Title:
HIGH-CORROSION-RESISTANCE COLLECTING TUBE MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/246018
Kind Code:
A1
Abstract:
A high-corrosion-resistance collecting tube material, and a preparation method therefor and a use thereof. The high-corrosion-resistance collecting tube material is formed by compounding an outer-layer alloy and a core-layer alloy. The outer-layer alloy comprises the following components in percentage by mass: silicon: 9.0-11.0%, iron: 0.05-0.25%, copper: ≤0.1%, manganese: ≤0.05%, magnesium: ≤0.03%, zinc: 1.2-1.3%, and titanium: ≤0.1%; and the total proportion of other impurities is not greater than 0.15%, with the balance being aluminum. The core-layer alloy comprises the following components in percentage by mass: silicon: 0.05-0.12%, iron: 0.05-0.18%, copper: 0.25-0.4%, manganese: 1.0-1.5%, magnesium: ≤0.03%, zinc: ≤0.1%, and titanium: 0.08-0.15%; and the total proportion of other impurities is not greater than 0.15%, with the balance being aluminum. The corrosion resistance of the collecting tube material is greatly improved by means of the content of the specific metal components in the outer-layer alloy and the core-layer alloy. After brazing, brazing strength is high, and corrosion resistance is excellent.
