Products Description
Tungsten copper block is an alloy formed by pressing tungsten powder and tungsten carbide powder through an isostatic pressing process, sintering at high temperature, and then filtering and infiltrating with copper. With the 6~50% copper(by weight), the W-Cu alloy has integrated both advantages of tungsten and copper. Characterized by good high temperature resistance, arc ablation resistance, thermal and electrical conductivity , high strength, machining-ease, and outstanding sweat cooling ability and specific gravity ,it is widely applied in machinery, electric power, electronics, metallurgy, aerospace and other industries.
Tungsten copper blocks have a small thermal elongation coefficient, significant electrical and thermal conductivity, high level of high temperature resistance, strong arc ablation resistance, good plasticity and workability, the highest anti-corrosion performance, sturdy structure and easy to install and other advantages,which is the best integrated circuit material and electrical contact material.
Features Of Tungsten Copper Block
1. Tungsten copper characteristics and its application: As one of the hardest metals, tungsten has the highest melting point at 3410℃. It copper has a melting point of 1083℃. Tungsten copper EDM electrodes withstand high temperatures and even severe arcs. Therefore, the EDM electrode screws have a longer service life.
2. Copper display good thermal conductivity: Copper has excellent thermal conductivity. Tungsten copper EDM electrode screws have this characteristic, which can quickly conduct current and heat, reducing electrical energy losses timley and the stabilty of equipment.
3. High strength and high hardness: These two properties of the alloy stems from copper components. Thus they Tungsten copper EDM electrode screws are underpinned undergo strong clamping without undergoing deformation or severe damage. Hence, it can withstand stress and friction.
4. Good machining performance: Tungsten copper EDM can be processed by several cutting forms such as grinding which allows tailoring into optimal sized parts. It enables greater complexity but remain less voluminous.
Applications Of Tungsten Copper Block
As an example of an application of tungsten copper blocks, it can serve as an electronic packaging materials for hot mounting boards, chip carriers, flanges, and frames of high power electronic devices. This ensures that the electronic devices function stably in diiferent environments. In terms of aerospace, it is possible to manufacture rocket engine nozzles, missile shells, and even the space shuttle's structural components which are claimed to meet the standards for high temperature, high strength and high reliability materials. It can also be used for components of control rod drive mechanisms and shielding materials for reactors designed to withstand high temperatures, high pressure and strong radiation in nuclear reactors.
