26-gauge wire is a type of electrical wire that is commonly used in various applications, including electronics and crafting. The "gauge" refers to the thickness of the wire, with a lower number indicating a thicker wire. In this case, 26-gauge wire is relatively thin, making it suitable for tasks that require flexibility and precision. This wire is often made from materials like copper or aluminum, which are good conductors of electricity. Due to its thinness, 26-gauge wire is ideal for projects such as connecting small components in circuit boards or creating intricate designs in jewelry making.
