1. Product Introduction: Our company's zinc-aluminum-cadmium (ZAC) sacrificial anode products (abbreviated as zinc anodes) are recognized by the China Classification Society (CCS), and the quality standards comply with GB/T4950-2002. The chemical composition of the zinc anodes meets the US MIL-A-18001H and ASTM-B418 (Type 1) standards. This product features: 1. The zinc alloy sacrificial anode has a low solubility, high current efficiency, and good self-regulation performance for the current generated by the anode. 2. Long-lasting protection, up to 20-30 years, and generally does not experience "overprotection." 2.
