Deciding on the best material for your part can be a challenge. Generally it is best to look at the properties of each material. For example, if price is the only factor, choose the lowest cost material. If price and hardness are most important, select the material that has the best combination of those two values. Metals allow for parts of higher tolerance than plastics and some plastics can warp over time due to moisture absorption.
