Abstract

The invention provides an antibacterial aluminum alloy material and a preparation method thereof. The antibacterial aluminum alloy material consists of the following components in percentage by weight: 2.3-3.4% of copper, 0.5-1.2% of manganese, 0.3-0.5% of cobalt, 0.5-1.1% of magnesium, 0.13-0.25% of samarium, 0.08-0.14% of ytterbium, 0.22-0.34% of gadolinium, 0.15-0.36% of silver, 0.12-0.32% of nickel, 0.5-0.9% of titanium, 0.28-0.50% of zirconium, 0.15-0.27% of molybdenum, 0.08-0.2% of scandium, 1.2-2.6% of silicon, and the balance aluminum and a few inevitable impurities. According to the antibacterial aluminum alloy material provided by the invention, samarium, ytterbium, gadolinium and silver are added into the aluminum alloy material, so that the antibacterial property of the aluminum alloy material is improved, and bacteria breeding is restrained; zirconium and molybdenum are added into the aluminum alloy material, so that strength and plasticity of the aluminum alloy material are improved; cobalt and scandium are added into the aluminum alloy material, so that casting cracks are effectively overcome, quality of aluminum alloy is improved, and the cost rate of the aluminum alloy product is increased. According to the experimental results, the antibacterial ratio of the aluminum alloy product is 99.999% or higher, hardness is 88 HAR or higher, strength is 552 MPa or higher, the elongation is 8.1% or higher, and a flow inspection qualification rate is 99% or higher.
