5 Examples of Uses Where Non-Metallic Parts Win Out Over Metals

When Metal PARTS Fail

At Red Seal Electric Company, we specialize in the fabrication of non-metallic insulating parts. With our deep expertise working with composites, we might be a bit biased.

But non-metallic materials aren’t just an alternative to metal; oftentimes, they’re the superior choice. Thanks to the vast range of properties found in composite materials, they’re often better suited for demanding environments.

Environments Where Non-Metallic Materials Win Out

1. When electrical insulation is critical.

Simply put, metals conduct electricity. Non-metallic materials like phenolics, fiberglass, or composites offer natural electrical insulation. These parts can meet high dielectric strength requirements, especially in electronics and aerospace applications, where metal would pose a safety risk.

2. When weight reduction is essential.

On average, non-metallic materials are 60-80% lighter than their metal counterparts. These savings in weight can drastically improve fuel efficiency and reduce load stress in industries like aerospace and automotive. 

3. When corrosion is a dealbreaker.

In wet environments, exposed metal parts are prone to rust and corrosion. Similarly, metal parts that are frequently exposed to chemicals, such as food processing equipment that must withstand regular sanitation, can also degrade over time. Coatings and alloys can help, but they are expensive and require upkeep. On the other hand, many non-metallic materials resist corrosion, making them more cost-effective and longer-lasting. 

4. When vibration must be reduced.

Rigid metal parts are prone to loud vibrations. In applications like household appliances, where low noise is a must, non-metallic materials are ideal. They naturally reduce vibration and don’t rattle under repeated impact.

5. When thermal insulation is required.

If there’s one spot where non-metallic parts really outshine metal alternatives, it’s in thermal insulation. Metal parts transfer heat easily, but non-metallic parts can handle high temperatures up to 2300ºF or more without conducting heat to supporting parts.
