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. Sheets, rods and bars of tungsten copper alloy are available as well.
Applicatioins of tungsten copper sheets
Tungsten copper alloy bars are used worldwide for EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) electrodes. All the tungsten copper alloy is manufactured by the press, sinter, and infiltrate process. Virgin tungsten powders are used, resulting in a consistent homogeneous material, which gives the high and even burning rates. Tungsten copper is used in plunger and sinker. Applications where intricate definition is required, especially in tungsten carbide.
The advantages of the tungsten copper bars
1. The high heat resistant.
2. The better ablate-resistant.
3. The great electrical conductivity
