Problems solved by technology

However, the U.S. Occupational Safety and Health Administration called for reducing the use of beryllium, because beryllium has certain toxicity, and once the human body inhales its corresponding amount of dust, it will cause fatal lung diseases
In industrial production, among the existing alloy materials, for example, the yield strength of aluminum bronze is 431MPa, and the yield strength of copper-nickel-tin alloy is 724MPa, and its performance cannot reach the level of beryllium bronze, so it has not been fully accepted by people.

Abstract

The invention provides an alloy material for the aerospace field and a manufacturing method thereof. The alloy material comprises the components by weight percent as follows: 6-10% of nickel, 6-9% of tin, 3-6% of aluminum, 0.1-0.5% of manganese, 0.02-0.1% of iron and 74.4-84.88% of copper. According to the invention, the beryllium element of a beryllium-copper alloy is replaced through complete fusion of a copper-nickel alloy material and an aluminum-tin alloy, and excellent properties of the alloy material are realized under the action of a plurality of trace elements; the yield strength of the material is greater than 980 MPa; and as a result, the alloy material provided by the invention completely takes the place of beryllium bronze and achieves the goal of environmental protection and health standards.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to alloy materials used in the field of aerospace to replace beryllium copper and a manufacturing method thereof. Background technique [0002] Beryllium bronze is made of copper-beryllium alloy. It has superior performance, and its yield strength can be higher than 965MPa. Therefore, it is widely used in high-end product parts such as bushings in the aerospace field. However, the U.S. Occupational Safety and Health Administration called for reducing the use of beryllium, because beryllium has certain toxicity, and once the human body inhales its corresponding amount of dust, it will cause fatal lung diseases. In industrial production, among the existing alloy materials, for example, the yield strength of aluminum bronze is 431MPa, and the yield strength of copper-nickel-tin alloy is 724MPa, and its performance cannot reach the level of beryllium bronze, so it has not been fully accep...
