PM aluminum alloy is an emerging technology in China, and only a few enterprises in Europe, America, Japan and other countries have mastered it. The company has solved a series of core problems in aluminum alloy powder metallurgy, using self-developed new processes to produce aluminum alloy powder metallurgy products, covering 6 series, 2 series, 7 series aluminum alloys and composite materials. Its mechanical properties are far higher than die-casting aluminum alloys and not lower than machined aluminum alloys, fully utilizing the advantages of high efficiency, low energy consumption and low cost of powder metallurgy, and can achieve commercial production of low-cost and high-performance products. A production line with mass production capability has been built. The target product includes small and micro synchronous wheels, small module gears, end caps, and shaped parts, suitable for product parts that require weight reduction, rust prevention, heat dissipation, and non-magnetic properties. It can be used in fields such as micro transmission, small compressors, lighting fixtures, and drones.
