Description of Zinc-Aluminium-Cadmium Alloy Bars
Zinc-Aluminium-Cadmium alloy is a shiny, corrosion‑resistant material. It can be easily deformed. In zinc alloys, the aluminium content affects castability, impact strength and other properties, whereas cadmium influences certain concentrations and remains neutral for others.

Applications of Zinc-Aluminium-Cadmium Alloy Bars
Zinc-Aluminium-Cadmium alloy is extensively used in shipping, steel piles, floating docks, bridges, ballast tanks, submarine pipelines, locks and underwater wire ropes. Offshore platforms utilise zinc/aluminium/cadmium alloys in port and marine engineering facilities, underground cables, subterranean oil and gas pipelines, oil well casings, reaction vessels, concrete foundations, heat exchangers, complex water‑gas systems, box‑type coolers, pumps, compressors and chemical towers.

FAQs for Zinc-Aluminium-Cadmium Alloy Bars
Q1. What are Zinc-Aluminium-Cadmium Alloy Bars (Zn‑Al‑Cd) used for?
Zn‑Al‑Cd alloy bars are primarily used in cathodic protection systems to prevent corrosion of metal structures, such as pipelines, storage tanks and ship hulls. They are also used in the production of specialised alloys and in certain electrical and thermal applications.
Q2. How are Zn‑Al‑Cd Alloy Bars installed for cathodic protection?
Zn‑Al‑Cd bars are typically attached to the metal structure either by welding or bolting. They are electrically connected to the structure to ensure proper conductivity. The bars are installed in accessible locations, thereby facilitating inspection and replacement if required.
Q3. Can Zn‑Al‑Cd alloy bars be used for purposes other than cathodic protection?
Yes, Zn‑Al‑Cd alloy bars are used in the production of specialised alloys, in certain thermal and electrical applications, and in the manufacture of sacrificial anodes for cathodic protection in specific environments.
