At Sunmach we consistently manufacture & export a wide range of Aluminium Bronze Fasteners as like Bolts Nuts, Washers, Screws & Studs / Threaded Rods exactly catering to our customer’s specifications or drawing with assured quality & timely delivery.

Aluminium Bronzes most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulphurous compounds and other exhaust products of combustion. They are also resistant to corrosion in seawater. Aluminium bronzes' resistance to corrosion results from the aluminium in the alloys, which reacts with atmospheric oxygen to form a thin, tough surface layer of alumina (aluminium oxide) which acts as a barrier to corrosion of the copper-rich alloy. The addition of tin can improve corrosion resistance.

Aluminium Bronze Fasteners Applications - Plain bearings and landing gear components for aircraft, Ernie Ball Aluminium Bronze strings, engine components (especially for seagoing ships), underwater fastenings in naval architecture and ship propellers. Aluminium bronzes are in the highest demand in general seawater-related service, water supply, oil and petrochemical industries, specialized anti-corrosive applications, certain structural retrofit building applications. This alloy is most commonly used in applications where their resistance to corrosion makes them preferable to other engineering materials.
