Problems solved by technology

Although the currently used ZL205A alloy has high strength, it has poor formability, large thermal cracking tendency, and serious Cu element segregation during the liquid die forging process, which can no longer meet the requirements of liquid die forging to produce hubs. Therefore, it is urgent to develop a A new type of high-strength and high-toughness aluminum alloy for liquid die forging solves the problem of wheel hub liquid die forging

Abstract

The invention aims at providing novel high-strength high-toughness Al-Cu alloy. The novel high-strength high-toughness Al-Cu alloy is good in forming property, small in hot cracking tendency, good in liquid die forging forming property and feeding property and small in amount of loose tissue. The novel high-strength high-toughness Al-Cu alloy is composed of, by weight, 0.05%-0.2% of Zr, 0.005%-0.06% of B, 4.6%-7.0% of Cu, 0.15%-0.35% of Ti, 0.3%-0.5% of Mn, 0.05%-0.3% of V, 0.15%-0.25% of Cd, 0.12%-0.18% of Fe, 0.03%-0.09% of Si and the balance Al.

Description

technical field [0001] The invention relates to a novel Al-Cu alloy with high strength and high toughness. Background technique [0002] In view of the high performance and lightweight requirements of the wheel hub, higher requirements are put forward for the forming raw materials. Although the currently used ZL205A alloy has high strength, it has poor formability, large thermal cracking tendency, and serious Cu element segregation during the liquid die forging process, which can no longer meet the requirements of liquid die forging to produce hubs. Therefore, it is urgent to develop a A new type of high-strength and high-toughness aluminum alloy for liquid die forging solves the problem of wheel hub liquid die forging. Contents of the invention [0003] The object of the present invention is to provide a new high-strength and high-toughness Al-Cu alloy with good formability, low thermal cracking tendency, good liquid die forging formability and feeding performance, and l...
