Detailed Introduction Of cobaltalloy Copper Tungsten

  • Copper Tungsten alloy material is a metal composite material, it is called tungsten-copper alloy, as the name suggests is because it is made of two kinds of tungsten and copper materials, and this composite material can also be widely used in many Industry, so today we take a look at what areas in our country can be frequently used tungsten-copper alloy it?

    According to reports, "National Nonferrous Metals Mining Conference and 2012 (the tenth) Nonferrous Metals Mining Forum" will be held from July 6 to July 7 at the Beijing International Convention Center. The meeting aims to mobilize the entire industry to further understand the importance of mining work on building a non-ferrous metal industrial power, and create a new situation of non-ferrous metal mining reform and development. Mining Conference and Forum are rich in content, not only important speeches led by ministries and commissions, but also excellent reports from academicians and experts. The meeting will also solemnly commend the advanced units for the development and utilization of nonferrous metal mineral resources, award the "China Nonferrous Geological Prospecting Achievement Award" and hold the signing ceremony of relevant cooperation projects.

    According to the composition of the tungsten alloy can be divided into W-Ni-Cu, W-Ni-Fe two series and W-Ni-Cr, W-Ni-Mo, W-Ni-Co and other alloys. W-Ni-Cu alloy is mainly composed of W, Ni, Cu powder sintered by pressing. Among them, the content of W is generally 80% to 90%. Ni and Cu binders are added to form a two-phase alloy after liquid phase sintering, and the density is close to the theoretical density.

    The alloy, in addition to W, Ni remaining content is the content of copper. Copper in the alloy can improve the strength and ductility of tungsten alloy. W-Ni-Fe alloy is composed of W, Ni, Fe powder sintered by pressing. One of the most tungsten content, reaching 80% to 90% and nickel, iron plays the role of binder. After the liquid phase sintering to form a two-phase alloy, density and theoretical density similar. Nickel is an indispensable element in the liquid phase sintering process. The content of nickel is generally 0.5% ~ 12%. If it is more than 12%, the heat resistance and corrosion resistance of the cobaltalloy will be reduced. The content of iron is generally between 0.5% and 8%, and if it is more than 8%, the brittleness of the alloy will increase.
