provide ANSI Standard Copper Tungsten Bars W85 W75 Machined Tungsten Copper Alloy CuW Bars The feature of the tungsten copperb bars Tungsten copper (copper tungsten, CuW, or WCu) alloy is a pseudo-alloy of tungsten and copper. 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.Tungsten copper 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. The tungsten copper bars have the better heat resistant and great ablate resistant. At the meantime, the tungsten copper bars have the high intensity and high density. The tungsten copper alloy has the excellent thermal and eletrical conductivity. And the tungsten copper alloy is easy to be machined. The bars 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.

Polished Tungsten Copper Alloy Copper Tungsten Bricks 5mm to 100mm Thickness Tungsten opper alloy brick is also called tungsten copper brick (tungsten-copper, Cu-W, or W-Cu), which is a pseudo alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the tungsten copper alloy brick material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure of tungsten copper brick is therefore rather a metal matrix composite than a true alloy. Tungsten copper alloys are used where the combination of high heat resistance, high electrical and/or thermal conductivity, and low thermal expansion are needed. Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks. As contact material the alloy is resistant to erosion by electric arc.

Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in power, power distribution and power consumption. Broadly speaking, contactor refers to an electrical appliance that uses the current flowing through the coil to generate a magnetic field and close the contact in order to control the load. main features The AC contactor uses the main contact to open and close the circuit and the auxiliary contact to turn on the control circuit. The main contact is generally normally open contact, while the auxiliary contact often has two pairs of normally open contact and normally closed contact. Small contactors are often used as intermediate relays to cooperate with the main circuit. The contact of AC contactor is made of silver tungsten alloy, which has good conductivity and high temperature ablation resistance. The power of AC contactor action comes from the magnetic field generated by AC through the coil with iron core. The electromagnet core is composed of two "mountain" shaped young silicon steel sheets. One of the fixed iron core is sleeved with coil, and the working voltage can be selected. In order to stabilize the magnetic force, a short-circuit ring is added to the suction surface of the iron core. After the AC contactor loses power, it returns by spring. The other half is a movable iron core, whose structure is the same as that of a fixed iron core, which is used to drive the closing and breaking of the main contact and auxiliary contact.
