Magnetic capacity measurement

General magnetic capacity measurement
a) Magnetic Properties: Br, Hcb, Hcj, (BH)max, Hk, Ms, μrec, Hk/ Hcj etc.
b) The test instrument used is the Hysteresisgraph tester.
c) Hcj value between 50 and 20,000 Oe can be measured.

Magnetic properties at high and low temperatures
(-40 to 250 °C): Properties tested at any temperature as above within the specified range.

Reversible temperature coefficients
Measured and calculated for any range desired within the specified temperature ranges.

Magnetic field waveform distribution
Data and graphic output can be provided as linear, planar or rotary.

Fluxmeter measurements
Magnetic dipole moment, total magnetic field output and error angle measurements. Several measurement systems are available with the Helmholtz coil; highly flexible manually operated systems and automated systems.

Gauss measurements
Single measurements at specified locations or measurements using C-fixtures, yokes or of customer-specified design.

 

Physical and Corrosion resistance Test capacity

Salt spray
This is a characteristics test performed to ASTM B-117. Results are usually expressed as “failure time”. Photographs tested can also be provided.

High-temperature & high-humidity measurement
Test conditions are typically set between 80 and 95 ºC and between 90 and 100% RH. The most common setting is 90 °C and 95% RH. This is usually a characteristics test.

Autoclave for uncoated magnets
Such test is also called PCT test, is a weight-loss test performed at 2 atmospheres, 150°C and 100% RH. The duration is 96 hours, but can be adjusted according to customer requirements.

Autoclave for coated magnets
This is a characteristics test looking for lack of failure at specified test duration. Test conditions can be selected ranging from two atmospheres, 100% RH to HAST test conditions.

Physical strength
Our Crushing strength tester can be configured for tensile (pull), 3-point bend or for peel testing.
