資材 is used in formal and informal contexts. You can use it when discussing business, construction, manufacturing, or any field that involves using physical items. It's common in reports, specifications, and everyday conversation when referring to the things needed to do a job. It is not generally used for abstract concepts or services.

資材 is written in kanji, 資 (shi, meaning "resources" or "assets") and 材 (zai, meaning "materials" or "lumber"). The reading is しざい in hiragana. There are no variations in the okurigana. The word is consistently written using these two kanji.

⚫︎材料 (ざいりょう, zairyou): materials, ingredients (more general). ⚫︎物資 (ぶっし, busshi): goods, supplies (often used in the context of aid or logistics). ⚫︎資源 (しげん, shigen): resources (more broadly, including natural resources).
