Alloys are materials made by combining two or more elements, where at least one of the elements is a metal. This combination results in a substance that typically has enhanced properties compared to the individual components. The primary goal of creating an alloy is to improve characteristics such as strength, ductility, corrosion resistance, temperature resistance, and hardness. Common examples of alloys include: 1. **Steel**: An alloy of iron and carbon, often with other elements like manganese, nickel, or chromium.

The Altekruse Puzzle is a mathematical puzzle related to a specific property of integers. It was introduced by mathematician John Altekruse.
