To many engineers seeking to replace metal in structural applications, nylon, specifically PA 66, is the default material of choice. Although PA 66 was originally invented as a textile polymer, over the last few decades it has led the adoption of engineering plastics as a material group in critical applications across various industries. Countless metal components have been engineered in PA 66, with a strong record of performance, reliability and cost-effectiveness.

Until recently, engineers have often overlooked other engineering plastic-based materials in favor of standard nylon grades. However, it is important to note that with advances in plastics material technology, other engineering plastics could offer a potential alternative. Today, materials chemists can formulate alternative material solutions that can achieve properties that are equivalent to or better than those of PA 66.

If you’re looking for alternatives to PA 66 but unsure which options are available, we can help. Start with the table below to find out how our top recommended alternatives compare.
