Conclusion
A ferro rod is a versatile and reliable tool for starting fires, especially in survival situations. It is made from a pyrophoric alloy known as ferrocerium, which includes elements like cerium, lanthanum, neodymium, and iron. When scraped with a hard material, such as a steel striker, ferrocerium produces sparks that can reach temperatures of up to 3,000 to 5,500 degrees Fahrenheit (1,649 to 3,038 degrees Celsius), significantly hotter than other fire-starting methods. The sparks are generated due to the low ignition temperature of cerium, around 150-180 degrees Celsius, which reacts with oxygen in the air to produce these hot fragments.
