Is the bismuth molybdenum bismuth alloy wire the main wire cutting electrode wire? A group of research materials will tell you later. We start with the “six hopes” of the wire cutting industry. There are so many expectations in the wire-cutting boss: one is looking forward to the wind; the second is not changing the liquid; the three expecting the meter does not turn; the fourth is expecting the rent to be halved; the five hope that the sun does not fall; the six-hundred machine turns over 10,000! However, the wire-cutting master and the little master said after hearing that they did not say the "five expectations" in the back. We first realized the "first hope", that is, when the "electrode wire is not easily broken", other.

potassium containing tungsten bars are raw materials for making light source materials, high-temperature heaters and high-temperature resistant components. The traditional production method is to add silicon, aluminium, potassium and other elements into tungsten oxide powder first, then reduce the tungsten oxide powder doped with these elements and wash it with hydrochloric acid and hydrofluoric acid to obtain doped tungsten powder, then doped tungsten powder. After being pressed, the strips are sintered and sintered to obtain potassium containing tungsten bars.

Recently, China's newly developed TMH20/15MN large radial precision forging machine was successfully tested at one heat load, and the first qualified high-end bar was forged. The successful test of the radial precision forging machine marks that the core manufacturing equipment of high-end pipe in China will no longer be easily "card neck"! However, this also means that China has successfully broken one of the technical barriers that have long been completely monopolized by foreign countries - large radial precision forging machine preparation technology!

Tungsten trioxide (WO₃) is a typical n-type semiconductor material, which has broad application prospects in electrochromic devices, gas sensors and photocatalysts. Particularly in the field of photocatalysis, WO₃ has a narrow band gap (2.4-2.8eV) compared with other semiconductors (such as titanium dioxide and Bi₂O₃), which can utilize solar energy more effectively.
