Title:
HIGH-STRENGTH CORROSION-RESISTANT ALUMINUM-CARBON-COPPER ALLOY GROUNDING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/000946
Kind Code:
A1
Abstract:
A high-strength corrosion-resistant aluminum-carbon-copper alloy grounding material, including the following components in percentage by mass: 46％-62％ of aluminum, 2％-8％ of copper, 1％-30％ of carbon, impurities: iron <1.5％, silicon <1.5％, and others <1.0％. The corrosion resistance and grounding conductivity of the material are equivalent to those of pure copper. The addition of a carbon particle component improves the hardness and strength of the grounding material, the grounding material can be directly implanted in deep soil in bar form and used directly as a vertical ground, and the alloy has good soil corrosion resistance.
