Our casework is constructed from aerospace grade aluminium alloy which contains Magnesium and Zirconium compounds and is chosen for its damping and structural properties. To create a high quality, elegant aesthetic, we provide a selection of finishes which serve to protect the metal surfaces and present the turntable in a light which befits its quality and bespoke nature. Custom finishes are also possible. Here are some examples of the finishes available.
Our Titanium finish uses a far more complex specialised surface treatment technology and coating process. The surface finishing technology is an extremely hard ceramic-like material, often used as a physical vapor deposition on aluminium alloy components to improve the substrate’s surface properties. Applied as a thin coating, it is used to harden and protect surfaces and adds a decorative “golden hue” to the appearance. It is non-toxic coating which is even safe for medical implants. We also use a proprietary electroless process to add additional alloy metals to soften the finish to achieve a satin look instead of bright shiny polished finish. The process involves multiple service providers each performing highly specialised steps to prepare the substrate for the next additive process. It requires an extremely clean work-space, process monitoring and filtration standards.
When Dohmann Audio components are processed, strict procedures are followed to ensure that only the parts from the one turntable are processed through the surface coating tanks and chambers at the one point in time. Although this process is costly, it prevents cross-contaminants from entering the tanks after the surface coatings have been prepared for deposition onto our parts. This exclusivity ensures the highest standards are achieved and contributes to the cost of the titanium finish vs the standard finishes. The additional steps to apply the coating involves several highly specialised technology providers from the Australian aerospace industry.
