Tungsten Copper Jewelry Uses

One client wants to put tungsten copper into jewelry function; this is first we have heard. To be jewelry, there is no other chemical composition and physical properties requirement for tungsten copper alloy, except the color. So we advice 70%W30%Cu is availed. However, he has not come back to us until now.

Tungsten Copper Manufature

Tungsten and copper is mutual metal which owns high electric and thermal conductivity of copper and arc resistance of tungsten.

Today I would like to introduce the manufacture tungsten copper: The manufacturing process is as follows: press the tungsten or tungsten carbide, sinter the copper pressed compact at a high temperature, and infiltrate it with copper. All this is done under very closely controlled conditions. The result is a relatively hard material with superior arc and wear resistance, high physical Properties: at elevated temperatures, and good electrical and thermal conductivity.

First order for tungsten copper

Today, I feel very happy that there is a first order in my sell life. Though, it is a small order, it is really very hard for me. To be a good seller, not only we need to know lots of professional knowledge, but also English and how to built friendly cooperation with clients.

Tungsten Copper CTE

Tungsten Copper CTE
As a newer for tungsten copper seller, the manufacturing and machine is difficulty for my understanding. Today there is a client want to know whether tungsten copper for 90W10Cu coefficient of thermal expansion is changed by the temperature.
I need to ask lots of technicians to answer the question, and few know the answer. According to their reply, CTE for tungsten copper alloy owns low thermal expansion and changed little under different temperature.
Meanwhile I need to know more about tungsten copper alloy knowledge to answer different question.

Tungsten Copper Properties

To understand tungsten copper which I know nothing about is a little difficulty for me, however, I believe that there is a will, there is a way. Today, I have known lots of copper tungsten alloy properties:
Tungsten copper properties are dependent on the mixture of the copper and tungsten alloy. Typically, higher levels of copper are used in jobs in which thermal and electrical conductivity is more critical and higher levels of tungsten are used when strength and hardness are needed.
1. Hardness
Hardness is defined by the Merriam-Webster website as the resistance of metal to indentation or scratching under a load. Copper is a soft metal and tungsten is considered very hard. The hardness of the copper tungsten alloy will depend on the mixture required for the application. When a harder material is required, the alloy contains a larger volume of tungsten and less copper. Softer alloys of copper tungsten will contain a higher percentage of copper.
2. Thermal Expansion
Thermal expansion is the change in size, shape or volume of a metal when exposed to heat. Copper tungsten alloys are prized to due to low thermal expansion rates. This allows the metal alloy to maintain its shape when exposed to high temperatures. Tungsten has the lowest thermal expansion rate of all the metals, according to the Engineering Toolbox. The thermal expansion rating of an alloy of copper and tungsten depends on the amount of copper present in the alloy. The more copper present, the higher the thermal expansion.
3. Electrical and Thermal Conductivity
Electrical and thermal conductivity are related because the electrons within the metal carry both the electrical charge and the thermal energy in metals, according to Fisk Alloy. Copper is one of the highest-rated metals in both electrical and thermal conductivity. In copper tungsten alloys, the higher the level of copper, the higher the electrical and thermal conductivity. These alloys are used in electrical and electronic components.
4. Wear Resistance
Copper tungsten alloys are arc- and wear-resistant, important aspects for heat sinks in electronic devices or serving as electrodes in resistance welding. The more tungsten content, the more wear-resistant the alloy.

What is tungsten copper?

Chinatungsten Online specialize in manufacturing and offering tungsten and tungsten related products for more than 20 years, however, I am new here. The first point for me is to know what copper tungsten is:

Tungsten Copper Alloy (Copper Tungsten, CuW, or WCu) is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite than a true alloy. The alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine. Parts are made from the tungsten copper alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, and then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.

My first tungsten copper dairy

Hello, everyone, this is my first day to be a seller and tungsten copper alloy is my main products. I am nervous about WCu; I know nothing about tungsten copper alloy, what is tungsten copper, what is the function of tungsten copper, etc. What I need is to learn more about tungsten copper knowledge, I am sure I can do the job well.

Meanwhile, I would like to upload a picture of tungsten copper which I took first time.
