Unit 11
Properties of materials
I need an appropriate material for a new generator casing. Do you have suggestions? The most important factor is hardness. I want something strong, but still malleable. I need to form it into a precise shape. It should be ductile with a tensile strength. A brittle material might break during the manufacturing process. This casing requires a high yield strength. It will be exposed to a lot of stress and heat. That means that the proportional limit and elastic limit should be high. I don't care whether the material is synthetic or natural. Cost is a factor, so whether is the less expensive option is best. Luster is not important either. The generator’s appearance is not a concern.

Also, the material should be an insulator. There will be several electrical systems nearby. A conductor might cause them to interfere with the generator. What do you think I should use?

Thanks,
Heidi Simons
