Aluminum polymer composite: (used for 3d printing objects especially strong)

My understanding of this is that when coated with a layer of aluminum oxide it can withstand impressive loads.

Aluminum polymer composite

From Wikipedia, the free encyclopedia
An aluminum polymer composite (APC) material combines aluminum with a polymer to create materials with interesting characteristics. In 2014 researchers used a 3d laser printer to produce a polymer matrix. When coated with a 50-100 nanometer layer of aluminum oxide, the material was able to withstand loads of as much as 280 megapascals, stronger than any other known material whose density was less than 1,000 kilograms per cubic metre (1,700 lb/cu yd), that of water.[1][2]


Aluminum foam

Spherical aluminum foam pieces bonded by polymers produced foams that were 80-95% metal. Such foams were test=manufactured on an automated assembly line and are under consideration as automobile parts.[citation needed]

Thermal conductivity

Experimentally determined thermal conductivity of specific APCs matched both the Agari and Bruggeman models provide a good estimation for thermal conductivity. The experimental values of both thermal conductivity and diffusivity have shown a better heat transport for the composite filled with large particles.[3]
