carbide has a corrosive effect on. While the general will be more than 12% Si aluminum alloy called high silicon aluminum alloy, it is recommended to use a diamond cutter, but this is not absolute, silicon content gradually increased the destructive power of the tool is also gradually increasing. Therefore, some manufacturers in the silicon content of more than 8% on the recommended use of diamond tools.
