Latest Patents

Ma’s patent, “Thin-walled composite pipe with high thermal conductivity, and preparation method and application thereof,” describes a process for producing a pipe from aluminum nitride particle and zinc-aluminum 27 alloy (AlN/ZA27).

The method subjects a composite billet to multiple passes of reciprocating extrusion at 250–350°C before loading it into a pipe extrusion die. The billet is heated with an ascending temperature gradient along the extrusion direction, from the billet toward the die outlet, within the same temperature range. After being held at a preset temperature, the material is extruded at a rate of 0.1–0.5 mm/s to form the thin-walled composite pipe. The patent also describes the resulting pipe, which comprises AlN particles and ZA27 alloy.
