In 1905, an engineer was testing heatproof alloys and made a wire that would not burn out, and the electric toaster came into existence

A special metal alloy called nichrome, invented in 1905, made electric toasters possible. This alloy, a mix of nickel and chromium, could withstand high heat without breaking. Engineers still use nichrome today because it is reliable and hard to replace. This invention solved a major problem, making many electrical devices practical for homes and industries.
