Permanent Magnets

Specifications

            Flaw Finder permanent magnets are a simple tool for the effective, easy and quick part magnetization for detection of surface and subsurface defects. The concept of the Flaw Finders enables the use for testing under conditions that make the application of electromagnetic yokes impracticable or are excluded for safety reasons.

 

Flaw Finder Type A permanent magnet
Flaw Finder Type A meets the requirements of ASTM E709-95 and ASTM E1444 and is an ideal instrument for magnetizing of small-sized parts and weld joints. It consists of 2 permanent magnets connected with a magnetic conductor.
Lifting force: >30 kg (294 N)
(ASTM E1444 requires min. 22.5 kg)
Magnetic material: neodymium-iron-boron
Flaw Finder Type N permanent magnet
The Flaw Finder Type N meets the requirements of ASTM E709-95 and ASTM E1444, it consists of a central permanent magnet with attached flexible magnetic conductors. These flexible poles serve for optimal fit to surface geometry. The magnetizing force is tested by TB10 test block.
Lifting force by pole spacing 100-150 mm: >27 kg (265 N),
(ASTM E1444 requires min. 22.5 kg)
Magnetic material: neodymium-iron-boron
ТВ-10 Weight Lift test bars
TB-10 is used for calibration and certification of AC and DC electromagnets as well as permanent magnets to the following specifications by testing their pull-off strength. The bar weight is stamped on each bar and is traceable to NIST
specifications. The TB-10 bars are provided with a central drilling so that they can be screwed together to perform DC yokes testing. Without artificial defects.
Complies with: ASME Section V Article 7, ASTM E 709, ASTM E 1444, MIL-Std.271 E&F NAVSEA-TB-T9074-AS-GIBO 10/271
Weight: 10 lb (4.5359 kg)
ТВ-10 SP Weight Lift test bars
TB-10 SP serves for calibration and certification of AC electromagnets. The bar weight is stamped on each bar and is traceable to NIST. Contains artificial defects.
Complies with:
ASME Section V Article 7, ASTM E 709, ASTM E 1444, MIL-Std.271 E&F
NAVSEA-TB-T9074-AS-GIBO 10/271
