AATi Foundry has specialised in sand castings for resistance welding and electrical switchgear for over 50 years. This experience supports high-purity castings for transformers, busbar terminations, catenary parts, switchgear and high heat-transfer parts.
Close control of casting and heat-treatment variables supports demanding conductivity and mechanical properties, often over 98% IACS for HCC1 and 90% for CC1. Complex water-cooling tubes can be incorporated using Nickel and Nimonic Alloy prefabricated tubes.
