Non metals?

Question

what advantages do non metals have over metals?

Answer 1

to go with the guys above, certain nonmetals, like refractories, can be used at high elevated temperatures. Nonmetals give different electrical properties than metals and need to be used over metals.

Answer 2

As non-metals and metal come in many varieties with different properties, and those properties may be advantageous or disadvantageous depending on what you want to do with the material, there is no simple answer.

If you want electrical insulation, most non-metals have the advantage of not conducting electricity.

If you want a window, some non-metals are transparent, whereas no metal is.

If you want jewelry, plastic is a lot cheaper than gold.

etc.

Answer 3

There's a few answers for this one.
1. Metals corrode (rust)if they're exposed to certain conditions, whereas a synthetic material such as plastic or composite will not.
2. A material such as composite is usually 4 times stronger than steel, and only half the weight. It's expensive to manufacture, but it literally lasts forever. Metals are more difficult to machine due to residual stresses and fatigue qualities, plastics and composites can be machined to customization.
3. Metals are typically more brittle than plastics, and are less resistant to impact. That's why certain high impact structures, like bicycles have Kevlar(composite) coating.
4. Plastics can return to their original shape if they are bent out of shape, where metals will retain the new shape they've been molded or bent to.

Hope this helps

Answer 4

Metals and A metals.33% metals and 67% Ametals.Elements,compounds and Mixture are matter.

Answer 5

1) as almost all nonmetals are non conductive chance to electro magnetic interference is very low...( so great chance in electronics

2)its conductivity is almost independent of temperature

3)light in weight

Answer 6

metals are stronger
