General Information
LM6 aluminium casting alloy is renowned for its exceptional corrosion resistance and superior castability, making it a excellent choice across industries. Its high ductility allows for easy shaping and modification, ensuring versatility in various applications. Whether utilized in sand casting, permanent mold casting, or die casting processes, LM6 alloy delivers consistent performance. Particularly suited for marine environments, LM6 castings exhibit excellent corrosion resistance and ductility, although they maintain only medium strength and are not heat treatable. While their strength diminishes at high temperatures, their low elastic limit and moderate machinability make them suitable for diverse engineering needs.
Typical Applications
LM6 castings find extensive applications across diverse industries owing to their excellent corrosion resistance and superior castability. Common uses include marine components such as boat fittings, propellers, and marine engine parts, where their ability to withstand harsh marine environments is highly valued. Additionally, LM6 castings are utilized in architectural applications for decorative fixtures and fittings due to their aesthetic appeal and durability. In the automotive sector, they are employed for various engine components and structural parts. Their versatility extends to the manufacturing of electrical enclosures and housings, benefiting from their corrosion resistance and ease of casting. With their wide range of applications, LM6 castings continue to be a preferred choice for industries requiring reliable and durable components.
