Embodiment Construction

[0020] The present invention will be described in further detail below through specific examples.

[0021] The present invention is a beryllium-copper alloy, which contains elements Be and Co in copper, takes advantage of the interaction of alloy elements, and prepares high-strength and high-thermal-conductivity conforming amorphous and nanocrystalline ribbon production equipment through the following preparation method Beryllium copper alloy material with copper sleeve.

[0022] A preparation method of a beryllium-copper alloy copper sleeve is as follows:

[0023] (1) Smelting: prepare raw materials and accurately weigh them, and smelt them at a temperature of 1250-1350°C;

[0024] (2) Casting: pour the smelted beryllium-copper alloy into ingots or slabs, and control the pouring temperature at 1000-1150°C;

[0025] (3) Hot forging: Hot forging the billet at a temperature range of 600-910°C, and the hot forging reduction rate is ≥ 20%;

[0026] (4) Heat treatment: The heat ...

Abstract

The invention discloses a beryllium copper alloy, a copper bush for amorphous and / or nano crystal strip production equipment and a preparation method. The copper contains the following elements in percentage by mass: 0.25 to 2.1 percent of Be, and 0.1 to 2.0 percent of Co. By adding the elements such as Co and the like into the beryllium copper alloy, the advantage of interaction of the alloy elements is exerted; and the smelted alloy is cast into a cast ingot or a cast blank, and the cast blank is subjected to the processes of hot forging, heat preservation, ageing treatment and the like to prepare the beryllium copper alloy with high strength and high thermal conductivity and in accordance with the copper bush for the amorphous or nano crystal strip production equipment. When the beryllium copper bush is applied in the strip production link, the appearance quality and the actual performance of amorphous or nano crystal strips can be effectively promoted.

Description

technical field [0001] The invention relates to a copper sleeve for production equipment of beryllium copper alloy and amorphous and / or nanocrystalline strip material and a preparation method. Background technique [0002] Beryllium copper alloy is an alloy with good mechanical, physical and chemical comprehensive properties. It is a wrought and castable alloy, which is a copper-based alloy strengthened by aging precipitation. After quenching and aging treatment, it has high strength, hardness and elasticity. It has a series of advantages such as corrosion resistance, wear resistance, fatigue resistance, low temperature resistance, non-magnetism, good electrical and thermal conductivity, and no sparks when impacted. It is known as the "king of colored elastic materials". In recent years, the scope of application of beryllium copper alloy has gradually expanded, and it is widely used in various fields such as electronic appliances, communication instruments, aerospace, petroc...
