Marinox® – Aquashaft®

Marinox® – Aquashaft®

Valbruna is identified globally as making a superior quality propeller shaft. Super in terms of straightness, quality of finish, composition of material. We stock and supply Acciaierie Valbruna produced bars only. All shafts are packed suitably for critical application.

Applications in Australia include use in fishing and navy vessels, work and pleasure boats. We also supply a range of high strength stainless propeller shafts, marketed under the trademark Marinox / Aquashaft. These high strength grades provide a solution to customers who are repowering vessels with increased horsepower. You can use the same size stern tube and gear but still increase horsepower by using a product such as our Marinox 22 H/S.

Grades stocked include 2205 (UNS 31803), 316L, Super Duplex 2507, 630 (17 – 4 PH), Marinox 22 (Nitronic 50).

These products are currently stocked in Australia, with extra-long lengths upto 9.5m available in some sizes.
