Ibikoresho: Icyuma cyimpeshyi (65mn, 60si2mna), ibyuma bidafite ishingiro (304316l), ibyuma bidafite ishingiro (420)

Igice: Ibice igihumbi

Gukomera: HRC: 44-51, HY: 435-0

Kuvura hejuru: Blackening

Ibikoresho: Icyuma Manganese (65mn, 1566)

Ibiranga ibikoresho: Nigikoreshwa na karubone nini yicyuma, gifite imbaraga nyinshi, gukomera, ubukana, nubunini ugereranije na 65. Diameter ikomeye diameter muri rusange 30-50mm mumazi na 16-32mm mumavuta. Ifite ubushishozi bwo kwishimira no gushaka gukabya umujinya mugihe cyo kuvura, kandi bikunze kuvunika mugihe cyamazi. Amavuta yo gutangiza muri rusange. Amazi akwirakwira mu bice birenga 80. Gukonjesha amavuta: Nyuma yo gushinga amavuta: NYUMA YO GUTANDUKANYE, ariko ubushobozi bukonje ni buke, kandi imikorere yo gusudira ni ikike. Ibyuma bisanzwe bikoreshwa nyuma yo kuzimya no kubaramba ku bushyuhe bwo hagati. 3-16
