Introduction
Copper-Ferro Alloy is an alloy of Copper (Cu) and Iron (Fe).
Because of much differences between the two elements, Copper and Iron, in their metal properties, eutectic points and specific gravities, making alloy of the two elements was
not possible.But with the development of Special Dissolution Technology, we succeeded in Alloying Copper + Ferro Under the effort of our RD team and special smelting technology and furnace.Cu-Fe alloy has such Copper properties as electric conductivity, thermal conductivity, malleability, spring effect and such Iron properties as wear resistance, tensile strength, hardness and magnetic force. During smelting process we can control the Cu Fe chemical weight % to meet almost all application need.
To strength the shielding effect of electromagnetic wave it needs high costs, where spring effect is required it is easily worn down and where electric conductivity is required it has little strength. These conflicting problem can now be solved with our smelted Cu-Fe alloys
Cu-Fe functions
(1) Shielding Effect of Electromagnetic Waves
(2) Spring Effect
(3) Electric Conductivity & Wear Resistance
Applications
Metal Casting
Semiconductor
Electronic Parts
Communication
Automobile
Industrial Robot
Aerospace
Railway transport.
NEXTECK supplies variety standards and customized world-class resistance alloys. All materials from strips, sheets, foils, wires as well as E-Beam Welding strips (EBW) are built for low value surface mount resistors, auto potentiometers, consumer electronics, tests, automatic controls and other fields.
NEXTECK originated in the metal smelting and processing and has a very long history. We belongs to the world's leading company in the production of thermo-electric alloys, resistance alloys, low resistance precision resistances and power resistances.
It is more effective to ensure product quality and customer service. Our measurements (standard temperature, mechanical and electronic) received long-term monitoring, which ensures the accuracy of the product again. The chemical and physical properties of our alloys are ensured through modern measuring and analysis systems. Among others, these include: optical emission spectrometer, surface electron microscope (SEM), EDX analyzer, elongation tester as well as length and hardness test devices.
