Material
PA-AF (Aluminum Filled)
PA-AF is a blend of polyamide and aluminum powders that produces strong, metallic-looking components that can be easily machined and are resistant to temperatures of up to 130°C. Typical applications include parts for wind tunnel testing in the automotive industry, small production runs, jig manufacturing, as well as educative and illustrative models.
