We supply nonferrous metal casting products such as copper-based alloy sleeves, zinc-based die-casting alloy and other products.
Wear-resistant zinc-based alloy sleeves with high strength are applied in products such as sleeves, and worm gear. Its wear-resisting property can be 2-4 times higher than that of copper alloy sleeves but the price is lower than 50% of copper alloy. Wear-resistant zinc-based alloys are known as white bronze and are the most valuable metal in the 21st century.
With low-pressure technology, the high-density and complex-shaped products have no loose, internal cracks, blow holes, slag, and other casting defects made with the traditional casting process.
