Brass is a substitutional alloy of copper and zinc, extensively used in Australian construction for hardware, fittings, and architectural applications. Available in various grades including free-machining brass (C360/C385), dezincification-resistant brass (C352), and architectural brass (C260/70-30), each optimised for specific applications. The material combines aesthetic appeal with functional properties including natural antimicrobial action, good strength-to-weight ratio, and excellent formability. Australian specifications typically require compliance with AS 2345 for dezincification resistance in water contact applications.
