Customized Tungsten Copper Alloy Part
1. What's Customized Tungsten Copper Alloy Part?
Customized tungsten copper alloy part is a non-standard component machined to meet equipment design, assembly dimensions, and operating conditions. Its geometry may include steps, grooves, through-holes, contoured surfaces, and combined structures. CTIA's customized tungsten copper alloy part is composed of tungsten (W) and copper (Cu), fulfilling electrical and thermal conductivity requirements while balancing arc erosion resistance and low thermal expansion performance, suiting applications such as electrical switches, electronic packaging, welding equipment, and precision electrical machining.

2. Features of CTIA's Customized Tungsten Copper Alloy Part
(1) Good Electrical and Thermal Conductivity: Copper phase assists current transmission and heat dissipation, suiting electrical contacts, welding electrodes, and electronic heat dissipation components requiring electrical and thermal performance.
(2) High Temperature and Arc Erosion Resistance: High melting point of tungsten helps component withstand local high temperatures under arc action, reducing material burn and suiting components such as switch contacts and discharge machining electrodes.
(3) Adjustable Thermal Expansion Coefficient: Tungsten-to-copper ratio affects thermal expansion characteristics of material, allowing appropriate composition selection based on requirements of chips, ceramic substrates, and other matching materials to reduce dimensional differences caused by temperature variations.
(4) Flexible Material Composition: Tungsten-to-copper ratio can be selected according to operating temperature, electrical and thermal conductivity demands, and thermal expansion requirements of component, balancing performance demands under diverse operating conditions.
(5) Customizable Irregular Structures: Steps, grooves, hole positions, bevels, curved surfaces, and irregular contours can be machined according to customer requirements, adapting to installation space and structural design of various equipment.
(6) Controllable Dimensional Accuracy: Critical dimensions, hole positions, mating surfaces, and surface roughness can be controlled according to component drawings and assembly requirements, fulfilling precision machining demands for non-standard components.

3. Applications of CTIA's Customized Tungsten Copper Alloy Part
