Bimetallic copper-aluminum bimetallic connector for copper strip and aluminum strip
1. Bimetal plate cup alloy:
2. Double metal aluminum plate: ALSN20CU
Mainly used in the manufacture of bearing bridges, ships, vehicles, boilers, pressure vessels, oil pipelines, large steel structures, etc.
1. Experimental method
1.1. Chemical Analysis
First remove about 0.1mm of the sample from the surface layer, and then scrape off the wear-resistant layer, but the scraping depth should not exceed 60% of the thickness of the aluminum alloy. Chemical analysis of scraped alloys where steel, iron and
Manganese element is carried out according to GB6987-86. The "Chemical Analysis Methods of Aluminum and Aluminum Alloys" stipulates that other elements shall be stipulated by agreement between the supplier and the buyer.
1.2. Hardness test method
First remove the sample about 0.1mm from the surface layer, and then measure the hardness of the wear-resistant layer. Three-point measurement per piece (the distance between any two points is greater than 20mm), arithmetic
The average value of the three-point hardness is the hardness value of the test piece, and the test conditions are shown in Table 6.

1.3. Bending test method
Cut the sheet into 15 mm wide test pieces in the direction of rolling. The specimen is first bent to 180° (bending radius equal to the total thickness), and then bent back. During the test, the aluminum alloy and the steel back were bent as an inner layer respectively,
The specimen is allowed to break, but the steel back and aluminum alloy must not be delaminated.
