Kusimba kwekusimba kwematanda endarira kunowanzo pakati pe300 ne500MPa (zvichienderana nehuwandu hwezinc), iyo yakakwirira kwazvo kupfuura yemhangura yakachena pa 200 kusvika 300 mpa, ichichengetedza plastiki yakanaka (elongation 15% kusvika 40%). Uhu hunhu hwe "kusanganisa simba uye plastiki" inoita kuti ikwanise kumirisana nemitoro ine simba (sekuzunguzika uye kukanganisa), uye zvakare kuwana yakaoma chimiro kuumba kuburikidza nekutonhora kushanda (kutsika, kukotama) kana kupisa kushanda (extrusion, casting). Semuenzaniso, H62 brass ine 30% zinc (62% copper uye 38% zinc) inoshandiswa zvakanyanya muzvikamu zvemotokari. Iyo ine simba rekusimba re370MPa uye kureba kwe25%, kunyatso kuenzanisa simba uye processability.
