Abstract

The invention discloses a cracking-resistant copper alloy glass mold inlaid with boron nickel alloy. The glass mold comprises a copper alloy layer and a boron nickel alloy layer inlaid on the copper alloy layer, wherein the copper alloy layer comprises the following components in percentage by weight: 8.5-10.5% of Al (aluminum), 14-16% of Ni (nickel), 7.5-9.5% of Zn (zinc), 0.8-1.2% of Si (silicon), 0.8-1.2% of Fe (ferrum), 0.05-0.15% of Mn (manganese), and the balance of Cu (copper); the boron nickel alloy layer comprises the following components in percentage by weight: 2.2-2.5% of B (boron), 0.1-0.2% of C (carbon), 0.5-1.0% of Cr (chromium), 0.2-0.5% of Fe (ferrum), smaller than 0.003% of S (sulfur), 3.0-3.5% of Si (silicon), smaller than 0.5% of Al (aluminum), and the balance of Ni (nickel). After the copper alloy glass mold is used 1500,000 times, the phenomenon that the boron nickel alloy layer and the copper alloy layer are cracked and stripped does is avoided.

Description

technical field [0001] The invention relates to a copper alloy mold, in particular to a crack-resistant copper alloy glass mold inlaid with boron-nickel alloy. Background technique [0002] The overall performance of the copper alloy glass mold is excellent, and the mouth size of the glass bottle produced by the copper alloy mouth mold can be effectively guaranteed. However, with the development of technology and the increasingly fierce competition, bottle manufacturers hope that glass molds can have a longer service life to reduce production costs and enhance corporate competitiveness. [0003] In the prior art, the inner cavity of the copper alloy die is further processed by spraying nickel alloy, but due to the limitation of the production process, the spray welding layer is prone to spray welding pores and easy to fall off, resulting in low production efficiency of the mold itself and The quality is not constant. [0004] After conducting research, the applicant tried ...
