Abstract

The invention discloses a copper alloy and relates to the technical field of alloy materials. The copper alloy comprises the following components by weight percent: 7.5%-8.5% of aluminum, 2.5%-3.0% of iron, 2% of phosphorus, 0.1%-0.3% of rare earth, 1%-2% of nickel and the balance of copper. The copper alloy disclosed by the invention is a six-element alloy, not only has the performances of an aluminum-bronze alloy, but also integrates a nickel alloy and rare earth; the copper alloy disclosed by the invention has relatively high hardness and toughness, good mechanical properties and manufacturability and relatively high stability and can be used after processing without any thermal treatment, so that the processing time is shortened and the production cost is reduced.

Description

Copper alloy

Technical field

The present invention relates to technical field of alloy material, be specifically related to a kind of copper alloy with high rigidity and high tenacity.

Background technology

Copper alloy has the history of several thousand in China, people do arms, pot for cooking rice, the armor, tripod etc. with it in ancient times, and modern is mainly used in copper alloy the various machineries such as Aeronautics and Astronautics, military project, high ferro, has mechanical place just to have copper alloy.Xantal is a kind of important Cu alloy material, aluminum content is generally no more than 11.5%, aluminum current bronze is generally made up of aluminium, iron and copper component, after processing, need to heat-treat strengthening, can cause like this process period long higher with cost, although its strength ratio tinbronze is high, high temperature oxidation resistance is also better, and hardness and the toughness of current xantal material can't be satisfactory.

Summary of the invention

The invention provides an Albatra metal-, need the poor problem of heat treatment reinforcement, hardness and toughness to solve the processing of existing copper alloy.

The technical solution adopted for the present invention to solve the technical problems is:

One Albatra metal-, by mass percentage, comprises following component:

Aluminium: 7.5%～8.5%;

Iron: 2.5%～3.0%;

Phosphorus: 2%;

Rare earth: 0.1%～0.3%;

Nickel: 1%～2%;

Surplus is copper.

Preferably, above-mentioned copper, aluminium, iron, nickel are electrolytic metal, can ensure the purity of copper alloy, can ensure, not containing cobalt, therefore, to have radiation-resistant advantage.

Copper alloy of the present invention is a kind of hexa-atomic alloy, in possessing McGill metals performance, also increase incorporating of nickelalloy and rare earth, nickel is a kind of noble metal, its feature is to have higher intensity and plasticity, high solidity to corrosion, infusibility (1455 DEG C of fusing points) and special physicals (ferromegnetism, high electrovacuum performance etc.), rare earth alloy can play the effect that improves toughness, thereby copper alloy of the present invention has higher hardness and toughness, good mechanical property and manufacturability, higher stability, this alloy need not any thermal treatment, process and can use, shorten process period, reduce production cost.

Embodiment

Below in conjunction with specific embodiment, the present invention is described in further detail.

One Albatra metal-, by mass percentage, comprises following component:

Aluminium: 7.5%～8.5%;

Iron: 2.5%～3.0%;
