Problems solved by technology

The No. 3 zinc ingot produced according to this method has insufficient toughness, which leads to the failure of downstream die-casting products. For this reason, we have developed a new high-performance die-casting zinc alloy material, which improves the toughness of the zinc alloy material while maintaining the tensile strength. No precious metal Cu is used. , reducing production costs

Abstract

The invention relates to a novel high-performance die-casting zinc alloy material, and particularly relates to a novel zinc alloy material suitable for die casting. The zinc alloy novel material comprises the following components in mass percentage by adjusting the percentage content of Al and being matched with a melt treatment process: 3.3-4.3% of Al, 0.02-0.06% of Mg, no more than 0.1% of Fe, no more than 0.005% of Pb, no more than 0.003% of Sn, no more than 0.004% of Cd and the balance Zn. The novel high-performance die-casting zinc alloy material has the higher tensile performance compared with an existing third zinc alloy, and meanwhile, the higher die-casting performance and the lower cost are achieved.

Description

technical field [0001] The invention relates to a new die-casting zinc alloy material, in particular to a new die-casting zinc alloy material with high strength and toughness. Background technique [0002] With the continuous development of the global economy, although copper and copper alloys are used more and more widely, the price of copper alloys is also getting higher and higher. In order to replace copper and copper alloy materials to meet the development of modern industry and global economy The country puts forward the development strategy of "replacing copper with zinc". In my country, zinc alloys are used for die casting and account for more than 20%. Among them, YZZnAl4A (No. 3 die-casting zinc alloy), ZA8 alloy, and ZA12 are commonly used die-casting zinc alloys. Because No. 3 zinc alloy has good fluidity near the eutectic point, it is recognized as the development direction of die-casting zinc alloys. At present, more than 70 % ZnAl4 is used in zinc-aluminum a...
