Abstract

The invention relates to a microalloy copper foil and a machining method thereof. The copper foil is Cu-Fe-Sn-P, and comprises, by weight, 0.010%-0.015% of Fe, 0.0080%-0.015% of Sn, 0.0035%-0.0085% of P and the balance Cu. According to the machining method of the microalloy copper foil, a horizontal continuous casting process is mainly adopted, then four times of cold rolling are conducted, and an annealing procedure is carried out between every two times of cold rolling. The microalloy copper foil is thin, the tensile strength and the softening resistance of the microalloy copper foil are improved, the electric conductivity and the hardness are high, the Fe alloying machining method is simple, and the microalloy cost is low. A radiator water tank made from the microalloy copper foil has the characteristics of small size, low weight, large radiating area, high radiating efficiency and the like, and the microalloy copper foil has practical application and popularization value.

Description

technical field [0001] The invention belongs to the field of metal materials and relates to a microalloy copper foil and a processing method thereof. Background technique [0002] Micro-alloy copper foil is a high-efficiency radiator material for manufacturing automobile water tanks. At present, there are TSn0.08-0.01 (T14405) and TSn0.12 (C14415) micro-alloy copper foil alloys for tube-type automobile water tank radiators on the market. , TSn0.1-0.3 (C14420) and TTe0.02-0.02 (C14530), the mainstream product is TSn0.08-0.01, the product is concentrated in 0.045-0.06mm, and the volume of the tube and belt radiator made of TSn0.08-0.0 Small size, light weight, large heat dissipation area, and high heat dissipation efficiency, but there are still problems such as insufficient light weight, insufficient elasticity after thinning, and insufficient softening resistance. [0003] The weight percentage of strip alloy elements Sn (0.10-0.16%), P (0.005%), Zn (0.02- 0.07%), Ni (0.2%...
