Abstract

The invention discloses a copper zinc alloy die. The copper zinc alloy die comprises, by weight, 30-40 parts of copper, 35-42 parts of zinc, 0.05-0.09 part of silicon, 0.3-0.6 part of manganese, 0.008-0.03 part of cobalt, 0.6-0.99 part of niobium, 0.336-0.544 part of magnesium, 0.25-0.44 part of chromium and 5-10 parts of iron. The copper zinc alloy die has the beneficial effects that component cooperation is scientific and reasonable, the bonding strength of components is high, the mechanical property of a copper zinc alloy is greatly improved, and the stability performance of the components is higher.

Description

technical field [0001] The invention relates to a mold, in particular to a copper-zinc alloy mold. Background technique [0002] Dies are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, die casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). [0003] The mechanical properties of zinc and zinc alloys are similar to those of copper strips, and zinc resources are abundant, and the price is lower than copper. Substituting zinc for copper has become a research hotspot in recent years. At present, there are few studies on copper-zinc composite strips at home and abroad, and the main preparation methods mainly include solid-solid composite methods such as rolling cladding, explosive cladding,...
