Zinc-copper-titanium intermediate alloy for non-vacuum casting, and preparation method of zinc-copper-titanium intermediate alloy

The invention provides zinc-copper-titanium intermediate alloy for non-vacuum casting, and a preparation method of the zinc-copper-titanium intermediate alloy. The zinc-copper-titanium intermediate alloy consists of a zinc element, a copper element, a titanium element and inevitable impurities, wherein the weight percentage of the zinc element is 75-95%; the weight percentage of the inevitable impurities is smaller than 0.1%; the balance is the mixture of the copper element and the titanium element with the mass ratio of the copper element to the titanium element to be (5-25):1. The zinc-copper-titanium intermediate alloy is used during zinc alloy casting, and has the benefits that after the technology disclosed by the invention is adopted, alloy elements can be quickly molten in zinc melt, so that the production efficiency is improved; the technology is simple, safe and reliable, and is convenient to operate; the technology has higher market competitiveness, and is suitable for large-scale industrial production.
