Draycast specialises in manufacturing high-quality bronze sand castings through advanced sand casting techniques. Utilising both green sand moulding and airset mould systems, we ensure precision and durability in every bronze casting we produce. Our expertise extends across a spectrum of bronze alloys, each with unique mechanical and chemical properties. From traditional leaded gunmetals like LG2 & LG4 to versatile aluminum bronzes such as AB2/C95800, we cater to diverse industrial needs. We cast various metals daily, and we excel in using specialised bronzes for specific applications, guaranteeing tailored solutions to meet your requirements.
The alloys we use are detailed below and please follow the links to the various individual pages for a more complete description, chemical analysis and application notes for each alloy. We can source other alloys as required but these are what we use on a daily basis.
