U+9421 "鐡" CJK Unified Ideograph-# Unicode Character

U+9421 "鐡" CJK Unified Ideograph-# is a traditional Chinese character that serves as a variant form of the character for "iron" or "metal," equivalent to the more common character 鐵 (tiě) in standard Chinese. It belongs to the CJK (Chinese, Japanese, and Korean) unified ideograph block and is used in historical or classical texts, often appearing in contexts involving steel, strength, or metallic objects. While less frequent in modern simplified Chinese, it retains significance in traditional Chinese calligraphy, literature, and certain East Asian cultural applications where variant characters are preserved.
