Copper Tungsten Weld Wheel

Copper Tungsten Weld Wheel commanly made of material of Class 11 Copper Tungsten contains 25% copper and 75% tungsten. Common uses include projection welding electrodes, flash and butt welding electrodes, light upsetting and seam welding bushings, and spot welding low conductivity steels. It is also widely used in chip carriers, substrates, flanges, and frames for power semiconductor devices.

Copper Tungsten Weld Wheels adopts the process of isostatic pressing - high temperature sintered tungsten skeleton - infiltration of copper, which is suitable for EDM and welding of steel and wire. Ordinary electrodes have large loss and slow speed.

Copper Tungsten Weld Wheels has high electro-corrosion speed, low loss rate, precise electrode shape and excellent processing performance, which can improve the accuracy and quality of the workpiece to be processed.

1. High hardness and wear resistance: The copper tungsten welding wheel combines the conductivity of copper with the immense hardness, HRC ≥ 60, of tungsten. The surface hardness is higher than that of copper alloys, servinh for superlative wear conditions.

2. High temperature resistance and ablation resistance: The tungsten matrix melting point (3410°C) and the sustaining effects of copper sweat cooling allows it to withstand exceedingly high temperatures of above 1500°C, while also having exceptional arc ablation resistance.

3. Low thermal expansion coefficient: Their CTE (6.5×10⁻⁶/K) is close to semiconductor materials which alongside having low thermal stress during welding. These features drastically lower the chances of crack formation.

1. Used for spot and roller seam welding, tawny copper and tungsten welding wheels are used in the resistance welding of copper and aluminum, since the conductive metals are highly conductive. It is noteworthy that the welding joint strength is increased by thirty percent.

2. As an Automated Production Line tool, the tawny copper tungsten welding wheel doubles as a robot, industrial robot arm wielding tools, as it is 5x more durable than traditional materials and copper tungsten welds, which extends the copper-tungsten weldon's lifespan. This significantly reduces downtime, maintenance time, and machining error rates.

3. To comply with aerospace standards of metallurgy, tawny copper tungsten welding wheels perform welding on titanium alloys and other high temperature alloys, enabling the welds to withstand high temperatures and ensuring the quality standards of aviation pretested them.
