適用范圍
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(diào)質(zhì)處理后的鋼材，特別是對于較軟的金屬，如純鋁、鉛、錫等。
HBE-3000 Electronic Brinell Hardness Tester with 10 steps testing force is able to measure hardness values with each 10 Brinell hardness scales. The instrument adopts circuit type sensor added with control system, thus with high precision, high repetition,reliabilityeasy operation.
Usage Range:.
Brinell hardness test which adopts heavy testing forceshows large indentation is apply to measure hardness value for big grain metal materials such as casting parts, nonferrous metalsalloy, various tempered steel, hardeningtempering steel, specially for soft metal such as pure aluminum, lead, tin, etc.
