AL5718 Al 12Si

Al 12Si Powder Description:

Al 12Si Powder is a gas-atomised aluminium alloy powder with a silicon content of 12 weight-%. This material is highly versatile and is well-suited for the repair and build-up of components made from aluminium or magnesium alloys, as well as the repair of worn engine parts. Due to its simple eutectic system with a low melting temperature of 577 °C, silicon plays a critical role in lowering the melting point while simultaneously improving flowability, specific weight, and coefficient of thermal expansion. Additionally, the nearly pure silicon content significantly enhances the hardness of coatings produced from this powder, leading to improved wear resistance. Coatings made from Al 12Si Powder exhibit a higher hardness and slightly increased density compared to those made from pure aluminium powder. With a particle size distribution suitable for atmospheric plasma spraying applications, Al 12Si Powder represents a reliable solution for various industrial requirements, promising effective dimensional restoration and enhanced performance across diverse technical applications.
