Nickel-free white copper alloy strip foil and preparation method thereof

Abstract

The invention discloses a nickel-free white copper alloy strip foil and a preparation method thereof. The thickness of the nickel-free white copper alloy strip foil is 0.04-0.1 mm, the nickel-free white copper alloy strip foil is composed of, by weight, 5-15% of Zn, 10-14% of Mn, 0.5-1.5% of Al, 0.5-1.5% of Sn, 0.05-0.5% of Ti, 0.01-0.3% of Si, 0.01-0.3% of B, 0.01-0.3% of Ce and the balance Cu and inevitable impurities, wherein the impurity content is lower than 0.2%. According to the preparation method, the nickel-free white copper alloy strip foil is obtained through smelting, horizontal continuous casting, surface milling, rough rolling and cogging, multi-pass intermediate rolling and multi-pass finish rolling, the production process is simple, the process is short, the rate of finished products is high, the white chromaticity is good, environmental friendliness is achieved, and the requirements of building interior decoration, furniture and vehicle decoration and the like for the white copper alloy strip foil can be met.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, and in particular relates to a nickel-free white copper alloy strip and foil material and a preparation method thereof. Background technique [0002] Traditional cupronickel alloy has beautiful and elegant silver-white luster and relatively cheap price. It is often used to make imitation silver and imitation platinum decoration materials. It is the most important kind of low-cost decoration materials. It is often used to make coins, Zippers, buttons, glasses frames, mobile phone cases and other daily necessities, as well as decoration materials for jewelry, gift box packaging, interior walls of buildings and indoor furniture, especially the facade and interior decoration of commercial institutions. The most common white copper alloy is copper-nickel-zinc alloy. However, with the development of modern medicine, it is found that nickel is a typical sensitizing element, which can n...
