Main elements of the production of aluminum-magnesium alloy containing aluminum is up, by adding a small amount of magnesium and other metal materials to enhance its hardness. Because aluminum metal itself is a reason, so the thermal conductivity of aluminum is relatively prominent. Therefore, only aluminum-magnesium alloy with a low density, good heat dissipation, compression and strong variety of characteristics, aluminum hardness of conventional plastics machinery several times, much lighter in weight than the former.
aluminum-magnesium alloy plate disadvantages:
the magnesium die tryout require higher costs and longer time trial, and steel parts or plastic parts is much simpler.
the magnesium die-casting and aluminum die compared to its high burning rate is 50K, which is 4% to 2%.
and aluminum die casting or low pressure ratio, magnesium die require higher tooling costs. Because the casting mold large and complex, but also to withstand high clamping force.
and aluminum die casting compared to magnesium die-casting production has a high residual scrap rate.
investment in production equipment is high magnesium die-casting. And aluminum gravity / low / Glass molds process than magnesium die casting machine is expensive, of course, its productivity is 4 times the former.
