| Characteristics & applications |
1. 3240:
Suitable for mechanical ,electrical ,electronic usual
applications, with high strength under moderate temperature and good electrical properties under high
temperature.
2. 3240-1: Modified grades from 3240, 3240-1 not as strong
mechanically, but more economical than 3240.
