True or False: Non-graphite pencils can cause corrosion and damage to assembly materials.

The assertion that non-graphite pencils can cause corrosion and damage to assembly materials is indeed false. Non-graphite pencils, especially those made with materials such as plastic or wood, generally do not have the properties that lead to corrosion. Corrosion typically results from the presence of moisture and certain metals that can react with environmental conditions or substances.

In most assembly settings, using non-graphite pencils does not pose a risk for damaging materials, as they are designed to be safe for a wide range of surfaces, including metals and composites commonly used in aerospace applications. These materials are also non-reactive and do not contain substances that are known to cause corrosion. Thus, using a non-graphite pencil is unlikely to introduce any harmful agents that would compromise the integrity of assembly components.
