Please note that, while these materials are considered ultralight and super strong, they may not be the most cost-effective option for all products. The selection of material also depends on the requirement of the product, cost and ease of processing. Additionally, not all of these materials are inexpensive and easy to process, carbon fiber and Graphene for example are hard to process and expensive.
