Alumina (Al2O3) ntchito zazikulu
Zigawo za zida zopangira semiconductor (zigawo za cavity, ma flanges otchinjiriza, zida za etching, zotchingira zopindika);Zigawo zogaya (classifier, air flow mphero, mikanda mphero);General mafakitale zigawo zikuluzikulu (laser processing makina nozzle, yozungulira kutsinde, kubala);Kulondola kwambiri, kulondola, zida zazitsulo zosagwira kutentha (zoyikapo, zokonzera msonkhano);Valani mbali zosagwira ntchito (wodzigudubuza wamakina ojambulira mawaya, waya wachitsulo, njanji yowongolera);Zida zamagetsi zamagetsi (ma insulators, gaskets, bushings).
