Tips

memory

金 (metal) radical + 乌 (wū, 'crow / black') as phonetic. The 乌 hint also fits semantically: tungsten ore (wolframite) looks dark and crow-black.

culture

China holds about 80% of the world's tungsten reserves. 江西 province is the historical mining heartland.

Components

radical

钅 jīn

metal; gold

钅 is the left-side simplified metal radical (金 in standalone form). It indexes 钨 (tungsten) in the metals family alongside 铁 (iron), 铜 (copper), 锌 (zinc), 铝 (aluminium). Modern Chinese created element names systematically by pairing 钅 with a phonetic - a clean nineteenth-century invention slot.

phonetic

乌 wū

crow; black

乌 supplies the sound exactly - same initial, rime, tone. The same phonetic also drives 呜 (whimper), 邬 (surname), 坞 (dock). The crow-black imagery is faintly apt: tungsten ore (wolframite) is a heavy near-black mineral, and tungsten filaments glow only after fierce heating.
