China’s leading manufacturer of SiC particle reinforced aluminum matrix composites: DLLG Advanced Materials Technology Corporation has successfully realized the commercial production of nano-titanium diboride/TiB2 particle reinforced aluminum matrix composites.
Aluminum is light and easy to process, and is an excellent structural material, but its soft characteristics limit its bearing conditions; while ceramics have high hardness and rigidity, but are brittle and difficult to process.
How to achieve the complementary properties of aluminum and ceramics?
Combining aluminum and ceramics organically, learning from each other’s strengths and making up for their shortcomings, and making a composite material with a combination of rigidity and flexibility, can make aluminum materials achieve a leap in performance.
The as-cast grain size of the material is refined from the original millimeter to tens of microns, and the average size of the in-situ self-generated ceramic particles is less than 100 nanometers.
Nano-titanium diboride/TiB2 particle reinforced aluminum matrix composite material is made into the base material, which can not only be remelted, diluted and secondary alloyed to prepare new materials; it can also be used as an additive to modify existing materials to improve performance.
At present, the aluminum-based composite materials reinforced by nano-titanium diboride/TiB2 particles and the modified aluminum-based composite materials have been used in many projects such as cables, fasteners, extruded profiles, and die castings. To meet high-end quality requirements, the technology has also achieved very good results in other scenarios such as power batteries and laptop casings.
Nano-titanium diboride/TiB2 particle reinforced aluminum matrix composite technology can bring innovations in industries such as overhead conductors, automobile manufacturing, and rail transit.
