A metal/polymer hybrid featuring nanotechnology aimed at extremely lightweight components was introduced at K 2007 today by DuPont Engineering Polymers and partners Morph Technologies of Toronto, Canada; Integran Technologies, of Pittsburgh, PA; and PowderMetal Technologies of Carlsbad, CA. Key to the technology is a new proprietary process called MetalFuse that applies precise amounts of nanometal to molded plastic components. Parts are said to have the stiffness of aluminum or magnesium but with better strength. Grain sizes of the metals are 1000 times smaller than conventional metals. “Nanocrystalline nickel or nickel-iron are high-performance metals that are two to three times stronger than normal steel and are also significantly harder, with better wear and friction performance,” says Gino Palumbo, president of Integran Tehcnologies. Initial development will focus on selected applications in the automotive, consumer electronics, and sporting goods markets.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
