电极火花专用钨铜电极

    CuW alloys are used where the combination of high heat resistance, high electrical and thermal 

conductivity, and low thermal expansion are needed. Some of the applications are in electric 

resistance welding, as electrical contacts, and as heatsinks. As contact material the alloy is 

resistant to erosion by electric arc. WCu  alloys are also used in electrodes for electrical discharge machining and  electrochemical machining.  

    CuW合金用于高耐热、高导电、导热性和低的热膨胀,部分应用于电阻焊接,电接触,散热器 

作为接触材料,钨铜合金耐电弧腐蚀。钨铜合金也应用于放电加工和电化学加工的电极。

    Copper–tungsten (tungsten–copperCuW, or WCualloy is a pseudo-alloy of copper 

and tungsten. As copper and tungsten are not mutually soluble, the material is composed of 

distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore 

rather a metal matrix composite instead of a true alloy.

    铜钨合金是一种钨铜伪合金。由于铜和钨不是相互溶解的,所以材料由分散在另一种金属的 

基体中的一种金属的不同颗粒构成。 因此,其微观结构是相当于金属基质复合材料而不是真正 

的合金。

   The material combines the properties of both metals, resulting in a material that  is heat

-resistant, ablation-resistant, highly thermally and electrically conductive and easy to machine. 

   该材料结合了两种金属的性质,是具有耐热,耐消融,高导热和导电性能,易于加工的材料。 

   Parts are made from the CuW alloy by pressing the tungsten particles into a desired shape, 

sintering the compacted part, then infiltrating with molten copper. Sheets, rods  and bars of the 

alloy are available as well.

   部件由CuW合金制成,通过将钨颗粒压制成所需形状,烧结压实部件,然后用熔融铜渗透。  

合金的板材,棒材和棒材也可以使用。 

   Commonly used copper tungsten alloy contains 10–50 wt.% of copper, the remaining portion 

being mostly tungsten. The typical properties of the alloy depend on its composition. The alloy 

with less wt.% of copper has higher density, higher hardness and higher resistivity. The typical 

density of CuW90 alloy, with 10% of copper, is 16.75 g/cm3 and 11.85 g/cm3 for CuW50 alloy. 

CuW90 has higher hardness and  resistivity of 260 HB kgf/mm2 and 6.5 μΩ.cm than CuW50. 

   通常使用的铜钨合金含有10-50wt的铜,其余部分主要是钨。 合金的主要性质取决于其 

组成。 铜的重量百分比小的合金具有更高的密度,更高的硬度和更高的电阻率。 铜含量为 

10%CuW90合金的密度为16.75g /   cm3CuW50合金为11.85g / cm3。 CuW90相比CuW50 

有更高的硬度260HBkg / mm2和电阻率6.5μΩ.cm
