Copper Tungsten Bar Stock

Copper tungsten bar stock is a composite with remarkable properties of tungsten and copper. This metal combination is astonishing due to its electric arc and extreme temperature resistance. Besides this, it has exceptional strength and density.

We use powder metallurgy as the method of production for our parts. It starts with the blending of copper and tungsten powder particles, followed by pressing and heating to create a solid part. One commercially available form of the material is called 70/30 copper-tungsten, meaning that 70% of the specimen is copper and the remaining portion is tungsten.

All copper-tungsten alloys are unique in their external appearance as well as their density. Take for instance, CuW90 (90% tungsten and 10% copper) which boast of a staggering density of 16.75 grams per cubic centimeter. Another grade like CuW50 (50% tungsten and 50% copper) is significantly lower at 11.85 grams per cubic centimeter. From these examples, it can be reinforced that the alloy possess astonishing dense and hard enabling his wide applications.

Due to low weight being crucial for some applications, these alloys are unique and fulfill these requirements, such as for some components of machines used in electrical discharge machining. The machining method utilizes electricity to perform metal cutting. It is also employed for manufacturing electrical contacts. These are components that serve as current gates into devices and vice versa. The contacts are also suitable for resistance welding. This welding method joins metal parts with electric currents by heat produced.

So, copper tungsten is a very useful material for many different jobs because it combines the best qualities of two metals and can handle tough conditions.

1. Excellent thermal conductivity

2. Durable use

3. Good arc resistance·Good machinability

4. Excellent electrical conductivity

5. Low thermal expansion rate

The copper tungsten rods can be used for electronic packaging which helps to encase semiconductor devices. In simpler terms, semiconductor devices are small processors that are present in many electronic devices. The thermal expansion coefficient of the rods is compatible with the ceramics and semiconductors. This is useful because the copper tungsten rod along with the semiconductor or ceramic piece contains devices during the heating or cooling cycles without conflicting rates of expansion and contraction. With minimal movement, damage in the form of cracks or other means becomes less likely, ensuring that the electronic device operates optimally for a longer duration.

The most distinguishing feature is the exceptional machinability of copper tungsten rods. These rods can be transformed into various mechanical components. They can even be fabricated into molds which allows for the rearrangement of other materials into specific shapes. Moreover, the strength and hardness make copper tungsten rods ideal, as the extreme temperatures and pressures during the molding process will not be surpassed. These rods can be shaped into implements which range from hand-held tools to components of intricate machines. In all instances, the reliability and dependability of tools created from copper tungsten rods is exceptional.
