Improvement in Mechanical Strength of Bonded Neo Magnets

Improve room temperature ring crush strength

Crush strength was measured without lubricant.
Magnet density was measured on OD20.8*ID18.6*H5mm ring magnets.

Increase in epoxy results in better cross-linking, reduced porosity and hence helps to increase ring crush strength.


Improve high temperature mechanical strength

Novolac epoxy can help to improve the crush strength and stress rupture strength at elevated temperatures relative to DGEBA epoxy.

The creep rupture strength can be further improved with powder surface treatment (AA4).
