alloy
意味: A metallic substance made by mixing two or more metals, or a metal with another element, to produce desired properties such as greater strength or corrosion resistance.
Common alloys include steel (iron and carbon), bronze (copper and tin), and brass (copper and zinc). Alloys are engineered to combine the best properties of their component metals — for example, stainless steel resists corrosion far better than pure iron. In British everyday language, 'alloys' often refers to alloy wheels on cars. Figuratively, 'alloy' can mean something that diminishes the purity or value of something else, though this usage is now rare.
