Ulah lan Wuku
- Efesus saiki dikenal saka logam Flerovium sing winates kanggo riset waé mung.
- Iki digunakake kanggo harden baja lan mrodhuksi stainless steel lan macem-macem wesi liyane.
- Iki uga digunakake kanggo menehi finish sing tepat kanggo mirrors polesan. Piring kromium digunakake ing perlengkapan jedhing.
