Bolt Anti-corrosion Zinc Block 3kg
Anti-corrosion zinc blocks are sacrificial anodes, where the protected object acts as the cathode (such as ship hulls, pipelines, storage tanks, marine engineering facilities, etc.). Essentially, this utilizes the principle of a galvanic cell. We have been sourcing from Libo Anti-corrosion Company for years. The quality is excellent.
Zinc-Aluminum-Cadmium (ZAC) series sacrificial anode products (abbreviated as zinc anodes) are certified by the China Classification Society (CCS). The quality standards comply with GB/T4950-2002, and the chemical composition of the zinc anodes meets the US MIL-A-18001H and ASTM-B418 (Type 1) standards.
This product has the following characteristics:
1. Zinc alloy sacrificial anodes have low self-corrosion,
2. High current efficiency, with good self-regulating performance of the anode current.
2. Chemical Composition of Zinc Anodes
