75WCu Tungsten Copper Components for CNC Machining Equipment 

Product Introduction

Zhuzhou Jiuding Metal Technology Corp Ltd specializes in high-precision manufacturing and customization of 75WCu Tungsten Copper Components for CNC machining equipment, precision machine tools and industrial mechanical systems. 75WCu alloy consists of 75% high-purity tungsten and 25% copper, offering a perfect combination of tungsten’s high rigidity, wear resistance and low expansion, and copper’s superior thermal conductivity and excellent machinability. As a core functional and structural material for modern CNC equipment, 75WCu components maintain stable physical performance under long-term high-temperature, high-speed and heavy-load operating conditions, effectively improving equipment precision, heat dissipation efficiency and overall service life.

Traditional steel, brass and pure copper machine parts commonly suffer from thermal deformation, poor heat dissipation, low rigidity and severe wear during continuous CNC machining, resulting in accuracy attenuation, unstable operation and frequent part replacement. Our premium 75WCu tungsten copper components completely solve these industry pain points. With optimized alloy proportion and dense microstructure, the material delivers outstanding dimensional stability and thermal management performance, making it the ideal upgrade accessory for high-precision CNC machining equipment.

Core Material Advantages of 75WCu Tungsten Copper

Manufactured via advanced powder metallurgy and copper infiltration processes, our 75WCu tungsten copper components feature uniform microstructure, zero porosity, stable chemical composition and excellent batch consistency. The material integrates multiple superior mechanical and thermal properties uniquely suitable for CNC machining equipment parts:

• Superior Thermal Conductivity: 75WCu alloy provides efficient heat dissipation, rapidly conducting away high temperature generated during long-term CNC operation and cutting processes. It effectively avoids local heat accumulation and thermal deformation of mechanical parts, ensuring consistent equipment precision.

• Ultra-Low Thermal Expansion: With a low linear expansion coefficient, the material maintains excellent dimensional stability under drastic temperature changes, minimizing thermal displacement and precision loss of CNC structural components.

• High Rigidity & Wear Resistance: High tungsten content endows 75WCu with high hardness and structural rigidity, greatly resisting mechanical wear and micro-deformation during high-frequency operation, extending component service life significantly.

• Excellent Structural Stability: Dense and uniform alloy structure delivers strong fatigue resistance and oxidation resistance, adapting to long-duration continuous industrial operation without structural failure or performance attenuation.
