Webster-B75鉗式硬度計美國Webster韋氏硬度計
Webestrt(B、B75、BB75)韋氏硬度計(鉗式硬度計)是鋁合金型材、鋁合金門窗、鋁加工行業、鋁制品企業必不可少的儀器,該儀器在鋁合金生產、鋁型材生產、鋁型材門窗生產、玻璃幕墻生產中得到了廣泛的應用。
* 確定工件有無熱處理,檢查熱處理效果,判定材料力學性能是否合格。
* 確定工件是否為不適當的合金加工而成,判定材料合金成分是否合格。
* 測試不便送到實驗室的過長、過重工件或裝配件。
* 用于生產檢驗、驗收檢驗和質量監督檢驗。
B型主要應用于鋁和鋁合金(系列1100—7075)的硬度測量。亦可以用來測量某些鋼和銅合金的硬度,其測量范圍為:
鋁和鋁合金 HRE 24-110
鋼 HRB 10-98
銅合金 HRF 60-90
B—75型主要用于測量鋼和較硬的合金(系列2024,6061和7075),也可以從退火狀態到全硬狀態的銅合金,其范圍為:
鋼: HRB 20—100
銅合金:HRF 15—90
鋁合金:HRE 83—113
BB—75型主要用于測量電解銅及硬度較低的銅。同時可用來測量其他類似的材料,其范圍為:
銅: HRE 18—100
功能特點:
* 體積小,重量輕,可單手操作,便于攜帶。
* 能測量多種外形。
* 操作簡單,操作技能對讀數無影響。
* 測值可通過查表換算成常用的維氏(HV)、洛氏(HRF、HRE)硬度值或抗拉強度(σb)值
Webster-B75 clamp durometer American Webster webster hardness tester
Webestrt (B, B75, BB75) webster hardness (clamp durometer) is an important instrument of aluminum alloy profiles, aluminum alloy doors and windows, aluminum industry, aluminum products enterprises, the production,in the aluminum alloy aluminum production, aluminumdoors and windows, glass curtain wall productionproduction in a wide range of applications.
* to determine the workpiece without heat treatment, heat treatment effect examination, determination of mechanical properties of materials are qualified.
* to determine whether a workpiece is not appropriate alloy processing, judging whether qualified material alloy composition.
* test inconvenience to laboratory too long, heavy workpieces or fittings.
* for production testing, acceptance testing and quality supervision and inspection.
B mainly used in aluminum and aluminum alloy (1100 - 7075) hardness measurement. Also can be used to measure some steel and copper alloy hardness, its measuring range:
Aluminum and aluminum alloy HRE 24-110
Steel HRB 10-98
Copper alloy HRF 60-90
The B - 75 type is mainly used for measuring steel andhard alloy (20246061 and 7075), also copper alloy fromannealing state to a full hard state, its scope:
Steel: HRB 20 - 100
Copper alloys: HRF 15 - 90
Aluminium alloy: HRE 83 - 113
The BB - 75 type is mainly used for measuring theelectrolytic copper and low hardness of copper. At the same time can be used to measure other similar material,its scope:
Copper: HRE 18 - 100
Function characteristics:
* has the advantages of small volume, light weight, single hand operation, easy to carry.
* can measure various shape.
* has the advantages of simple operation, operation skills and no effect on the readings.
* values through the Vivtorinox table converted intocommon (HV), (HRF, HRE) Rockwell hardness valuesand tensile strength (σ b) valu
