Problems solved by technology

[0002] Beryllium bronze has a development history of more than one hundred years, and plays a pivotal role in the industrial field, especially in the manufacturing of precision instruments and meters. However, because the raw material beryllium content of beryllium bronze is scarce, accounting for only 0.0005% of the earth's crust, its price is very expensive , beryllium is very toxic in the production of gold alloying, especially in the melting process, which endangers the health of operators. In addition, the production process of beryllium bronze has strict requirements, many processes, and long streamlines. Not only that, but also consumes a lot of energy. high production cost

Embodiment 1

[0035] The titanium-copper alloy material of the present invention is made of 5.4% Ti, 93.8% Cu and 0.8% Al through casting and rolling to produce a Cu-Ti-Al three-element alloy.

[0036] The production method of titanium-copper alloy includes melting and casting, homogenization treatment, hot rolling, quenching, pickling, cold rolling, and aging. The process steps are:

[0037] Casting process:

[0038] Put 93.8% of Cu into the vacuum induction furnace to melt, put in 5.4% of Ti material immediately after the Cu material is melted, turn the furnace body to increase the liquid level for easy exhausting, the exhausting time is 10 minutes, and then put in 0.8% Ti material Three-element Al can be poured after standing still for 10 minutes, pouring temperature: 1100-1150°C; pouring speed: 10 seconds / piece; water quenching immediately after mold removal;

[0039] Homogenization process:

[0040] The supersaturated surface ingot is placed in a 10KW electric furnace for heating, th...

Embodiment 2

[0062] The titanium-copper alloy material of the present invention is made of 5.6% Ti, 93.4% Cu and 1% Al through casting and rolling to produce a Cu-Ti-Fe three-element alloy.

[0063] The production method of titanium-copper alloy includes melting and casting, homogenization treatment, hot rolling, quenching, pickling, cold rolling, and aging. The process steps are:

[0064] Casting process:

[0065] Put 93.4% of Cu into the vacuum induction furnace to melt, put in 5.6% of Ti material immediately after the Cu material is melted, turn the furnace body to increase the liquid level for easy exhausting, the exhausting time is 8 minutes, and then put in 1% Ti material Three-element Fe, stand still for 10 minutes, it can be poured, pouring temperature: 1100-1150°C; pouring speed: 8 seconds / block; water quenching immediately after mold removal;

[0066] Homogenization process:

[0067] The supersaturated surface ingot is placed in a 10KW electric furnace for long-term heating, fo...

Abstract

This invention discloses a method for producing Ti-Cu alloy material. The Ti-Cu alloy material is produced from Ti 5.8-6.1% and Cu 93.9-94.2% by smelting, casting, and rolling. Besides, a third element (one of Al, Fe, Cr and Cd) 0.5-1% can also be added to form a ternary metal. The method comprises: smelting the above components, casting, homogenizing, hot-rolling, quenching, washing with acid, cold-rolling, and aging. The obtained Ti-Cu alloy material has such advantages as high strength, high elasticity, high wear resistance, high corrosion resistance, and high weldability.

Description

technical field [0001] The invention relates to a copper alloy, in particular to a titanium-copper alloy used to replace beryllium bronze. Background technique [0002] Beryllium bronze has a development history of more than one hundred years, and plays a pivotal role in the industrial field, especially in the manufacturing of precision instruments and meters. However, because the raw material beryllium of beryllium bronze is scarce, accounting for only 0.0005% of the earth's crust, its price is very expensive , beryllium is very toxic in the production of gold alloying, especially in the melting process, which endangers the health of operators. In addition, the production process of beryllium bronze is strict, with many processes and long flow lines. Not only that, but also consumes a lot of energy. Production costs are high. Because beryllium bronze has the above disadvantages, a new copper-based elastic material needs to be developed to replace it. Contents of the inve...
