What is the Difference Between Ruthenium vs Iridium?
The main difference between ruthenium and iridium is that iridium is more expensive, giving you better corrosion resistance and durability, while ruthenium is cheaper but still offers good quality. If your major concern is durability, you can go for iridium, while ruthenium is good for those on a budget.
Ruthenium and iridium are two metals that can be used in plugs, with the former being a platinum-group metal while the latter is a corrosion-resistant metal. Ruthenium plugs feature ruthenium electrodes, and they are less expensive but they also wear out faster. Also, plugs with iridium electrodes are more durable but also more expensive.
Most car manufacturers also recommend using iridium plugs because they offer the best performance and are highly durable. But, if you’re on a tight budget or your car is not compatible with iridium plugs, you should use a ruthenium plug. Iridium is more corrosion-resistant than ruthenium, as the latter is a softer metal.
– How Ruthenium Spark Plugs Work
Ruthenium spark plugs have a similar construction to other spark plugs, consisting of a metal shell, an insulator, and an electrode. However, in the case of ruthenium spark plugs, the electrode tip is typically made of a durable alloy that includes a small percentage of ruthenium.
– How Iridium Spark Plugs Work
Iridium spark plugs have a similar construction to other spark plugs, consisting of a metal shell, an insulator, and an electrode. However, in the case of iridium spark plugs, the electrode tip is made of a fine wire of iridium metal.
When an electrical current is applied to the spark plug, it generates a high-voltage spark at the electrode gap. This spark ignites the air-fuel mixture in the combustion chamber, initiating the combustion process. The use of iridium in the electrode tip allows for a sharper and more consistent spark, which results in efficient combustion and improved engine performance.
– Features and Downsides of Ruthenium
Ruthenium is a rare metal that can be found in platinum ores. The metal is a hard, silver-white metal with a melting point of up to 2,500 degrees Fahrenheit. Ruthenium comes with different interesting properties, as it is highly resistant to corrosion, with a high boiling point and melting point.
The material is highly brittle and will shatter if you drop it on a hard surface.
