Marine Anti-Corrosion Zinc Anodes

Jiaozuo Libo Light Alloy Co., Ltd. has been producing zinc blocks, zinc sacrificial anodes, and various types of sacrificial anodes for many years, with extensive expertise in anti-corrosion. You can trust both the technical construction and the materials provided. We sell marine zinc blocks and other sacrificial anodes nationwide, with daily production ensuring no delays in supply cycles. Feel free to call for inquiries and orders. Marine zinc anodes are available in single iron foot, double iron foot welded, and bolted connection types.

We produce anti-corrosion zinc-aluminum-cadmium alloys for ship exteriors, fixed zinc-aluminum-cadmium alloys, ballast tank zinc-aluminum-cadmium alloys, oilfield anti-corrosion zinc-aluminum-cadmium alloys, aluminum-zinc-indium series alloys, zinc-aluminum-cadmium alloy sacrificial anodes, aluminum ingots, zinc blocks, sacrificial anodes, anti-corrosion zinc blocks, anti-corrosion aluminum blocks, aluminum alloy anodes, zinc alloys, die-cast zinc alloys, zinc anodes, aluminum anodes, zinc rods, die-cast sacrificial anodes, sacrificial anodes for yachts, zinc alloy rods, and more.
The use of zinc as an anti-corrosion metal has a long history. It is well-known for protecting ship hulls, boilers, and the outer walls of internal combustion engine cylinder liners. However, further exploration into materials and installation has only occurred in the last 20 years. During this period, technologically advanced countries like the United States began improving materials and dimensions, while China has continuously achieved results in research on zinc for galvanic anodes. The performance of anti-corrosion zinc with trace additions of cadmium and aluminum has become increasingly effective, all based on high-purity zinc. The principle is sound: zinc corrodes before iron, and ships in the ocean often have zinc blocks attached. While this is feasible during use, especially for personal vehicles, it is more complicated for manufacturers.
During the production of fuel tanks, rust issues can also arise, particularly during storage in warehouses. In internal environments, even minimal moisture or vapor can quickly lead to corrosion. A more appropriate approach is to use vapor-phase anti-rust oil, which requires minimal usage and does not affect the tank's later use, as it is mutually soluble with gasoline. Yes, zinc is more reactive than iron! During anodic reactions, zinc's reducing ability is stronger than iron's, causing zinc to react with oxygen first. This rust prevention method is called sacrificial anode protection.
