zinc die cast
alloys that combine both strength and stability of properties on aging to give optimum service performance. These
alloys are No. 3, No 5, and No. 7. Both No. 3 and No. 7 are excellent
alloys, either of which can be used for most applications.
Alloy No. 3 is currently the most popular
alloy, but No. 7 will perform equally well and under certain conditions is superior to No. 3.
Zinc cast
alloy No. 7 has lower magnesium content, with additional...
