Problems solved by technology

As we all know, the alloying elements chromium Cr, nickel Ni, molybdenum Mo, vanadium V, etc., or tungsten W, titanium Ti, and cobalt Co are expensive. The steel grades produced with these alloying elements are extremely expensive, and the manufactured parts must be sold at high prices. , less market sales
At the same time, the tools made of these expensive steel materials have a long service life and a waste of resources.

Embodiment 1

[0014] A copper alloy material for auto parts, using copper as a raw material, the weight of copper is 70 parts, and also includes the following components by weight: 0.12 parts of platinum; 0.8 parts of aluminum; 1 part of technetium; 0.22 parts of chromium; 0.12 parts of tungsten.

[0015] The beneficial effect of the present invention is: using copper as the main raw material, by adjusting and controlling the composition ratio and adding sequence of the elements in the alloy steel, the strengthening effect of the aluminum element is improved, so that the copper has good strength and reduces the production process. The resulting crack phenomenon improves the quality of copper.

Embodiment 2

[0017] A copper alloy material for auto parts, using copper as raw material, the weight of copper is 75 parts, and also includes the following components by weight: 0.2 parts of platinum; 1.2 parts of aluminum; 2 parts of technetium; 0.28 parts of chromium; 0.25 parts of tungsten.

[0018] The beneficial effect of the present invention is: using copper as the main raw material, by adjusting and controlling the composition ratio and adding sequence of the elements in the alloy steel, the strengthening effect of the aluminum element is improved, so that the copper has good strength and reduces the production process. The resulting crack phenomenon improves the quality of copper.

Embodiment 3

[0020] A copper alloy material for auto parts, using copper as a raw material, the copper has 80 parts by weight, and also includes the following components by weight: 0.25 parts of platinum; 1.5 parts of aluminum; 3 parts of technetium; 0.34 parts of chromium; 0.35 parts of tungsten.

[0021] The beneficial effect of the present invention is: using copper as the main raw material, by adjusting and controlling the composition ratio and adding sequence of the elements in the alloy steel, the strengthening effect of the aluminum element is improved, so that the copper has good strength and reduces the production process. The resulting crack phenomenon improves the quality of copper.

Abstract

The invention discloses a copper alloy material for automobile parts. Copper is used as a raw material, and the copper alloy material is prepared from the following components in parts by weight: 0.12 to 0.25 part of platinum, 0.8 to 1.5 part of aluminum, 1 to 3 parts of technetium, 0.22 to 0.34 part of chromium and 0.12 to 0.35 part of tungsten. The copper alloy material has the beneficial effects that the copper is used as the main raw material, and the composition ratio and the adding order of all elements in alloy steel are adjusted and controlled, so that the strengthening effect of an aluminum element is increased, the copper has good strength, the cracking phenomenon generated during production is reduced, and the quality of the copper is increased.

Description

technical field [0001] The invention relates to a metal material, in particular to a copper alloy material for auto parts. Background technique [0002] Components are widely used in the processing of most mechanical products, the construction of engineering structures, the maintenance of all products, and in daily life. It should have a high-hardened surface and a low-hardness tough core. It also has high-speed cutting and processing performance, and has a certain processing red hardness. Because the steel type should have these special properties, the steel for conventional parts is mainly to add a large amount of alloying elements chromium Cr, nickel Ni, molybdenum Mo, vanadium V, etc. to medium carbon steel, and even add tungsten W, titanium Ti and cobalt Precious and rare heavy metals such as Co, through controlled smelting and alloying, rolling (forging) temperature-controlled cooling, and processing heat treatment, form a dispersed solid-solution structure and precip...
