Wolfram 90% Tungsten 10% Copper Arcing Contact Tip W90Cu10 CE Certificate

CE Certificate Wolfram Copper Arcing contact tip W90Cu10

An electrical connector is a conductive device for joining electrical circuits together. The connection may be temporary, as for portable equipment, or may require a tool for assembly and removal, or may be a permanent electrical joint between two wires or devices. There are hundreds of types of electrical connectors. In computing, an electrical connector can also be known as a physical interface (compare Physical Layer in OSI model of networking). Connectors may join two lengths of flexible wire or cable, or may connect a wire or cable to an electrical terminal. Although cable glands are often called "connectors", a technical distinction can be made in the terminology, which differentiates them from quick-disconnect, conducting electrical connectors. The distinction is often not made. Higher voltage applications bring a diverse set of challenges in design and wear of electrical contacts. Some of these high voltage contacts are operated in oil, others in air, others in a vacuum and still others in varying gases to deal with the unique requirements of high voltage applications. Some of the problems encountered will be high wear, arcing and sticking (or welding).

Advantages

Higer thermal conductivity

Low thermal expansion

High arc resistance combined with good electrical conductivity

Applications

1.Resistance Welding
The high physical and mechanical properties, as well as the thermal and electrical conductivity, of refractory metal composites make tungsten copper alloy very suitable for die inserts and electrode facings, flash and butt welding dies, and hot upsetting. They can also solve heat balance problems.

2.Electrical Contacts
Electrical contacts are subjected to extreme mechanical and thermal stresses during operation. For fractions of a second, temperatures rise to several thousand degrees as a result of the arcing. Our tungsten copper materials are used owing to their unique physical properties.

3.EDM and ECM
Tungsten copper alloys are used worldwide for EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) electrodes. All material is manufactured by the press, sinter, and infiltrate process. Virgin tungsten powders are used, resulting in a consistent homogeneous material giving high and even burning rates. Tungsten copper is used in plunger/sinker applications where intricate definition is required, especially in tungsten carbide.

4.Spaceflight field
Tungsten copper alloy performance excellent as heat resistant, ablate resistant, high intensity, high density and self cooling, it is widely used in spaceflight field.

5. Electrodes for Spark Erosion
Our WCu electrodes are best suitable for EDM machining of those materials.
Types of product: rods, tubes and plates.
