布氏硬度采用的試驗力大,壓痕直經(jīng)也大,適合具有大晶粒金屬材料的硬度測試,如: 鑄鐵,有色金屬及合金,各種退火、調質處理后的鋼材,特別是對于較軟的金屬,如純鋁、鉛、錫等。
Brinell hardness test which adopts heavy testing force and shows large indentation is apply to measure hardness value for big grain metal materials such as casting parts, nonferrous metals and alloy, various tempered steel, hardening and tempering steel, specially for soft metal such as pure aluminum, lead, tin, etc.
