Quality standard and advantages of aluminum billet products

In order to produce high cleanliness and quality aluminum billets, Taiwan Hodaka uses high-purity aluminum ingots as the raw materials (Al>99.85%, in contrast to the common 99.70% purity). We use computerized Rotary Flux Injectors and Electromagnetic Stirrer Systems in our melting furnaces to remove dross and stir the melt and the degasser system. Dual-staged CFF and tube filtration are used to effectively remove hydrogen and inclusions in the melt. The purification processes are complemented by In-line Metal Cleanliness Analyzers and In-line Hydrogen Analyzers to provide real-time monitoring of melt cleanliness and hydrogen contents. We also use AirSlip technology to cast aluminum billets with thin segregation layers, highly uniform microstructures, and excellent surface quality. Lastly, proper homogenization is performed to remove segregation and produce stable and quality aluminum alloy billets (see specifications below):
