Strong, hard insulator

[eromlignod]

Hey guys:

I have an application for a project where I need an insulating
material that must have a high tensile strength and hardness. It is
replacing a part that is normally made from brass, so that is the kind
of strength and hardness I am looking for. I am currently using
Delrin acetal, but it is really too weak and soft for my application.

Does anyone know of a non-conducting material that is comparable to
brass?

The voltage is very low (2 or 3 volts max.), though the conductors are
fairly close together (.150" apart, .030" dia. conductors). So
dielectric strength does not need to be really high. Thanks for any
help you can provide.

1. Passivated aluminum - hard & non-conductive surface, strong tensile
strength
2. Sandwich brass between suitable isolating sheeting.
3. Coat brass with epoxy resin layers

Look into G-10 it is the same think that circuit boards are made of. I
bought a 4'x4'x4" piece several years ago. I used the G-10 for bracing in an
old 4000 amp 480V pull section of a electrical service. We removed the old
metal bracing and replaced it with G-10. Still have about half of it left.

It also has good properties when it comes to water as well.
