Die casting is one of the most popular parts at the moment, and its function and role cannot be underestimated. lead die casting should be used for chemical corrosion protection, radiation protection, and the production of battery panels and cable sleeves.
If the lead alloy contains impurities such as bismuth, magnesium, zinc, etc., which are not solid-soluble in lead or form the second phase, the corrosion resistance will be reduced; adding tellurium and selenium can eliminate the harmful effects of impurity bismuth on corrosion resistance. Adding antimony and tellurium to the lead alloy containing bismuth can refine the grain structure, increase the strength, inhibit the harmful effects of bismuth, and improve the corrosion resistance. Lead die-casting alloy has a low melting point (below 327 ℃), good fluidity, small solidification shrinkage, less melting loss, and small composition change during remelting. It can cast devices with complex shapes and clear outlines. It is widely used in casting type and making models Wait.
