If you can dream it, we can build it. Our technical expertise starts at the beginning of the MIM process. First, in-house metallurgists and material scientists analyze your application goals and requirements. We consider strength, corrosion, durability, and resistance and select the most suitable materials to develop a suitable feedstock.
Although we can process BASF/ Catamold® feedstock, APP has a unique ability to select and manufacture metals and alloys that go beyond the common standards and outrival off the shelf products. Our mechanical properties exceed MPIF Standard 35. With the capability to both develop and manufacture components, we can seamlessly transfer the process of developed material directly into the manufacturing phase.
Material selection is a vital step in the design process. If you want your final product to outperform the competition, APP has got you covered. We offer:

This guide walks you through typical material properties for MIM low-alloy steels. Low-alloy steels exhibit superior mechanical properties to plain carbon steels due to the addition of alloying elements. MIM low-carbon steels can achieve higher densities and greater mechanical properties over castings. Need help choosing the best option? Let our application experts take a closer look.
