Inopisa yekutengesa yeChina yepamusoro mhando yakagadziridzwa ASTM Beryllium Copper Roti / Copper Bar
Yakatsaurirwa kune yakasarudzika manejimendi emhando, vatengi vedu vane ruzivo vanowanzowanikwa kuti vakurangarire mwero wekupisa kweChina Mitero inonzwisisika uye zvigadzirwa zvine mwero, zvigadzirwa zvedu zvinoshandiswa zvakanyanya nemaindasitiri uye mamwe maindasitiri.
Yakatsaurirwa kune yakasarudzika mhando yemhando uye yevatengi vematengi, vatengi vedu vane ruzivo vanowanzo kuwanikwa kuti vakurukure zvako zvaunoda uye vimbiso yakazara yemutengi mufaro we1kg trass bar, China bar bar, Mushure memakore ekukura, isu takagadzira kugona kwakasimba mugwaro rekusimudzira kwechigadzirwa uye rakasimba remhando yepamusoro kuti rive nechokwadi nemhando yepamusoro uye sevhisi. Nekutsigirwa kwevazhinji vakareba vatengi vane mari yekubatira, zvinhu zvedu zvinogamuchirwa pasi rese.
