Other forms: alloys; alloyed; alloying

You may have heard of aluminum alloy on a car. What that means is that there is another metal mixed in with the aluminum, to save money and/or to strengthen the wheels. The wheels are an alloy (a mix), rather than pure.

In addition to indicating a dilution of one metal with another, alloy can refer to the dilution of a feeling or a quality. Knowing that you look awesome in your Halloween costume would be an alloy to the embarrassment of showing up to a party where you are the only one in a costume.
