Dongguan Da Ling Shan Chang Sheng processing hardware store high aluminum zinc alloy typically ternary or higher alloy that has the characteristic that different melting and casting process parameters zinc alloy jewelry, manufactured material on performance there are significant differences; some elongation better suited to the manufacture of zinc alloy zipper fastener pieces, some high strength suitable for the manufacture of high strength zinc alloy case, only a small part of the anti-friction coefficient is small for the manufacture of plain bearings ; therefore high aluminum zinc alloy in a foreign country is known as the "magic alloy." Generally zinc alloy products, zinc-based alloys are high-alumina bearing zinc-based alloy, but not all high aluminum zinc alloy sliding bearing alloys.
