What is A-1 Alloy used for the holders of the Link Ball?
A-1 Alloy, based on Al, Zn, and Si, has the following features. -The highest strength among any die casting aluminum alloy -Proof stress approximately twice that of ordinary die casting aluminum alloy (e.g., ADC12) -Hardness equivalent to that of high strength zinc alloy. -Specific gravity of half or less than half that of high strength zinc alloy. A substantial weight reduction is therefore possible. Excellent in high corrosion resistance.
