Sand casting allows us to use more
resilient aluminum alloys that cannot be used in die casting. This
increases strength and the overall amount of aluminum in the final
product. We use Almag 535 alloy which is a high purity alloy of aluminum
and magnesium possessing the highest and most stable combination of
strength, shock resistance and ductility of any as cast non-heat treated
aluminum alloy.
The Ski Man style vise is die cast and most likely uses A380 aluminum
alloy. That type of alloy is required due to the die-cast method and
produces a vise that is much more susceptible to breakage under
repetitive stress. We are sure you have seen vise of this style broken
as shown. |
