Tungsten carbide Zvigaro uye Mavharuvhu anoiswa mune akasiyana oiri uye gasi akaiswa, oirifield mavharuvhu, Marasha kemikari indasitiri. Mumamiriro ekushanda kwenguva yakareba uye yakaoma, tungsten carbide valve ndiyo yakanakisa sarudzo. Panguva imwecheteyo, tungsten carbide valve uye chigaro ine zvinotevera zvakanakira: kuderera kweruzha uye kukwirira kupfeka-kupikisa; kuomarara kwepamusoro, simba rekumanikidza rakakwirira; Kugadzikana kwakanaka kwemakemikari uye kuderera kwesimba kusimba; yakaderera kuwedzera coefficient; conduction kupisa uye electric conduction.
